Worked great

### ⭐⭐⭐⭐⭐ Solid
*by A***. on January 8, 2024*

Saves you the hassle of buying new ones every time

### ⭐ Incorrect description, way below average capacity.
*by J***N on February 12, 2024*

First I wanted button top and that is what I ordered after returning the first set with a flat top I got this pair also not button top but I didn't feel like dealing with the return process again.But silly me should have graded them before using them, because the device in question lasted less than an hour before reporting the batteries drained. I have 5 year old lg batteries that are actually still 3200mAh, so I assumed these would be pretty close to their rating unlike the 9000mAh/etc ones which are obviously bogus/lying. As seen in the attached image both of them come out about 1660mAh or half of their rating.
