The bicycle light seems as bright as it ever was with alkaline batteries, affording good visibility during night time cycling. And stopping play---er, experimentation---with the LEGO robots for recharging has yet to be a problem.

However, I do have to issue this warning: these batteries are slightly fatter than standard AA batteries. I tried using them in a Mini Mag Light. After I got one battery in the light's barrel, I realized---too late---that I'd never get the batteries back out. I ended up destroying the Mini Mag Light in order to retrieve the batteries.

If your application is cramped for space, beware! If they do fit, expect good energy for a good long time.

Great batteriesFeb 24, 2006
By Vlad G
I used to buy excellent Maha rechargable batteries, but finally Energizer attracted my attention. Great price, great capacity. After about 20 recharges batteries are strong and do not show any signs of problems.
I use them in old, power hungry and very demanding Olympus E-10 camera. It is known to draw up to one amper of current and to declare batteries empty as far as their voltage goes slightly below 1.2 volts. Considering number of pictures I can take comparing to Maha 2100 MAh batteries, I can say Energizer is very strong performer and 2500MAh is not just a number.

Some users complained about very bad performance for Energizer.
There could be couple things to consider:
- make sure you have decent charger: many high capacity NiMh batteries can be destroyed easily with cheap (<$20) charger - overheat and overcharge are usual suspects
- some devices expect 1.5 volts, not 1.2 that all NiMh normally deliver; in general freshly charged good set of NiMh has voltage around 1.4 volts - but it goes down very fast to 1.2 v and stays there until batteries are nearly empty. Most modern cameras have "cut off" voltage set to 1.1 v

Update on Feb 7, 2007
I should mention that 4 out of my 12 Energizer batteries suddenly stopped to work. Surprisingly these are four spares I have not used much. I suspect that these batteries may develop a problem if left uncharged for prolonged period of time. For now I have bought Sanyo slow discharge Eneloop batteries (available at Amazon) as a replacement.

Bad product - Much better choices for less moneySep 05, 2006
By Alex Gerardo Renner Meier "Alex Renner."
I bought 12 of these batteries a few weeks ago.

When tested, their real maximum capacity varies between 1100 and 2100mAh, which is very poor, and obviously well under their stated capacity.

I recommend you to get the Sony 2500mAh (which are relabeled Sanyos, probably the best rechargeable battery manufacturer), they all test >2300mAh and cost $5.99, cheaper than these mediocre Energizer units.
