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.

Hi Group,
I’m 64 and this is my first Tacoma. I’ve had 3 4Runners. (99,05,09). I love this ride. I want to add some more aggressive A/T tires but concerned how they will perform in snow and ice. Thanks for allowing me to folow
