Rechargeable batteries; using chargers with different mAH RATING?

Question

Can I charge 2200 mAh batteries using a charger rated for 800 mAh batteries.

Conversely, can I charge 800mAh batteries using a 2200 mAh charger?

Thanks

There is not a simple answer to your question.

It really depends on the charger design and the type of battery.

I am assuming you are actually talking about cells.

Although we all call cells batteries, a battery actually consists of two or more cells connected together in series to produce a higher voltage.

Generally speaking however you can do either (especially with modern day chargers).

If you use a lower capacity charger to charge a higher capacity battery, it will simply take longer time to fully charge the battery.

If you use a higher capacity charger to charge a lower capacity battery, the circuitry inside the charger should limit the output current to a safe level.

A higher capacity charger will not be able to charge a lower capacity battery any quicker however.

If a battery has more charge current applied than it is designed for, it will overheat, damaging the battery, and possibly explode!

That isn't an exaggeration, I have seen it happen a few times and in fact I've done it myself while playing around.

I at least kept a safe distance away, unlike a co-worker who nearly lost a thumb about 25 years ago.

The above is just for informational purposes only, based on my knowledge and experience of 35 years working in the electronics industry, and not to be considered as anything other than general guidelines.

To give any more specific help, I would need to have a bit more information.

You are welcome to blast me an e-mail with more information and I will do my best to be of assistance.

Hope this helped a bit.

Good Luck!
