Unreliable Energizer 2500 mAH AA experience,
This review is from: Energizer Recharge Power Plus AA 2300 mAh Rechargeable Batteries, Pre-Charged, 4 count (Electronics)
I've been using NIMH batteries from SANYO, NEXCELL, POWEREX and AccuPower for over 6 years. Use them for everything from high current drain digital cameras and high-end digital audio recorders to CD players, bathroom scales and flashlights.
I rely on two of the excellent MAHA MH-C401FSB smart 2-rate chargers. These charge and monitor each battery independently, not in pairs. Energizer 2500 mAH units were fine for about three months. Then I noticed that devices would be calling for new batteries with little to no use. This has never happened with other AAs NIMH, including those with less than half the advertised capacity. The MAHA charger also started reporting that some of the Energizer AAs were not taking a charge at all.
Kept finding that typically one out of four were the problem. Many of the 32 AA Energizers I bought have had problems. Repeatedly have had one battery run out of charge while others still test very strong. Felt pen dots put on discharged batteries showed it was the same batteries time and time again. Have reverted in some cases to 1600 mAH SANYO OEM batteries put in service in Feb 2001 and those provide longer and more reliable performance!
In my considerable experience with these 2500 mAH AA Energizers they have been a very big disappointment and, regardless of warranty, cannot be relied upon.

Heads up, people. This review is not for this battery. This is a 2300 mAH battery which does not share the same issues as the 2500.

I have used ~16 Energizer 2500 mAH AA batteries for ~7 years and, almost from the start, they underperformed my ~30 1300 mAH GP brand AA's, which I had acquired about 3 years before the Energizers. The performance difference was particularly noticeable when installed in a low drain device like a remote control, where the Energizers would require recharging in a few weeks, instead of 6+ mos for the GP's. More recently, I've been very pleased with the performance of 48 Tenergy Centura AAA low self discharge batteries purchased over the past year and have recently ordered 24 in AA size, since they average about half the cost of Eneloops. In my experience, a smart charger is essential for obtaining maximum performance and monitoring the relative "health" of my NiMH batteries.
Energizer Customer Service advised me that this (made in China) battery was only designed to last 2-3 years. Had I been aware of that information, I would never have made the original purchase. The fact that my 10 year old GP's continue to hold a charge far longer, suggests that Energizer marketed an inferior product. Hopefully, for the benefit of current users, they've made improvements.
