Power Max GT14B-4 Battery – SigmasTek Replacement, 12V Rechargeable SLA AGM

Need a replacement battery for a SigmasTek setup or something that takes a GT14B-4?

This Power Max is it.

It's a 12-volt, rechargeable SLA (sealed lead acid) AGM battery.

That means it's maintenance-free, spill-proof, and works in a bunch of different applications—alarm systems, backup power, maybe even some small vehicles or equipment.

It's a VRLA type, so it's valve-regulated.

Brand new, in the box.

Comes with a 6-month warranty.

One note: there's a Prop 65 warning, but that's standard for lead-acid batteries.

If your old one won't hold a charge, this is the drop-in replacement.
