4 Pack USB Rechargeable AA Batteries with 4 in 1 Charging Cable, 1.5V Lithium Double A Size Battery 1200mAh for Blink Camera Xbox

So conveneient. And holds charge for a long time. I use it for my XBOX and PS4 controllers. It comes with a nifty cable that charges 4 at a time.

All four of these batteries measured 1.5+ V right out of the box. I have now idea how long ago they were charged, probably several months. I randomly grabbed one and put a 20mA load across it. Two hours later it was still measuring 1.5+ V with the 20 mA load. Admittedly, 20 mA is light duty for a 1200 mAh battery, but it demonstrated that it continued to produce the claimed voltage after an extended period. Using the included cable, I charged them all, then disconnected them and 10 hours later they were all at a consistent 1.55V.

Nice batteries for ham or security cams that drain a lot of batteries. Amp hour could be higher.

They're good but not great for some reason in certain item they will not work. For example I have battery powered led Christmas lights and for some reason they will not power them on

They don't last long. You need to recharge them really often

The ONLY rechargeable batteries I’ve ever bought that work with all my items, including the ones like Blink cameras or WiFi water meters that claim they can’t take rechargeable batteries. So far, have had them in my Blink cameras for about 3.5 months and battery level still showing strong. Will be buying more

These are great for my lights in my windows. I keep them plugged in to a smart plug and I’ve had zero problems. I’ll get again.
