Mighty Max BatteryMighty Max Battery 12V 7AH SLA Replacement Battery for ADT 477967 Brand Product

I bought this battery to be the heart of a portable power box for camping. I use it to charge my cell phone and other devices without draining my vehicle's battery. I tested it at the shop at work after I built it, charging a small power bank, my phone, my earbuds, and my cordless soldering iron all at once, and it handles the load for hours without issue.

Perfect fit, hook it up and your done! Can't get any easier than that.

The system had to charge it for a few days. It has been working well since then.

Battery died within 24hrs of install. Didn’t check before I installed to see if maybe it arrived that way.

Excellent value, fast delivery
