I got this for an original life jacket. I knew ahead of time it would require me switching the position of two wires on the connector to work for the earlier model. That was not an issue and easily switched with a set of pin connector removers.The original battery was 4.800Ah and was manufactured in 2018. The fresh 5.200Ah replacement has my speaker playing through my entire 9hr day. It last longer now then when it was new.Thanks so much BatteryMart I really appreciate ya!

Turns out the device was the issue, not the Battery. I was extremely pleased they allowed a return. Very Professional. In the future I will use them for sure.
