Holds a charge very well perfect replacement battery for my flashlight 🔦

Works well

Product received in a timely manner and as advertised. Battery worked perfectly in my flashlight. Would buy again.

Charging well, keeping charge longer than my previous one. I’m using it in my bike front light

Had a flash light, I hadn't use in a year, ordered these batteries they work perfectly.

With a 9900 mAh rating I expected these batteries to be more than enough for a small LED flashlight. This was not the case. After charging and using them several times I found the longest each battery would last is about 5 minuets. Don’t waste your time and money with these.I would send them back if I could but by the time I was able to test them out several times with a full 2 hour charge in between my return period was over. Now to the trash they will go.

I guess I didn't read the description that close, because I was looking at the price and delivery date, which were both exceptional, so I was surprised that the 2-pack came with a USB charger which is great. I charged the batteries, and the brightness of my light seems appropriate, and I left one on for more than an hour and it seemed to maintain. So far so good.
