alkaline versus NiCd or NiMH battery

[patrickpdk]

I bought a cordless mouse that takes 2 AAA batteries. I found that
these wear out after about 2 weeks and want to get rechargable
batteries but the device says "only use Alkaline batteries" - does this
mean that I cannot use rechargable NiCd or NiMH batteries? Will these
batteries blow up my mouse?! )

No. But the rechargeable cells put out about 1.2 volts each, while
the alkalines produce about 1.5. So the mouse will not work as well
on the 2.4 volt total as well as it will with 3 volts.

Others have stated the lower initial voltage of NiCd & NiMH.

I was thinking of rechargeable alkalines,
but even then you will be swapping out batteries often.
To get maximum life from them,
they must be replaced and put back on the charger
before they have been deeply discharged.
