I'm spending bike money on AA lithium batteries.....do the rechargeable batteries offer acceptable performance/economy?

I use them in my mouse and keyboard, so not a fair comparison. What camera still takes AA batts?

I use an older digital SLR...don't recall the brand, but it takes magnificent pics......
It eats batteries though.

For sure, the Everready rechargeables have a pretty good warranty too. Otherwise, go to Costco and buy a huge 40 count package of Duracell Coppertop AA's for $11.00-$15.00.

Also, every 5th flip I get these days comes with a computer, invariably no working battery. I buy the 2032 batteries in bulk on ebay for about $.50 each. They work elsewhere too, like some of the Knog lights.

I really hate the feeling I get when I have to throw Alkaline batteries in the trash, but of course, I still have to do it.
But for some things, I'm glad I bought rechargeable batteries. I think it's worth a try in your DSLR. You can always carry
a spare set as backup. Or even spare Alkalines as backup.

While scrap is created, at least the reformulated batteries no longer have cadmium and lead in them. That's why no more recycling drop offs for them. None of the "A" stuff you're worried about too.

Also, new cameras are pretty cheap at $59 and up.

lithium AAs are not cost effective or efficient use of their energy. The AA cell uses a resistor to bring down the voltage to match AA specs. A lithium cell's normal output is 3.7V.

Hi quality NiMH AAs should last a long time, and retain charge well. When buying, look for Japanese-made batteries. If the packaging states Made in Japan, they were likely OEMed by Sanyo
Sanyo cells are some of the best and most reliable.
Sanyo makes a line called Eneloop which retains their charge for a long time. Most discharge in storage.
look for cells with a 2500 mAh rating. Anything more is hype. Or will self discharge far sooner.

I agree with this post. I have some eneloop battteries, and I'm very happy with them. I have a few Eneloop XX batteries as well for high drain applications as well.

My camera also uses AA cells but I've never used the disposable alkaline or lithium ones in it. Decent NiMH rechargeables are good for hundreds of pictures per charge and can be recharged hundreds of times. The low self-discharge type (such as Eneloop and other 'pre-charged' models) are best if your camera will sometimes be sitting unused for extended periods. But they don't have quite as much capacity as the regular NiMH types. The pre-charged ones have a capacity of about 2000 mA-hrs vs. about 2500 mA-hrs for the regular NiMH cells.

Been using NimH since they came out, and I still use them in my Olympus Digital. I see no less performance from these batteries as I did from one use AAs. A good charger is a bit of an investment, but I only use NimH AAs and AAAs anymore, as well as 9v.

I use an xpal xp4000 that gives me at least 4 hours extra on my S4 and iphone its great value for about 20 Uk£s it also fits nicely on my triangle food bag on longer trips I use the xp18000 that gives about 5 days but is bigger in size will also run a laptop

As WNG says, Sanyo Eneloop. For long term use, I put them in the blinkies.
Also, Maha Powerex or their Imedion NiMH. Maha makes a great charger, the MH-C9000.

Shucks, my wife's Nikon Coolpix L810 using 4 AA batteries!!

4th'd. Eneloops are tough to beat. Great recycle time (like an alkaline) in a rechargeable battery.

Heres a video that shows my battery setup... https://www.youtube.com/watch?v=mR-hSLrgRQw
