Same general recharge and loss rates at NiMh, but significantly higher voltages. Since Regular Alkaline batteries start at ~1.5, and NiMh start at ~ 1.2 voltage, some poeple have found NiMh are not as long-lifed.

For electronics that NEED the voltage (like camera flashes)it might be worth looking at. Review seem to be positive.

Disadvantages -
requires different charger than NiMh- not compatible.
Not good with non-LED flash lights voltage too high



NiMH is close to 1.3/1.4v hot off the charger and then drops to 1.2v and stays there for the rest of its charge cycle.
Alkaline starts at 1.5v and drops to 1.4, 1.3, 1.2, 1.1, etc over its life so they drop fo 1.2 around 50% of their life.

I get twice as many camera flashes from NiMH as I do alkaline
