"PRE-CHARGED" Rechargable Batteries
"PRE-CHARGED" Rechargeable batteries NEED TO BE CHARGED before first use. There IS a difference and a reason whey they are labeled "PRE-CHARGED". Those labeled Pre-Charged indicates a rechargeable battery that once fully charged, will hold and retain that charge for a long time (months) if not used, and can be then used at any time without needed to charge them. If not labeled "Pre-Charged" they are a different kind of battery, which once fully charged, will only remain at that fully charged ...View full Review
"PRE-CHARGED" Rechargeable batteries NEED TO BE CHARGED before first use. There IS a difference and a reason whey they are labeled "PRE-CHARGED". Those labeled Pre-Charged indicates a rechargeable battery that once fully charged, will hold and retain that charge for a long time (months) if not used, and can be then used at any time without needed to charge them. If not labeled "Pre-Charged" they are a different kind of battery, which once fully charged, will only remain at that fully charged state and ready for immediate use only for A SHORT PERIOD OF TIME. Otherwise, if not labeled "pre-charged", you will have to fully charge just before actual use. It depends on what you are using the batteries for. If you plan to use and swap out frequently, they you might not want the 'pre-charged'. If you want to use in a MP3 player (for example) which you use only now an then, you would want the "pre-charged" so that you can leave the battery in the device, and when you come back and use it (days, months) the charge will not be depleted due to the lapse of time not being used. Non-pre-charged will not hold the charge very long if not in use.

Good theory, poor practice
After the first 4-5 cycles, these don't hold their charge at all, even for such low-intensity uses as keyboards and mice. I got a set of these about 8 months ago, with Sony's charger and they turned out to be a major disappointment. Will not buy them again.

After a few recharges, the capacity dropped fast. One dropped all the way down to 678 mAH Tried the refresh function on the charger a few times but never got close to the 2000 mAH stated on the package. Not the Sony quality that I expected.
Ordered 4 units, received 1. Remainder was canelled without reason or notification. Last time for ordering from Adorama.
Good, reliable batteries, good for clock, digital weigh balance, remote control, shaver.
Its a very durable high quality battery from Sony . Which last long , really long
My original purchase was identified as an 8 pack. When it arrived as a 12 pack for the same price, I was pleasantly surprised. Excellent service from Adorama, as usual. I haven't used the batteries yet, but I expect as a Sony product they will be fine. They don't expire until 2017.
I assume that the batteries work like batteries normally do. I purchased two 8 packs at an extremely good price which turned out to be an inadvertant price mistake. Adorama instead sent one 12 pack for what I had expected to pay for a single 8 pack, and honestly explained what had occured. You can't beat that.
I always like these batteries because they are durable. I used it for my 580EXII, it holds up to 300-500 pics which I am very pleased.
These Are Long lasting batteries they last for like 3 months when others barly last 2 weeks
I have used this to charge and restore some 20 AA and AAA size NiMH batteries and they are all working very well (some of them have not been used since 2009) after the charge. With the price I paid I am very satisfy with its performance.
I mostly use Sony AA NiMH for my Canon flash. It never fails me. Great product.
