Battery under the rear seat

Does anyone know anything about a battery that is located under the rear seat on a hybrid model. While trying to install rear seat covers, i saw it. when I removed the 3 locking plastic gadgets, I saw a battery there. The truck at the dealer now so I don't know if that is the primary battery or is that a second battery. It looked just like a regular battery to me, but let me admit I don't know what a hybrid battery looks like either. Anyone?

 

I’m pretty sure that’s the high voltage hybrid battery under the rear seat. What I read is that the hybrid format have storage under the rear seat(s), so that would confirm.

 

2 batteries, the HV battery is on the passenger side, the 12v battery is on the drivers side.

Treat the 12v battery like any other battery. Leave the passenger side alone.

 

I stayed away from it but it certainly looked like a regular car battery in terms of size and shape.

 

Yup it is, it will be a pain to swap out one day, but there's nothing to be afraid of, except the price.

Sealed AGM batteries are 400$

 

Is it a common size like we are used to (24F, 27F), or a unique Toyota only one?

 

So the battery is not under the hood? How do you jump these things if it is??? Thanks!

 

Use the jump post under the hood.


Edit....looks like the hid it:

 

Thank you very much! I assume the normal battery (not talking about the hybrid battery) under the seat is sealed so we don’t have to put water in it????

 

Unsure but assume it is the same as my sealed one in my non hybrid.

 

Thank you very much!!!
