Battery is good, connector was wrong.
I purchased the battery because it was the size I needed. I wasn’t sure about the connector because it is hard to tell in the picture. I needed to replace the battery in my electric skateboards remote. I was able to unsolder the old connector and put it on the new battery with no issues. It has been working great so far! ... show more

THIS IS NOT A 400MA BATTERY
ZERO Rating --- This battery is NOT a 400ma battery. I first noted its small size when I opened the package. After 4 testing cycles it tests to a 200-210ma battery, half of the advertised value. Just because it is stamped 400ma on the battery, does not guarantee that it is. Not even close... this fraud. Stay away ... show more

Perfect lightweight batteries for Arduino projects!
I have some small arduino projects that utilize seeduino xiao microcontrollers with these batteries to power them and they charge well, last a good while. As long as you have a means to properly regulate the charging power to them, they'll last you a while and do exactly what you need.

Doesn't last very long.
The original 350 mah battery in my Bluetooth mouse was lasting a day before needing a charge. This battery was labeled 400mah and could fit so I put it in. After 4 months it needs a charge every other day a lot shorter than the original which lasted a week or two when new. I doubt it ever delivered 400 mah. ... show more
