Energizer Rechargeable Batteries

Anyone had experience with the Energizer nimh batteries, and of so what is your assessment? They are made in Japan, but I have no idea by whom.


I have an assortment, most older, non-LSD. some are quite good, some are pretty mediocre. I have no idea about newer ones.

Its mostly what I use for AA’s. I don’t really have much to say, good or bad. They work and they’re everywhere. Mine are 2300 mah but I can’t say much about battery life since I just swap them out whenever I notice them get low. They seem to put out the same power as regular batteries even though they’re a lower voltage. In the AAA’s that’s more of an issue though. So far, in all of my flashlights that use those 3 AAA units I notice a weaker beam with the rechargeable batteries vs regular batteries even with the cheap ones. Again, this is with any rechargeable AAA’s I’ve used, not just Energizer. I’m sure its just because they’re 1.2 volts instead of 1.5 but I can’t seem to find any rechargable AAA’s that run at 1.5 volts. My c30’s just have a slightly weaker beam with them, but I’ve got a couple of Utilitech brand flashlights from Lowes and using the rechargeable it is a much more noticeable dip in brightness and they seem to flicker a bit. If anyone has any recommendations for 1.5 volt AAA rechargeable, it would be much appreciated.

Thanks for the replies. I think I will stick with the Duracell ion core if I buy more.

There are no Ni-Mh 1.5V batteries but there are Ni-Zn batteries with 1.6V.

It is not only the voltage that makes a battery better, Ni-Mh batteries can supply more current at 1.2V, and the power is Volts x Ampers.
sk68 flashlights will perform better on Ni-Mh rechargeables then primaries.

I have about 10-12 Energizer AA’s of 2300mah, made in japan, and specified holding charge over one year (so LSD).
They are good, but I can not say they are better or the same as Eneloops.

Yeah overall its probably better to have a more consistent 1.2v than one that drops off more over time. I haven’t noticed a huge difference in primaries vs rechargeables in my SK68’s but I haven’t done any real testing either. Hmm, I wonder if any of my 3aaa flashlights can handle lithiums?

I have been using Energizer LSD 2300mAh (green-themed) cells and they’ve been great. You know they’re LSD when it says “pre-charged” and “holds charge up to a year.”

They perform pretty well, although I haven’t done extensive tests. Probably as good as Eneloops, as they probably are re-wrapped Eneloops.

Although there is certainly nothing wrong with these batteries, I doubt they are rewrapped Eneloops. The biggest problem is the capacity. Simply put, there are no 2300mAH Eneloops. Only 2000mAH and 2450mAH.

That’s a good point, thanks for pointing that out.

When shopping for NiMH batteries, stick to the Made in Japan ones as opposed to Made in China ones. The quality is very different, as demonstrated by capacity and longevity.
