Originally posted by ZombieArmy NiMH are great. Alkaline are the devil, exploding and ruining electronics.
There are NiMH's and NiMH's:
Most NiMH's lose charge quite quickly, that was their downside when they came after NiCd.
NiCd's had that bad problem called
memory-effect
but some NiMH's had that problem as well.
I remember when for my orig. "made in Japan" Makita cordless drills and screwdrivers which used NiCd's NiMH's were offered.
The NiMH battery had more power (3A against 2,1A of the NiCd's). It was nice at the beginning, the power and capacity was superior
but when not used the NiMH was empty after 2 month or so and needed to be checked regularely because if it discharged too much is was finished.
After 3 years the NiMH was useless but I still can use the NiCD's which now are over 11 years old and only now start to lose capactiy.
The other ones which I purchased 2013 are still fine
The two Li-Ion batteries of another 14V Makita purchased 2014 is getting weak as well.
Amazingly early 2006 Li-Ions from my K10D are still alright!
I also have a few made in Japan D-LI90's since years which still are very great.
