Rechargeable AA Batteries, 2600mWh High Capacity 1.5V Lithium AA Batteries with 4-in-1 USB Charging Cable,1.5 Hours Quick Charge,1500 Cycles Long Lasting (4 Pack)

Very good batteries

I use these batteries for a doorbell camera

These are nice rechargeable AA lithium batteries. I like the way you can charge each battery individual without a dedicated charger. My only gripe is the batteries don't have a type c port (micro USB port instead).

bought to replace blink batteries have been working great

Batteries are battering just like they should so far!!

If you’re someone who chews through AA batteries quickly, this pack of Rechargeable AA Batteries is a fantastic solution that will save you money in the long run while reducing waste and benefiting the environment.Each pack includes eight batteries rated at 1.5V with a high capacity of 2600mWh. Although I haven't conducted a scientific capacity and discharge test due to the lack of equipment, these batteries seem to last just as long, if not longer, than name-brand 1.5V alkaline batteries. I’ve used them in various devices, including my Xbox controller, wireless walkie-talkie, and even my vintage Sony Walkman (yes, I still enjoy listening to cassettes from time to time).The pack comes with a convenient 4-in-1 USB charging cable. You can plug it into any USB-A port, such as a phone charger, power bank, or computer USB port. The other end of the cable splits into four micro USB plugs, allowing you to recharge each battery simultaneously. This concept is excellent, even though rechargeable AA batteries are not new. Most AA rechargeables use Ni-MH or Ni-CD chemistry, with a maximum voltage of only 1.2V when fully charged. Some devices struggle with this lower voltage, but these batteries maintain a steady 1.5V, ensuring maximum performance throughout their use.While I’ve only been using these batteries for about a month, which limits my ability to comment on their long-term life or degradation, I am optimistic about their durability. Given that they likely contain lithium cells, a typical lifecycle of 200 to 300 cycles can be expected.In summary, these rechargeable AA batteries provide an efficient, cost-effective, and environmentally friendly power solution. Whether you’re powering gaming controllers, communication devices, or nostalgic electronics, these batteries deliver reliable performance and convenient recharging capabilities.

Estoy probando el producto, así que no puedo dar un dato exacto

These batteries work great. You can charge each set of 4 all at once with the included USB splitters. They came in 2 packs of 4, with two 4-way charging cables. You do need to supply your own USB power. They didn't take very long to charge but hold up just as good as store bought brand name batteries. Great product all around. G score: 10 of 10
