5200mAh Li-Polymer Replacement Battery for JBL Xtreme 2, JBLXTREME2BLKAM, JBLXTREME2BLUAM Battery Fits 2INR19/66-2 SUN-INTE-103, CameronSino Li-ion 3.70V Battery

This battery does not last, I installed it and have not overcharged it at all and only stays charged with 1 light for half an hour. And then when it is plugged in, it shuts the speaker off after only reaching one light on the indicator. Started off good but lost longevity and battery life pretty quickly, ive only had it for like 4 or 5 months. Dont waste your money on this battery!
