Understanding the specifications. EN EN Reserve Capacity Minutes EN Obviously, the more electrical accessories you turn off, the further you can drive the car. Recommended Charge Rate Amps This is the recommended current for charging batteries with a constant-current charger. Dimensions — Length mm This is the dimension over the longest part of the battery, including the hold-down if fitted. Dimensions — Width mm This is the dimension over the widest part of the battery, including the hold-down if fitted.
Dimensions — Height mm This is the overall height of the battery to the tops of the terminals if these are proud of the lid. Weight with Acid kg This is the average weight of the battery as supplied.
End-Venting There are now several batteries in the range that have end-venting, rather than the normal venting through the individual vent-plugs. The status of battery has to be checked every weak, while you check the cold inflation pressure of the tire. To have a optimal inflated tire, means an optimal tire foot print i. If not using a vehicle use a battery tender that start charging at Not hapy with comercial battery tenders, I made my own using a NE timer as precission comparator an more component.
I can adjust ON at Increasing the battery voltage above The weak cealls continue to charge and the strong start boiling. I do this proces at mA untill battery saturated, and after turns OFf to let battery to relax. I never buy a maintenance free battery, because I must check the electrolyte, level, top with H2O, and if necessary check the density. Marie Sir Good day!
Jeremy Sounds like you should talk to the manufacturer. The 7AH will last longer than the older 4. If so, does it make any difference what side it lies on battery posts toward the top vs toward the bottom. Jeremy Dave, you can use an AGM in any position, except directly upside down. Anders D Best written, most through article I have read regarding batteries, thank you!
I purchased a CTEK multi us 4. I attempted to charge 3 days after installation, but became concerned as the charger was hot to the touch after 2 hours and still in the bulk charging state. Should I be concerned by the heat?
There was no indication of anything awry other than the charger itself being hot. Interestingly, the old battery never remained in the bulk charging state this long and I never experienced the charger ever being warm. Jeremy I would not be concerned if it is hot after 2 hours, but if it has not entered into maintenance mode after 12 hours, I would check the battery to ensure it is good.
Athar During periodic check when I observe that water level is low, I add distilled water to cells of lead acid battery. After a short time the fluid starts oozing out from the caps. It continues for about 12 hours. What is the cause of this problem and how it can be rectified? Harold Thanks for a very informative article. I own an older Honda Goldwing with lots of electrical gizmos.
I have replaced the battery twice in last year. My dealer replaced the last under warranty about three months ago. The new battery worked fine when I was driving the bike frequently.
But after letting the bike set for about two weeks I now have another dead battery. I hooked up my trickle charger, it only has a light that tells me it is charging, I left in on for about a week it did not recharge.
I then hooked up my battery charger, it tells me it the battery is fully charged at 6 volts. Does this mean I have three bad cells?
This is the second time this has happened, the first new battery lasted about six months this one about three. Do you think I got bad batteries. One I think maybe, but two in a row.
We brought it home and put it in the basement workshop, but I discovered tonight that it was down to 10 volts. The article says AGM batteries are the safest type, so would it be safe to charge it in the cold room?
John Brilliant article. Has really explained the internal working of various makes of batteries, better than anything I have come across here in the U. Pulkit Hi. I just want extra backup. Please reply me anyone ASAP. Robin Brokaw Here is an article that explains the answer to your question.
Should you have any further questions please feel free to email our tech guys at tech batterystuff. Sandie I am battery deficient. I am charging a battery on trickle charge, I know that much, but how do I know what the red and black bits on the charger mean?
And how long til it charges? My hubby used to do all this but alas he is no longer here. Thanks for input. If you want to send me a photograph of the charger in question, my email is tech batterystuff. Donna I need a battery for a lighting setup for artfair booth outdoors. My battery shows In the motorcycle it shows This happens when a weld point begins to come loose in the battery and it is unable to pass any significant current along the now thin connecting point.
John I have a 12v amp hour wet cell battery at work. It was taken out in the fall and put on a smart charger. Now I was going to reinstall it back into our equipment. I noticed that the end with the negative post is swollen. With a load test it passes at 9. Could the one cell have pressured up and not vented? Jeremy Fear It could have had some gassing at some point without actually damaging the cell, as may be indicated by the continued performance.
Sean Question, i have access to some lead acid batteries with much more life left in them….. I want to put some in extremely long storage 5to10 yrs Can i remove the electrolyte, flush then store? I read somewhere after flush to refill with ph neutral water and storing worked well. Another that after flushing used inert gas argon and sealed battery vents. Not concerned with losing a little capacity as these are very robust batterys. I would charge these fully then remove electrlolyte and store it properly until redeployment.
Tim Great Article. If I have a 80 Amp Hour battery and use a winch that is drawing Amps under load with a 90 Amp alternator on the vehicle, how many minutes can I winch before I fully drain the battery or cause the vehicle to turn off? What formula are you using? Donny Do you recommend a 2 battery solution for a boat? Or would a dual purpose battery be sufficient?
The engine is a 90 hp outboard. BatteryStuff Tech We recommend using a dual battery setup versus the dual purpose batteries. You get better performance for your needs this way starting the engine and running your electrical system. Jerry Anderson I have a Yamaha golf cart I purchased 4 yrs ago. By spring the batteries were so discharged thatmy cart charger would not work. I used a car battery charger to charge the 4 12V batteries separately.
I limped through last summer having to charge to cart every 18 holes. I haave recently read about de sulfating the batteris. I was thinking about trying this before I spring for new batteries. Can you recommend a product to do this and if I can use the cart charger when doing this or would I have to charge the batteries individually.
Thanks for the great article. Reg Rayner Sir, Thanks for the article. These are constantly charged by both solar panel and wind generator through a regulator and also charged when the motor is running by alternator.
My question;- Can I replace these wet cells with AGM batteries without changing any charging facilities? I have a manual idiot switch, for selecting each battery bank or both.
My motor is a Ford Lees 85 HP deisel. Thanks in advance. I recommend using deep cycle and starting batteries for their respective purpose. Could we have damaged the battery by using it in a different machine? The bikes take different size batteries with different amps but both 12 volts. BatteryStuff Tech There should be no issue using a smaller 12 volt starting battery for the motorcycle.
If the battery is truly fully charged, can you provide a resting voltage reading bike off? Mizanur Rahaman Sir, I want to know a matter. When a 12V, 7. Please ans. BatteryStuff Tech Whether or not current is going into the battery after being fully charges is entirely dependant on the model charger you use and therefore I cannot answer your question.
However, if you want to know what resting voltage off charger on the battery itself is considered full charge, please refer to this article for the answer. Silas Sir I will be very thankful if you guide me to build a charger of a 4 volt Li ion battery which I have dismantled from my old laptop battery ……Thank You.
BatteryStuff Tech We are unable to provide you the information you need. We are a reseller. We do not build or manufacture any chargers. One guy called a battery looking like a 6-pack of soda cans a gel battery, where as the guy he called in for more info called it AGM , which it probably actually is. Thanks for a great website!!!!!!!! Mike Smith Very Informative! I assume 1 to be the highest rating. It has a single alternator and a separate voltage regulator.
With the engine running, one battery reads I assume this means the alternator is trying to charge this battery more? At that time, one battery was reading I discovered I had bought the wrong regulator, so I bought a second one. It read 16v and 17v. Would my assumption be correct, and should I replace the battery with the higher voltage reading or both? What started this was when I bought the rv, before driving home I turned on the headlights and one went out immediately.
I left it for him to fix. He replaced both headlights. The first time I used them the new ones went out together. BatteryStuff Tech They do make 16 volt batteries and alternators. They are commonly found in race cars. You could be overcharging your batteries. Garry Mcdonald RE; Can anyone please help? Scooter battery problem, will not take a charge. It appears that there may not be anything wrong with my batteries.
I was told that the batteries must be charged every month or two or sulfation would set in. But the batteries not excepting a charge after 4 months was concerning. With no answers I decided to drain the batteries of two scooters by running the motors with the throttle on full and turning the lights on.
However after 5 hours of constant running the scooters meters were still showing full and the volts where at After 5 hour only dropped 2 volts while protection shutoff is 42 volt.
The next day I charged the batteries and yes they took a good charge, 7 hours and still taking a charge when I left for the day I have them on a 12 hour timer. These Chaowei deep cycle gel batteries must be very good with little self discharge to not except a charge for 4 months.
Batteries that are fully charged for a 48v system should give you Louw Penni Ng Hi, Very informative article, thank you. When ignition is off, the fridge stop drawing current.
However, the truck batteries constantly run flat during driving, all well while I drive diesel truck , but next morning the truck batteries are almost flat. Currently the 12 volt fridge element draws amps from the second 12 volt truck battery, this implies that the fridge uses the power from the battery, not directly from the alternator. Is it possible that the power outflow from the battery is more than the charge inflow into the battery?. How many Amps can a battery continuously take while charging?.
I now think I must tap the 24 volt directly from the alternator, then put it through a rectifier to get 12 volt, and then onwards to the fridge.
This will leave the truck batteries free to charge at will without being drained by the fridge. If the truck batteries can only charge at say 6 amps, while the fridge draws 10 amps, the current set up will always discharge and leave me with flat batteries.
Am I correct in my reasoning?. Please advise asap, Many thanks, Louw. BatteryStuff Tech There is no limit to what a battery can or cannot accept.
For a 50 AH battery, that would be a max of It sounds to me like you have a 24 volt battery system, but a 12 volt alternator. It seems like the fridge only takes 12 volts to run. What part of your system actually draws from 24 volts? Ed i have 3 sb s 12 volt 10 amp batteries for my bike which were stolen how do i wire the new ones?
Ed i have 4 batteries ps fs 12 volt 7. Mike I use 4 — 12 volt dcm interstate batteries hooked up to 48 volt configuration to power my pedicab. I have 2 sets-8 batteries total. I use 2 noco gen 4 chargers. Mostly in the 10 amp mode…. Weather conditions from 35 — F. How can I determine how much life is left? Besides the obvious based on how long they run before being drained. BatteryStuff Tech There is no magical formula to predict the length of life remaining in a battery.
Andy I purchased a used boat in , it has 2 identical West Marine starter batteries CCA with a Perko 3 way switch, 1, 2 both or off.
The engine is a HP Suzuki, with a 44 amp alternator. Should I go with 2 starter type batteries or 1 starter and 1 house? While boat is running is the alt charging both battery at the same time or does it follow the path of the Perko switch? Thanks, great site. BatteryStuff Tech Since the batteries will be connected together via switch, I recommend using two of the same battery types and sizes.
Therefore, if the batteries are used to start the engine I recommend two starting batteries. I recommend a deep cycle battery if you need 12v power while the engine is off. BatteryStuff Tech No.
If you are charging a battery and then you use it at the same time, the charger will attempt to supply the load. Depending what the load amount is, and if the charger can supply it, the battery may be charged at a lower rate or not at all and start discharging instead. Here in India we use V Ac for our appliances. Murugan i bought a 12Volt battery 22months back with inverter for my desktop computer only.
The dealer told me that i can use it for 10 and half hours for to power my computer only. I always carefully kept the water level full by regularly checking the level indicators. On an average i use the battery up to 7 to 9 hrs these days because of big power cuts here and see it charged fully immediately when power comes. My questions is will it affect my battery life by leaving it to be charged in alternate hours?.
The truth is, the battery is going to build sulfation when its in a discharged state. Re-charging it will reverse this. Less is fine, but no more for safe re-charging. Any Help. BatteryStuff Tech What is the amount of draw load on the battery when its in use? And with the same load it gave me a Backup time of almost 2 to three hours. Sounds like the battery has sulfate crystal buildup on the plates.
Sulfation causes batteries to age quickly. Refer to our other technical articles about how to remove sulfation. The standard rating is an Amp rating taken for 20 Hours. David Cuneo Thank you for your article, I have a question.
I repaired the plastic casing,it could now hold liquid safely. Could i add electrolite from an old battery or would that have too many sulfites , it would be better to get a motorcycles worth at autozone? I am going to turn in my old battery anyway as it is a core charge… What do you think? BatteryStuff Tech The moment oxygen hits activated plates in a cell, sulfation will form rapidly.
My opinion is that it's not worth the effort or the risk. I recommend buying a new battery. Even if you were able to restore this one a bit, I doubt it will last very long and it would not be safe as the internal resistance when charging will be greater than a healthy battery, which you will risk the battery overheating as a result.
Wilfred Kube I have a Toyota Coaster bus which is fitted out as a motor-home. The vehicle was manufactured with a 24 volt electrical system, which uses two batteries in series, of 12 volts each. I have outlined a description of the auxiliary electrical system below, but my basic question is, how can I know how depleted my auxiliary batteries are at the end of a day in which the refrigerator has been working for a long time? The refrigerator is the major user of battery power, because it is a compressor fridge which uses the equivalent of 12 volts 8amps i.
The auxiliary batteries are charged by two solar panels of 80 watts each, and receive additional charging from the vehicle alternator when the engine is running. There is a battery isolator which automatically disconnects the auxiliary batteries from the vehicle electrical system when the engine is not running. The voltage regulator for the solar panel charging system provides a constant display for the auxiliary system, including the auxiliary battery voltage.
I have been in the habit of checking the voltage last thing at night, and first thing in the morning, to find how much power the fridge has taken from the batteries. If the night time voltage is below The problem is that if we have not done much driving on a particular day, and the solar panels have not done much charging because of cloudy weather, the night-time voltage may only be If the battery is at And so my question remains, what is the lowest acceptable voltage for my auxiliary battery system, so that the batteries are not damaged by being discharged too much.
Thank you for reading through a long and detailed letter, but I wanted to provide sufficient background information. BatteryStuff Tech Resting voltage of When you reach this point, stop using the batteries until you can recharge them again.
Wilfred Kube Thank you very much for your helpful site,and for your prompt reply to my query. Unfortunately, on a trip last week I lost power faster then ever and ended up having to only use the refrigerator while driving, forgetting about the water pump or the coffee maker; I tried to recharge the batteries since then but the charger wont go over 10 volts and goes down to 8 and 7 after 10 hours My question: since these trojan batteries are very expensive where I live Peru should I invest in a charger, what kind, and should I charge the batteries everyday from my house?
The car is in the street and I cant go check every 2 hours what the voltage is, so is there a charging process that is safe, guaranteed on the long term for these batteries? Once again this is the full description of my configuration: bus sprinter with alternator of Amp starter battery of Amp 2 trojan deep cycle amp each output 12V one tripp lite inverter V 2, Watts Thank you so much for your answer which should interest many people like me who just want to understand how to run a simple 3 or 4 devices in their camper.
BatteryStuff Tech It sounds to me like your current charger is probably fine but the batteries may be defective or had their life significantly reduced when they were overly discharged those 2 weeks ago. Peter Thank you for your great work! I have learned a lot. I have two questions relative to this:.
Are dangerous gases given off while the battery is plugged in and receiving a trickle charge? My battery is plugged in in the basement workshop in a fairly large house. There is probably a good amount of sulfate crystals on the plates in the cells, which would cause the charger to work harder to maintain the float mode.
Sulfation robs the battery of power, but can be reserved with de-sulfation units and chargers. Gassing should not be an issue if the battery is healthy.
Only significant over-charging should cause an AGM to vent excessively. Matt Great article. Is that what you would recommend? Again, this battery will be used year round. Freezing cold when it sits for days at a time without being used, then it will be used on the weekends when I go fishing.
Then during the summer it will be used in the heat. I do have a generator that i plan to use to recharge the battery when necessary, but am wondering if it would make sense to leave a solar charger hooked up to the battery constantly.
Then even when in use, the battery would be charging, right? BatteryStuff Tech For extreme temperatures, the Gel batteries are the best. They also have the slowest discharge rate.
Having a solar panel is a great idea, and perfectly safe even if a generator is on or you are using the batteries, if you are also using a solar controller which regulate safe charge voltage levels, and prevents back feed into the panel. But yes, if a solar panel is receiving sunlight, the battery will also be charging as well.
Never saw a gel battery with that type of operating temperatures. I have one in in my truck. Never a minutes worth of problem. BatteryStuff Tech Pure lead vs recycled lead does make a difference in performance. NorthStar batteries sounds like good batteries. Adam Johnson Thank you for your opinion…. I would like to use an electric golf cart for in-town transportation in a small town in the San Juan Mountains of Colorado, year around. I am a teacher and typically only drive it back and forth once or twice a day, about one mile each way.
I have a 36 volt charger that came with the cart. The cart is perhaps 20 years old. The batteries it came with were all exhausted, I took them to a recycler. I was thinking of spending the BatteryStuff Tech For the greatest range of operating temperature, the gel batteries would work the best. For a solar panel, you would either need a single 36 volt panel, or 3 12 volt panels in series. No core needed. Contents show. What Are Ampere Hours Ah?
What Are Cold Cranking Amps? Still have questions? Leave a reply. If you have a car question, submit it to our community for a faster answer. Cancel reply. Your Comment. Leave this field empty. Related Posts. The amp, on the other hand, is the measurement of the electron flow and current within a conductor. One Ampere refers to one coulomb of electrical charge that transmits all across the conducting item within a second.
The Ampere rating is the battery operation threshold that gives an estimation of the battery charge. From this rating, you can calculate how long the unit will last without recharging.
A battery unit will have this rating written out on a label. The measurement unit is either Ampere Hour Ah or milliampere hour mAh. If you live in a cold region, the CCA rating is useful in determining the better battery for low-temp conditions. The rule of thumb is the higher the rating, the higher the capacity and power. You can choose a more powerful, better battery by knowing the starting power, but the CCA to Ah conversion is necessary for knowing its capacity.
When you purchase a new car battery based on the CCA values, you will need to convert it to Ah. The problem is there is no direct correlation between these values. Worry not!
