Rechargeable AA batteries and such

I've used lots of AA rechargeable batteries.. more Lithium Ion lately.

Who has experienced quick "fallout" of these batteries? Which are best in your experience/application?

If by "fallout" you mean becoming unusable, I have. Actually I have given up on aftermarket batteries. Usually the original ones that came with the device worked great. Any replacements were about 1/2 the life-and I'm careful about charge cycles. Most any device requiring batteries I now lean towards the one you can substitute alkaline in. :dunno Gary

Yeah... you would think the manufacturers would make batteries!!!:violin

For AA I've had best luck with Sanyo Eneloops. They are NiMH hybrid batteries that do not self discharge. A normal NiMH will be mostly dead after 6-8 weeks of sitting. The Eneloops will have 80% of their charge (or more) left after a full year of sitting. I've switched things like my camera stobe which isn't constantly in use to the Eneloops so there will be power when I need it. I've also some in AAA size for the headlamp that sits in my tank bag.

The Lithium has a higher voltage than NiMH. That may be important for some uses. Also, I don't think the Eneloops come in a capacity larger than 2000 mAh. That may not be enough juice for your use.
 
After years of using rechargeables, I have also given up on these. I buy Lithium for some equipment and Energizers batteries. The only rechargeable that I can count on are those that I use with my professional camera equipment.
 
Rechargeables

I am with Marchyman on this - Eneloops. They hold their charge.
The flashlight nerds over at the candlepowerforums.com are all gaga over them, too. I use them in any device that has to work after sitting for long periods (flashlights, for instance). I also use them in my digital cameras since they have a tendency to sit for extended periods of time.
Ritz camera usually has them, and candlepower has links to order them.
 
I gave up on AA and AAA rechargeable batteries years ago. This was mostly because they were one more thing to keep track of when I wasn't using them for a long period. For the money they cost and the amount I use them, I'd just as soon keep a supply of good quality lithium batteries handy. They have a shelf life of years, and I don't have to think about it.

For touring purposes, they also mean I don't have to carry a charger, and replacements can be had at any drug store while on the road.
 
Thanks Folks!

Looks like "good ole reliable" is still the best choice when I need flexibility and storage time... And the "recharge option" remains hassle and short lived.

No "news" there.... yet.

Wishing y'all a very blessed Christmas...
 
Stuff that goes on the road with AA or AAA gets ordinary batteries. We still use rechargeable batteries in several home-based devices. I have discovered that all batteries are not created equal. Look at the mah ratings - for AA I've recently seen them ranging from 800 to 2400. An 800 doesn't last very long in use in lots of things.

I've pretty much quit buying off-brand non-rechargeable batteries because I've had horrible luck (life) from the cheap ones. There have been some exceptions with house branded stuff from True Value or Ace but the no-name or new-name stuff from the dollar stores have been pure junk.

At my 50th birthday party (which lasted 3 days) some of the clownish attendees attached a little toy siren loudspeaker to the handlebars of my K75, along with the streamers and other adornments. After the party it went in a drawer in the garage. I rediscovered it last month. After 15 years it still operates. I felt compelled to see what batteries had lasted those 15 years. Energizer - not bulged or corroded and still enough to run the siren. YMMV. Don't try this at home boys and girls.
 
My wife , yesterday,drags out an "Elvis Presley" candy box that he sings to you when you open it & he has quit singing! It was my Mom's and came as a gift to her from some truck co in the past. Anyway, I put new Energizers-3- button cells in it last year w/fresh date and all and it had played for something like 10-15 yrs prior on no name batteries-now its dead again. Now, one of my engineer sons says the bunny batteries are better than the lower pricepoint Ray-o-vacs. Has the "king" finally died? I'm taking to shop to read the voltage!
I think this whole battery thing is a conspiracy to get our $. I have tried name brand, Big Lots, $ store, Ray-o-vac and they all eat my $$$! These yard lights my wife has all over(and their rechargeable batteries) are a part of that conspiracy! Proof I'm right:I spend more on batteries for Chinese junk than I do on a battery for my bike! :scratch
 
I've been using a set of 4 rechargables to run a small tape player and a portable CD player for several years, now. It seems as if they are not quite holding a charge as long as they used to, but vs. the way I was going through AA battreies, they've paid for themselves over at least twice. I'll post the brand when I get home.
 
I've been using Panasonic NiMH batteries for about 5 years.

Although I have two batches of those batteries, the older ones when I conditioned them on a Cadex charger, came back to 90% capacity and they've been recharged countless times in 5 years.

Whenever possible I try to buy devices that use AA batteries instead of proprietary batteries, otherwise you are carting numerous chargers along.
 
Casio watch battery

A little off the subject, but has anyone else experienced anything like this ?
In 1989 when we got married, my wife gave me a Casio watch that according
to the paperwork that came with it, had a 5 year battery in it. The strap on it
broke more than 10 years ago and I put it in my dresser. Every 6 months or so, I
look at it and can you believe that it is still running on the original battery ! It still
has the correct date but is about 15 minuets fast.
 
I have had the best all around luck with Energizer batteries. When I install them I usually write on them, with a Sharpie, the install date. A new twist that seems to be occurring is, for example, the flashlight going dim. Usually in what seems not enough on time for their use to be over. I have taken to testing each battery by itself and find one of the group has gone bad-less than 3/4 of a volt. I just replace one and I'm good to go. A good way to test them is with the Radio Shack meter #22-813. It's not a real precise meter but for quick all around use I can recommend it. HTH Gary
 
This was mostly because they were one more thing to keep track of when I wasn't using them for a long period.

It might depend upon how you define "long period". If you are talking about a flashlight that sits in a drawer for years on end then I agree... rechargeable may not be the way to go. On the other hand I don't find it unreasonable to charge a battery that's in occasional use once a year (or after heavy use).

The best "put in the device and forget about them" battery I've found so far are the Energizer Ultimate Lithium. These non chargeable batteries have a shelf life of 15 years or more. The perform well in both the hot and cold. They last a good long time when in use. They are more expensive than other batteries but you can sometimes find them on sale if you look around.

You can't have everything. :)
