Noticed their review states that they had better runtime on NiMH. Make
sense to some degree. Medium-drain devices tend to be very inefficient
at using alkaline capacity. Alkalines tend to last longer than NiMH
when the drain is really low, like with a low-power LED.
I was told that NiMH cells had a higher self-discharge rate and that
alkaline cells were better if you were not constantly charging them.
Use the (newish) NiMH batteries that come ready charged. I use Uniross
Hybrio, they do not self discharge like the normal ones, hold a charge a
heck of lot longer. They are also a bit cheaper If you do get some do
not bother to recharge any backup batteries when have to do a swap wait a
while that also helps.
I mentioned Sanyo Eneloop, although they resell their low self-
discharge batteries to other companies to re-brand.
Self-discharge is also heavily dependent on temperature, even with
alkalines. I've also had bad results with alkalines stored in hot
conditions. If they don't lose a good chunk of their capacity from
self-discharge, then they'll leak like crazy. The 85% claim is
probably at about 70 deg F. If you keep them warmer (imagine taking
your camera on summer camping trip), I think you'll find that self-
discharge is considerably faster.
