Good replacement for lead acid gel battery.

I installed this in my Auto Battery Jumper when the original one died and it works just as well and should work longer because it's a lithium battery. An added bonus is that it's noticeably lighter.

Plenty of power

Bought a second battery also. Use is for a underwater light for fishing. Battery last and lasts.
