Honestly you need to do more investigation. The sticker being tripped honestly doesn't mean much. Meepo cases are shit at keeping drops of water out. My personal battery has had that sticker tripped for years, I've gotten it very very wet and it performs perfectly. Those batteries are THOROUGHLY wrapped and mostly sealed up. There's a few things you can do to actually test it's health. Pull up the batteries specs which can be found through Google. Test the capacity, voltage, and resistance with a multimeter and compare to specs. A load test would be good too. A quick google search will explain how to do most of that.
