Energizer 2650mAh Rechargeable AA Batteries - Pack of 4 - Direct Ship offer
2650mAh
Size: AA
Can be recharged 100s of times and save money
Environmentally friendly - no harmful cadmium, mercury or lead included
No memory lag unlike cadmium based rechargeables
Is that a bargain? Not sure. Do I need a 2650 maH charger to charge this?
I don't believe you need a special charger. It just takes longer to charge.
these go flat in 1wk after charging
they also get real hot and self damage during charging, after a year they have about 400mah capacity
speaking from experience.
yep, same with a pair i had, don't get these, spend money on a good set of eneloops
Yes I agree about the 400mah after some time.
They won't last as long after a while.
You can get 4x 2900mAh rechargables for $15

The Energizer ones claim up to 250 recharges…the Vapex ones are 1000
I bought 8 Vapex AA 2900mAh batteries less than 4 years ago. 5 of those have already been sent to the recycling bin as their real capacity fell far short of that stated on the label.
'up to 1000 charges' is usually marketing speak, not a technical specification.
Wouldn't buy these Enrgizer or generic unknown branded batteries. I have in the past and they don't last very long even the 2700mah+ rated ones. Was forever recharging them. I have since ended up switching to Sanyo Eneloop low self discharge batteries and would never buy anything else. They last several times longer.
no AAA -_- ?
FYI, I have used Energizer recharables and they are useless. They go flat so quickly. I have some no-name brand recharables that last so much longer. And of course, nothing beats the Eneloops.
I had a half dozen of these energizer rechargables lying around . They are absolute crap . They lose charge rediculously fast . Any of the "ready to use" , "precharged" or LSD "Low Self Discharge" batteries are far more useful .
I can only agree - I've owned a lot of Energiser rechargables and they are completely useless - drain extremely fast even when not in use.
I complained to Energiser - they tried to blame my charger and sent me some more batteries - the newer ones were no better than the old.
Unless you are going to use immediately after charging, avoid these batteries like the plague…
i have a few of these, they are rubbish, they hold charge for about 3 days then go flat very fast while not in use… i would avoid them, compared to the eneloops these are trash.
I have tried few different branded rechargeable batteries, but out of them i think Eneloop ones were the best
Just FYI, my experiences have been with vatara and powertech from Jaycar… they both seem to work pretty well… really like the powertechs

though they are more expensive than these…(just putting my 2 cents in)
the powertech is a 2A fast charger as well… been using the same batteries for years now.
I agree, with the Varta batteries
IMHO being able to charge them in 15mins is better then how long it take to go flat when not in use
Interesting feedback. I recall just before low self-discharge NiMHs hit the market, the Japan-made Energizer 2500mAH NiMHs were highly regarded, though I never liked them personally for similar reasons to those given here. Wonder if the Energizers have gotten worse, or if it's the contrast against LSD batteries making them seem worse.
As a general rule, the higher the capacity NiMh batteries, the quicker they self discharge.
that's a very bad generalisation, unless they specify LSD like sanyo eneloops or GP recyclo, the capacity doesn't determine whether they discharge quickly or not
Was not referring to LSD, as the above batteries are not. Not the only article on this subject.http://www.large-battery.com/ni-mh-battery-first-charge.html
It's not a generalisation - Sanyo (now Panasonic) say one of the reasons for reduced self discharge is the "improved separator". The separator in any battery occupies space, and does not add anything to the energy capacity of the battery (it's an insulator). More volume used for separator = less volume left for the energy-producing bits = lower capacity.
Here's the research paper:
http://www.eneloop.info/fileadmin/EDITORS/ENELOOP/ARTICLES/T…
Another reason is that thicker electrodes = more recharge cycles. Only the surface area of the electrode contributes to the energy of the battery. Thicker electrodes = less area of electrode that can be fitted into the battery = lower capacity.
These batteries are crap, my parents have had alot more success from the Sanyo Eneloops. Save your money and just buy the real deal the first time, Eneloops arent much dearer!
Edit: The old deal is active again so 8 Eneloops for $25 delivered. Assuming you want 8 these actually work out cheaper!

You should post this as a new deal.
Just 4?
