Its pretty hard to beat the Eneloops I thinkthey stay 90% charged at one year . I have some tenergy and powercells and they dont even compare , however I can get 2X for the price of the Eneloops . So its kind of a toss up . if your going to store them buy Eneloops , if your going to use them all the time buy Tenergys

Default I Went With a Rayovac but eneloops Appear Better

I bought Rayovac Rechargeable Platinum on vacation for a camera (they were already charged) and, with their slow discharge, had planned to put them in my portable Grundig G5 AM/FM/SW radio where they'd sit for a year at a time (hopefully).

"Rayovac claims that the Platinum's charge retention rate is... 80% after 6 months, 60% after 12 months [which is twice that of regular batteries and seems to be true for them]. In contrast, Sanyo claims the eneloop can retain 85% charge after 12 months. My own testing has shown that this claim is accurate."

So, apparently the eneloop lasts longer just sitting in emergency gear, recharges at least as often if not more, and costs less. Duh!

Default New Sanyo XX Battery

As a follow-up, the Rayovacs are 2100 mAh vs. the eneloops 1900. But the eneloop, they say, holds 75% of its power for up to three years. However...

Sanyo has a new 2500 mAh battery. It keeps its 75% charge up to a year.

Choices!

Default Apples and Orangutans

I think you are comparing two different things if you meant them to be similar...

Lithium alkalines all hold their charge for almost a decade in the right temperatures, and hold alot of electrons to start! But they are not rechargeable (which, by the way, those Sanyos are repeatedly way more than the Rayovacs).

http://www.batterymart.com/p-energizer-e2-aa-lithium-batteries-2pk.html

So, if what you need emergency backup power for is being put away and is disposeable, Lithium alkalines. Wanna recharge the power supply -- you guys got me sold on the eneloops...

I was told years ago by somebody i can't remember that you could salvage a dead 12v lead acid car battery by catching the acid in it, rinsing it out with distilled water then pouring the acid back in. Can anybody here confirm or deny that?

I have been using the Sanyo rechargeable AA batteries for over a year. They are the best I have found. They last quite a bit longer in my GPS and cameras than other rechargeable batteries.
Side issue; My wife has hearing aids and we have to use Ray O Vac batteries because Eveready batteries dont work. They dont last and wont run the accessories. Her hearing aids have blue tooth connectivity so a phone or TV with blue tooth connect directly to her hearing aids. Eats a little more power and the Eveready are not up to it.

Ive always used Duracell Coppertop, they last the longest of any standard battery ive tried. We use them in everything minus our digital cameras cause we go with the lithiums in the cameras.

Does duracell make rechargeables?

I was in the auto/truck electric business back in the 70s. We could get a battery to come back sometimes with fresh acid. Never tried what you are talking about. If you had no choice, you could try it. The distilled water might help rinse some of the coating off the lead. I would advise you to be VERY CAREFUL pouring out acid. It will burn you bad and ruin just about anything you get it on. Regardless if you use new acid or reuse the old stuff, you will need a good charger to "jump start" the charging process of your battery.

Good luck and be carefull if you try this out.

Jimmy
