4 Pack 3700mWh AA Lithium Rechargeable Batteries for Blink Outdoor Camera

These rechargeable AA batteries work very well and last a long time. The constant 1.5V output keeps my devices running smoothly, especially for cameras and other electronics. They charge quickly and hold power much better than regular rechargeable batteries I used before. The included 12-slot charger is very convenient and makes charging multiple batteries at once easy. Everything feels well made and reliable. Overall, this is a great battery set with good performance and excellent value. Very happy with this purchase and would definitely buy again.

These batteries hold a charge and are true 1.5V unlike the other rechargeable batteries that are only 1.2V. These worked fine until 1 battery stopped charging along with one charging slot in the charger. I contacted the seller and they responded within 2 days. A new 4 pack of batteries was received within 7 days and a new charging unit is on the way. I'm very happy with the product and even happier with the service. I will buy more when needed.

I’m really impressed with these rechargeable AA lithium batteries and charger set! The batteries hold a strong, consistent charge and last much longer than regular rechargeable ones I’ve tried before. I’ve been using them for devices kids toys and household electronics, and the performance has been excellent. The charger is also very convenient with multiple slots, making it easy to charge several batteries at once. Everything feels high quality and well-made. I love that they’re rechargeable, which saves money in the long run and is more eco-friendly. Overall, a fantastic purchase—highly recommend!

I picked up these rechargeable AA lithium batteries with the charger, and they’ve been working great for my setup. I’m using them in a smart lock and smoke detectors, and they’ve been reliable so far. They hold a charge well and save me from constantly swapping out disposable batteries. The charger is simple to use, and it’s nice having everything in one package instead of buying pieces separately. Overall, they’ve been a solid upgrade from regular batteries. Convenient, cost-effective over time, and they just work.

Bought mainly for deep freeze temperature alarm. Seems good, although one of the batteries failed after it's first use.

This is the coolest rechargeable battery pack with charger that I’ve ever seen. It works great. The battery life is perfect. It shows when it’s charged. There’s a battery indicator light charges up super fast and cheaper than buying even a six pack of rechargeables. It’s absolutely perfectly compatible for the blink cameras set of 5 cameras.

Works great for rechargeable batteries.

After the first charge one if the batteries went junk. I have charged the other ones about 4 times with no other issues.
