Best Rechargeable Batteries I've Ever Used!
I've been using the SPYONG USB Rechargeable AA Batteries for a few days now, and I’ve already recharged them multiple times. The quality is outstanding! I've tried many USB rechargeable AA batteries before, but these are by far the best.The 3450mWh capacity ensures long-lasting performance, and the convenience of the 4-in-1 USB-C charging cable is unmatched. Charging only takes 40 minutes, and the LED charge indicator makes it easy to know when they're ready. With over 1500 recharge cycles, these are built to last.If you're looking for reliable, high-quality rechargeable AA batteries, look no further. Highly recommended!

Useful
The batteries at home run out quickly since many of my child’s toys have music and lights, requiring batteries. I‘be switched to these rechargeable batteries, and they charge quickly, each battery can be charged individually. They do get a bit hot during charging, but once fully charged, everything works normally. They’re now working well.

Would give 4.75 stars if it would let me
9 out of 10 of them charge with the C-port. But I can charge the other one through my device. So to me it's still ok. But that is why I didn't give 5 stars. They work really great so far. I'm going to have to order more of them.

Las mejor hasta ahora
Muy practicas, se pueden cargar mediante puerto USB-C lo que las hace maravillosas, soportan mucho cada carga, y es de muchos ciclos

How do I get a replacement for a battery that won't recharge?
These AA USB rechargeable batteries have been good so far, but I am trying to recharge one of them and it just shows a red light or a blinking red light. It no longer holds a charge. How do I get it replaced? I purchase it in July 2024.
