2024 TRD Pro Battery Type

[Tom Sellick]

Did anyone ever solve the question as to whether the battery in the hybrids is an AGM type or other? I seem to remember reading differing thoughts here. Flooded? AGM?

Are you talking about the high-voltage battery for the hybrid system? It's a NiHM.

No sorry the 12V.

I’m pretty sure the consensus is that it’s not AGM but I haven’t learned much about batteries yet, I’m just happy my truck started after sitting for a week and a half

Ok thanks. I've got a new battery maintainer coming and it has different modes (wet cell, agm and lithium). Just trying to figure out which one is the right one.

I put my older maintainer on it today. Said it was 12.2v. Just got back from driving it and drive it everyday. Seems low but really not sure.

The battery does hover a bit low from normal gas models. Something to do with needing to keep a buffer and that it tends to run off the hybrid battery most of the time via the inverter.
I am not saying I understand it, I’m just saying what I’ve found/seen.

Pb means lead. On the left it says Sulfuric acid.
Ergo you are correct this is the Standard Lead acid battery not AGM

Sounds good!

That must be it. And not even the Toyota dealership seems to understand it!

You expect “Factory Trained Technicians” to know anything? We used to have mechanics that did know everything. Some manufacturers are using Lithium for the 12v Ford pickups is one. But it will be a cold day in hell when I use lithium due to fire hazard.

That is low. If you're getting the voltage from the maintainer, try it with a multimeter.

My 12V is always at 12.2 volts or below. That seems to be pretty normal for the hybrids, but I don't understand why it won't eventually kill the battery keeping it at suck a low state of charge.

Be interesting to see what a new battery would do.

Yep. My truck will be going to the dealer in a few weeks for service and I will see what they will do.

Whenever I replace the battery I will put in a yellow top Optima AGM, but hopefully they will replace this one. If it only keeps it charged to 12.2 volts I don't expect a regular battery to last very long.

Interesting. I’ll keep the Optima in mind. Let us know what happens.
