This depends on the type of battery. Car batteries are always charged while in use. With other types of batteries, this is not recommended and may result in a battery explosion or damage to the device the battery is powering.

Can you charge a car battery with a motorcycle battery charger?

Unless it's an old vw bug, cars usually run on a 12 volt dc system nowadays. Motorcycles often run on a 6 volt dc system. Different systems require different charging voltages so you won't ever be able to charge a 12 volt car battery from a 6 volt motorcycle battery charger as the output voltage would be way too low. However, if you can set the battery charger's output to give either a 6 or a 12 volt output, then you must always remember to set it to 12 volts if you want to use it to charge a 12 volt car battery.


Can I use a 3.7 v 750mah battery in place of a 3.7v 650mah battery?

It is always best to replace batteries with identical batteries. However if the replacement battery has the same voltage and the same physical construction (so it will connect electrically) it can usually be used as a replacement. The mah rating (capacity) only says how long it takes to charge and how long it will run between needing a charge. However some charging circuits might experience problems if this rating is significantly different from the original.


Does mAh matter when replacing a battery?

mAh is a measure of the amount of charge stored in a cell or battery (set of cells). One (1) Ah is the equivalent of 1000mAh, and so the statement can be made that a cell with 2000mAh of stored charge can supply a device drawing one (1) mA for 2000 hours -- before needing replacement or recharge. It also means 1/1000*C/s*3600s.(1 milli= 1/1000, C=Unit for charge, s=seconds) which finally means that a battery rated 1mAh can hold a charge equal to 3.6 coulombs of charge.


Can you use a dc-ac power inverter to run a battery charger to charge another battery?

No. There are losses involved with each stage of the conversion, from DC to AC, and from AC back to DC. The battery running this would gradually discharge. Any other result would constitute a perpetual motion machine which, in this imperfect world, is impossible.


Can you use a 9.6 volt charger to charge a 7.2 volt battery pack?

Check the internet to see if your charger will automatically step down to 7.2V (not likely if the charger is not the same brand as the battery). If it does not step down then it is possible but *** not recommended ***. Overvolting can cause nasty caustic leaking of toxic chemicals from the battery.

What does it mean for a battery to be multi-charge?

A multi-charge battery can be re-charged while your laptop is on or you can use the AC Adapter port to charge while detached from the notebook. An example is the HP KS526AA 12-Cell Multi Charge Extended Battery. It can add up to eight hours of battery life.


Can you use a 12 volt charger to charge 14.4 volt battery?

It is not recommended to use a 12 volt charger to charge a 14.4 volt battery as the charger may not provide enough voltage to fully charge the battery. Using the correct voltage charger will ensure efficient and safe charging of the battery.

Can you use any car battery charger to charge a battery from an automatic car?

As long as both batteries are the same voltage, you can jump start with the battery. If you want to charge the battery then use a battery charger.


Can you use a 12 volt battery to charge a 48 volt battery?

No


How do you take care unused cellphone battery?

If you aren't going to use the battery for a while or you're storing it, make sure the battery is over 40% charged before you put it away. When Li-ion batteries are stored out of charge for long periods of time, this can lead to an inability to maintain a charge once the battery is in use again.

If there is a hole through your battery, do not use it.no


Is it safe to use a 7.5 charger on a 7.2v battery also is it ok to use a charger with a 100mA higher charge rate than the battery?

Not that i can think of where you'd find a charger labeled for a 7.5 V battery, but - No. A charger rated for a higher voltages won't know when to turn off, and if it's also pushing a higher charge current it's likely to overheat the battery.

Do laptops need to be charged when not in use?

It depends. If you don't want to charge it while in use, then you can charge them when not in use. But if you always charge it when you are using it, then you probably don't have too. But if you only charge it sometimes while in use, I'd charge it while in use.
