My batteries were about 20% charged when I received them, so I topped them off before their first use with no problem. I’ve put them in a couple of low-use items—a flashlight and a TV remote—and so far, no issues.At 800 mAh, these batteries are probably better described as moderate capacity (as opposed to super capacity as in the description). There are much higher capacity rechargeable batteries on the market and you may want to check into one of them for your power-hungry devices.As of this writing, I’d say these rechargeable AAAs appear to be good, basic-use batteries. Time will tell how well/long they hold their charge and how long they will last.
