### ⭐⭐⭐⭐⭐ Replacement batteries for ear buds
*by M***E on November 11, 2025*

Word as expected.

### ⭐⭐⭐⭐ Plug polarity are backwards.
*by D***E on October 5, 2024*

I love these batteries and use them in all my DIY projects. They are a lot cheaper getting through Amazon than from the manufacturer or China. The only issue I have with these batteries is the plus and minus are switched on the plug end. No matter as it's easy to swap the around but you need to be careful not to short the together. Great shelf life as well.
