What Agm battery should I get

[grantking2256]

Only using abt 800 watts for my amps

I have a ford focus sedan 2012. Not sure what my stock battery specs are and not sure which agm or exactly what an agm is really. Just going off a recommendation. Help?

AGM batteries are sealed, and have glass matt inside.

They charge and discharge faster than conventional lead-acid batteries.

XS power is a big name, but not always necessary, especially for less than 1k RMS.

The biggest AGM battery you can fit in your car should be fine. Brands don't matter very much. I run Exide, which is a rebadged AGM. Duracell is the Sam's club one.

Just don't get a new optima. There's a big thread on CACO about how they are garbage

I personally run Dekas. I can get them dirt cheap here locally and hold up quite well.

A diehard platinum sounds like it might fit the bill.

They are reasonable and there will be a sears everywhere, in case of warranty.
