Title: Short and disappointing life
Review: I purchased these batteries less than two years ago. The use of them was light - in a wireless keyboard. They have not been recharged anywhere near 300 times (maybe, *MAYBE* 20 times total) and are now showing an error after a few seconds of being placed in the Sony charger. They have not held a charge while out of the charger for more than a few days, which has left me relying on the purchase of regular batteries or twiddling my thumbs and waiting while these charge up again. I have since switched to a different brand of rechargeable batteries and am having no problems with those.I had the same type of experience with the AA version of these batteries as well - also used in a Sony charger.
Is the review positive or negative?
