This battery has almost been beaten up as badly as the La Crosse BC900 charger on these forums though the height of the complaints came about two years ago. My wife, just like countless others, had favourable impressions of lower capacity batteries that most thought would scale with the added "mAH"...no wonder there was such an outcry over their crappy performance. As most people had dumb overnight chargers, the issue seemed to be three fold:
Ironically, one of the things to come out of this was the re-design of the Maha C9000 with its 1.47V termination strategy. It may be the only charger out there than can deal with these batteries in a "smart fashion" without overcharging them.
For those of us, like me, who do not have a C9000 to babysit their Energizer 2500, what are we to do ?
I propose the following:
Top ten list of things to do (or not to do) with Engergizer 2500 batteries:
- Dead batteries that were charged just a week ago performed worst than the lower capacity batteries.
- Low number of shots in current hungry devices like digital cameras due to voltage depression.
- Voltage depression induced by self-discharge below 0.9V and storage at that condition...can you say destructive cycle.

Top ten list of things to do (or not to do) with Engergizer 2500 batteries:
- Use them in toys or simple flashlights until they run out of gas to give them a near full discharge. Stick in a dumb overnight charger that times out. Avoid smart negative delta-V chargers.
- Use a simple discharge circuit (diode + resistor) to charge them before charging them in a dumb charger. Again, avoid smart negative delta-V chargers.
- Do not use them for digital cameras
- Use them to test the time-out capability of your smart charger. Best be done on discharged 2500s so that you do not beat on them anymore
