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.

Hey fam,

I never got a chance to show you guys the taco stock. I love every upgrade I have done and highly recommend all MODs that I do, but this truck came perfect stock. This is my second taco and hands down by far Toyota has improved the Tacoma in every which way. Stock or modified, this is truck is a beast!
