You should attach a trickle charger otherwise that new battery will go soon too.
good to hear, but I’d suggest checking resting voltage a couple hours after driving. Make sure it’s keeping the 12V properly charged - otherwise you’ll prematurely kill the new battery.
If my Voltage reads 14.3 would it be safe to assume that the alternator is charging the 12v battery?

The purpose of my suggestion is that if you leave any car sitting for a long periods of time especially during cold temperatures the battery will drain.

yes, though the hybrids without 4th AUX switch don’t have alternators and the charging comes from the hybrid battery system.

key though is the battery voltage a couple hours after you’ve last driven. Fully charged should be 12.8V or so.

Yes, all vehicle in the past three+ decades have some level of parasitic draw.

If they keep their battery fully charged and don’t have excessive draw, they can sit for a reasonable period without weeding a trickle charger.

…If I already owned one with this problem, and got this BS from Toyota, I’d get an assessment from a properly certified independent mechanic and start Lemon Law proceedings.
…When guys claim to their wives & gfs they don’t do drama. But they do, they get their panties twisted over a DC-DC converter that refuses to overload a lead acid battery that sits in the cabin 🤏🏽 😆

Are you suggesting Toyota intentionally only half charges the 12V sealed lead acid battery because it’s in the pax compartment, thereby guaranteeing early battery failure as well as creating issues for people who might leave their truck a couple weeks?

That seems like a pretty stupid design decision Instead of simply putting the battery under the hood as with every other vehicle.

Do explain how it makes sense to do that?

No I’m suggesting you stop the bitching and upgrade your OEM shit which is clearly not cutting it for your drive schedule of 10mi/month and get with the times and upgrade that one-size-fits-all Ned Flanders starter battery to something that can handle sitting a long ass time. Get something like an Odyssey X-AGM24F Battery and enjoy life for a change 🤙🏼

Bitching in the direction of Toyota Corporate on a free website hunting for lawyers over a lemon law about letting your truck sit for weeks without disconnecting the battery. This is some funny shit, I think there’s a bunch of privileged 1st world gerrys with nothing better to do but bitch about their OEM battery. I couldnt help myself. Barring you had a defunct battery that got swapped, clamoring on and on about how bad Toyota engineering is really fking laughable. Go fking design a better rig.

Now if you’d excuse me, I’ll see my way out & never come back into this thread. Enjoy all
