I need some Ni-MH batteries for my BT handset.

The ones in at the moment have lasted about 6 years but don't hold the charge very long now.
They have 550 mAh on them - what's the difference between those and 700 mAh?

Ta.

what would scooby do

about 150 mAh

I use Duracell AAA rechargeables for my home cinema's "doofer" (my all-in-1 URC ). They're awesome - last a good month or more until they need recharging again (and that is using the URC a lot!, and every single day!)

If you think of a battery as a bottle or a sponge that you can fill up with electricity (or that comes pre-filled or pre-soaked with it, if it's not rechargeable), the mAh number basically tells you the size of the bottle or the total amount of electricity the sponge can soak up.

Ba dum-tish.


Ok, so 700 or 1000's are going to hurt the handset?

Cheers all.

Wouldn't have thought so.

Just means the higher the mAh, the longer preiod of time it'll take for the batts. to drain down. So, they'll work for longer bouts/require less frequent charging events.

No. What matters to the handset is the 'V' of the batteries, which in my analogy would be how quick the electricity pours out of the bottle into the handset. If that's the same (remembering that most battery-powered items will tolerate a small amount of variation, and some a relatively large amount), nothing to worry about.

mAh = milliAmp Hours - so how many hours the milliAmps will be produced for at the specified Voltage of the battery.

Simply a 1000mAh battery will last longer between recharges.

Eneloop are another option as they hold 75% of their charge for up to 3 years

As long as the battery voltage is correct then no damage would ensue

The higher capacity batteries would last longer before they need re-charging.

Thanks chaps.

Ordered some 1000's.
