### ⭐⭐⭐⭐⭐ Excellent Battery Replacement for my Rii Controller, Fits and Performs Perfectly!
*by C***. on January 24, 2025*

This BL-5B battery is an excellent replacement for my Rii controller, and I couldn't be happier with it. Finding a compatible battery for this was a bit tricky, but this one fit perfectly without any issues. It charges just as efficiently as the original, and the best part is that it has a slightly higher mAh, which means it lasts even longer. I no longer have to worry about my controller's battery, giving me peace of mind as well. If you're in need of a BL-5B replacement, this is a fantastic option! Highly recommended.

### ⭐⭐⭐ May not last long.
*by R***K on February 26, 2025*

This battery arrived with 0% charge, which probably indicates that it’s old stock, not well-maintained, or poor quality.Typically, you don’t want to store lithium batteries under about 20% charge (I think it’s 20%). This arrived completely dead, and I had to charge it overnight before I started using it. That probably means his battery is only going to last a year or two before it starts losing its total capacity (it probably already has, but I don’t have a way of measuring it other than seeing how long it takes for the battery to die into normal usage).The other battery I ordered, slightly different size, arrived with around 50-75% charge, which is what I would expect.It’s not worth it to me to return or exchange this battery, but I just wanted to know that for anyone who needs one of these for long-term use.
