I have all the Crickets, the Cricket-Key, The Muriana and theI have had mixed experiences. I got two Imedion rechargeables and the
Maha charger. I am 98% sure these were 9.6V nomimal batteries, with 8
cells, vs the 7 cell 8.4V nominal. My general impression is that
8-cell batteries are preferred.
With so many cells in parallel, they seem prone to damage from a
reversed cell. One of my two batteries seemed to have a slightly weak
cell to start with, and now, maybe 6 yaers later, the other seems
troubled. Compared to AA cells, with which I've had great experiences,
I wasn't really happy with them. But, the basic issue is that the 9V
battery is a very difficult form factor.
I recently contemplated getting a new one to try:
which is said to be 8 cells, but 9.9V at "full charge" doesn't really
compute, as charged-and-resting is usually 1.35 Vpc for NiMH.
Apparently powerex (same as maha/imedion) has both 8.4 and 9.6, with
I would also wonder about making a regulator to 9V from 12, and some
snap connectors, and operating off a power supply or larger battery even
