I bought these as a replacement for the disposable batteries in our remotes. They work just as well as the AA's I have for my camera flash. Long lasting and dependable.
I had been using Energizer rechargeable batteries, and was having problems with them not keeping their charge. It's the BEST charger and the batteries last longer than any other rechargeables that I've used. I bought the Sony batteries and charger and have had a great experience. I've recommended these to all of my friends.
Yes. I wish this was not the case, because I use my digital camera constantly, but rechargeable batteries burn of all their energy in as little as 30 to 45 minutes of (moderate) use, where a Lithium disposable might have lasted 3 to 4 hours. Using the Sony rechargeable batteries, I find I need to change batteries every 5 days or so. Obviously time varies from one set to another.My suggestion: Buy plenty of cells, and keep the charger handy, so you can rotate the batteries out with use. Have I had any trouble. I use it all day long.
They are fine for TV remotes or a wireless mouse perhaps, and other "light-duty" chores. You use it, and within a very short time, it's dead.FREQUENT CHANGESAn example: My wireless mouse. They simply do not last very long after a charge. Unfortunately, these batteries do not last long enough for heavy-use devices, such as digital cameras.
With a standard, non-rechargeable Lithium-type Energizer, I could use the same battery for 2 to 3 weeks or more. A solid, light duty long-term pony, in a race filled with short-sprint, high-performance thoroughbreds. Fortunately, with a rechargeable, I walk over to the charger, and swap it out (single battery mouse) but there is a noticeable difference in the life of the battery.NO REAL COMPLAINTSDo they work. ADJUST YOUR EXPECTATIONSThe very high quality standard disposable (non-rechargeable) Lithium batteries that can be purchased from Energizer and Duracell have set my expectations too high for these Sony batteries to compete with.
If you insist on trying to use them with a digital camera for your trip to Disney with the kids, I would advise taking along a large ziploc bag, with a full change-set of batteries for every 1-hour of anticipated use.VERDICT:Still a huge savings over time, and no real complaints other than the adjustment of expectations needed. No. Their individual charges appear to last 25-30% of the life of a disposable premium Lithium battery, so you'll probably be changing them 3 to 4 times more frequently.
These last longer than I expected and can keep up with my digital camera. I was so pleased with these that I bought the AA 2500 mAh NiMH batteries as well. I decided to go with an established name like Sony and I wasn't disappointed. With all the different names and types of rechargeables out there, I just couldn't decide which ones I should buy. I recommend both AAA 900 mAh and AA mAh NiMH batteries. I never run out of fresh batteries now since I keep a pair charged while I'm using the other pair. It still doesn't replace the alkaline batteries but do you really wanna keep buying those expensive batteries.
THEY ARE GOOD AT 900MAH BUT A1000MAH BATTERY IS BETTER
