Sony AA 2500 mAh Ni-MH Rechargeable Batteries In Slide Case (4-Pack)

These are great rechargeable batteries. I just wore out my first sets after 3.5 years of continual use in my digital camera. I didn't count how many times I recharged them, but it was a lot, and if I consider the cost of these batteries vs. what I'd have spent on alkaline in the time, not to mention the waste. I haven't seen other rechargeable batteries that I've felt would last any longer, so I'm buying another set to get me through the next 3.5 years.

It did not hold the charge for long. Bad quality battery from Sony.I was so mad I throw them away.

I do a lot of instrumental music recording and performing, and I use these Sony rechargeables EXCLUSIVELY in my gear, the most power-hungry of which are my Zoom H2 Handy Portable Stereo Recorder and my GigLight Compact LED Music Stand Light. I also use them in my Canon PowerShot A720IS 8MP Digital Camera with 6x Optical Image Stabilized Zoom when going "optical" rather than "audible."

I can EASILY record two hours of music on my H2 with two of these batteries at 44.1kHz, 16-bit. I have never even come close to their running out early, and I've never had the device quit because of a lack of power. And I have recharged these MANY times for MANY gigs.

Loading my GigLight with these, I have found I can run it OVERNIGHT -- even 24 hours! -- and not drain them completely.

Plus, the batteries last between 200-400 pictures in my Canon, depending on whether I'm using a lot of flash and whether or not I leave the AF on "continuous." I'm never short of power. It's amazing.

Charge time is very reasonable, and this handy carry-case (while the key ring is a bit ambitious) keeps my batteries together when I use the H2, which uses only 2, but keeps a spare pair at the ready if I need them.

These leave Alkis in the dust! HIGHLY recommended -- and that's high praise because I'm generally NOT a Sony fan. But I am a fan of these!

I have ordered enough of these batteries to use in everything requiring
AA batteries around the house and for my camera equipment (about 52). They will pay for themselves in 2 years. I should not need any more for many years. I like the slide pack for storing the charged batteries until I need them (great safety feature)

I love everything about these rechargeables. They seem to have exceptionally great capacity- I can drop these in my 580EX II and easily shoot an entire wedding and reception without changing batteries. The functional carrying case is a nice, handy bonus.
