AGM Battery replacement?

clovisb31 · 2026-03-20T20:49:26+00:00

Hello, I'm thinking about replacing the OE flooded lead acid battery with an equivalent size AGM type battery. The Tacoma charging system provides 13.9 Volts to the stock OE battery. An AGM battery typically needs 14.4-14.6 volts to properly charge. Is the alternator/charging system voltage able to be changed/increased to allow for proper AGM charging? Does anyone know what the procedure is? Is a dealer level Scan tool required to do this modification? Thanks in advance.

It was about time! I should have taken them off day one, but I didn't hate the look when the truck was stock, and over the past couple of months with my lift, wheels, and tires. Definitely gives you more ground clearance, but I took them off in preparation for my Cali Raised Trail Edition rock sliders. More to come there soon!
