I've been using Rayovac Hybrid NiMh 2100Mah batteries for a couple of months
now. These are the ones that come fully charged in the package when you buy
them. They claim to have 4 times less leakage than typical NiMh batteries.
Previously I had been using Energizer 2500Mah batteries that seem to leak
down pretty fast when not in use.

I use my batteries almost everyday and always carry a spare freshly charged
set. I usually wear out a set of Energizers in two weeks to a month. When I
change to the spare set it seems that the previously charged batteries have
leaked considerable charge. This is not the case with the new Hybrid
batteries.

I find that even though the Hybrids are rated at lower capacity than the
Energizers the Hybrids actually last longer in my usage situation.

Now all we need is higher capacity Hybrids!

Or Li-Ion


The subject is rechargeable AA's. I've been using a set of Sanyo
Eneloops since last September, only charged once. These are excellent.
Hybrid type are licensed from Sanyo but their rating is not same.
Eneloop claim to keep 85% of their charge for a year, Hybrid 3 months. I
think either way this is much better than other NiMH's. Hybrids costs
less in Walmart, haven't seen them selling Eneloop, got mine for Ritz.

I hope you'll forgive me for being such an idiot. I read the OP eight
times and I did not see AA in there once.

I'm familiar with the claims for 'enerloop'. Perhaps you could enlighten
me though. As far as I know, the term 'hybrid' implies a merging of two
technologies e.g. a hybrid car is basically a 'gasoline-electric' - it
uses the small gasoline motor to charge the batteries. What is the
'hybrid' part here - NiMH and . . .?

What is 'hybrid' here is the functionality .. you get most of the
performance of NiHM (slightly less capacity, but same voltage, same
re-charger can be used, etc.) with something approaching the shelf life
of an Alkaline cell (well, 'somewhat in that direction' anyway), and you
can actually buy them charged (a non-starter with most NiMH batteries,
since they drain themselves on the self before you buy them).

I'd agree it ain't a great name though, since you don't get there by
crossing a Duracell with an NiMH cell and sorting through the offspring.

well, I think he was alluding to the fact that there aren't any rechargeable
Lithium Ion batteries such as the eneloops and Rayovac hybrids that come in
the AA format. However, you would have had to have been looking for AA
batteries to know that Lithium Ion ones are missing from the rechargeable
lineup.

I purchased several packs of Rayovac Hybrids in January. I have some of
them in use in two cameras and they are still on the factory charge.
The longer shelf life corrects the biggest complaint I've had about Ni-mh
cells. If you go between charges longer than 2 or three weeks these
batteries make sense. Price is right too. Under $9 for a 4 pack of AAs
(Hybrids at Walmart).

I got mine at REI in Dallas. I could never find them at local Wal-Mart
stores.

I picked up a couple packages, had a $5 off coupon from the newspaper
a couple months ago.... just started using them. So far so good,
started out charged.

I hope they stay that way, always nice to grab the camera for that
special shot, and have the batteries charged and ready to go. Not
always the case with regular rechargables.

These hybrids will soon obsolete all other rechargeables. Walmart has
a good deal on Rayovac hybrids.

I'm using 2100 mAHr 'Instant' which are pretty much the same thing (and
which came from the same place as my normal 2700 mAHr VapExTech .. i.e.
on line), and I get pretty much the same result. They're certainly the
battery of choice for the backup set I carry round the hills in case my
GPS (Or heaven forbid, my MP3 player) goes flat miles from home.

More (real) mAHrs would always be nice, but it's pretty much a mythical
number anyway, unless you are stuffing cells straight from the charger
into something you then use continuously until they go flat (and even
then, current draw makes a big difference).


I think I would be more concerned with my GPS batteries. A dead MP3
player isn't likely to get you LOST.

That is what the batteries mentioned by the OP ARE. You might read up
on the subject so you can follow the discussion.

Li-ion are ok if you only pick up the camera infrequently, or you're going
on a trip where you'll be away from a source of electricity for a period of
time. Other than that, it's just throwing money down the drain as far as
I'm concerned. While I'm not an earth-hugger, yes there is an environmental
concern with disposable batteries. They cost about the same as they
hybrids, so the only additional cost with hybrids is a good charger.

"Hybrid" means whatever the marketing department wants it to mean.

If you drive you know that there is "synthetic oil". What you probably
don't know is that most synthetic oil isn't synthetic. The marketing
guys for companies that didn't know how to produce it started calling
their top grade oil "synthetic" and Mobil wasn't fast enough off the
mark or hired the world's most incompetent law firm or something and
lost the lawsuit that would have put a stop to that particular deceptive
advertising.
