XS Power XP750 750 Amp AGM Secondary Battery with M6 Terminal Hardware - 12 Volt 22Ah 750CA Deep Cycle AGM Powercell for Car Audio Stereo Systems - 14.5 lbs, Maintenance Free, Sealed Design

A good upgrade to my eight year old 550 ah agm battery.

Powerful, way cheaper than other places, and seems to be lasting

Good for the price

Small easy to hide away in a small spot don't know why but my truck is starting much better now 😅 got agm up front and this one next to my amps no more going below 12v if you got the space and the money go for the external battery

Battery is ok. I think AGMs are decent for underhood applications, but they are pretty much pointless in large sound systems. I switched to lithium and haven’t looked back. AGMs are a pain especially if you are running multiple because you will need isolators.

Nice little battery 🔋 👌😎👍

I bought this battery and everything was good for a week. After a week this battery must have shorted out or something because it went from fully charged to 0.00 volts and now will not charge past 0.05 volts.

Nice little battery holds its voltage
