The battery on my cordless dect phone is not holding charge so i want to try swapping it.
The original is 1.2v 600mAH.......the replacement i bought is 1.2v 800mAH........is this the same?

I thought the mAH was just the storage capacity.

The battery capacity is slightly larger i.e takes a wee bit longer to charge and lasts a wee bit longer but it shouldn,t be a problem.

How can it be the same if it's different?

But it should work

All it means is that you can draw 800mAmps/Hour instead of 600. Think of it as a 'pull' effect. If you pull less than 800mAmps/Hour out of the battery, then no problems. Volts are the one to watch - the 'push' in a battery.

yes, as long as the voltage is the same. this battery will just take longer to charge and last longer.

Almost right. 600mAh means that the battery will supply a continuous current of 600mA for an hour before it goes flat. An 800mAh battery will supply 800mA for the same time before it needs a recharge.

It's up to you how fast you actually discharge the battery. To a first approximation, you can discharge the original battery by drawing 600mA for an hour, or by drawing 1200mA for half an hour, or by drawing 300mA for two hours. It's just a measure of the battery's total capacity. More is better.

As long as the voltage is the same - 1.2V in this case - then you should be OK.

Thanks....its what i thought,i'll try it in my phone.
Basically you're saying it should last a bit longer than the old ones.

Cheers guys.

It's correct. And to put your mind at rest I fitted higher capacity batteries in my DECT phone when the old ones blew. A year on all's fine

Great explanation Andy

Thanks Andy, I was keeping it basic.

I have a laptop that uses Li-On batteries, cracked the battery case open when the old ones died and replaced the batteries with higher mAH ratings. Just worked for longer!
