Excellent Battery Replacement for my Rii Controller, Fits and Performs Perfectly!
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.
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.

The best of bad options.
They're not very good but they're the best I've found so far. I've tried several of this battery type from multiple different manufacturers.To that end, I'm convinced there are no high quality manufacturers for this type of battery. I suppose I'll be stuck with these for now.

When to charge
When my headphones went dead, I had a feeling that it was the battery and was right. They immediately started working when putting this battery in. I also learned that the battery should be discharged/charged between 20%-80%. With my headphones on and pairing them to my smartphone, my phone immediately shows me the percentage of charge.
