Re: Couple Questions I can't find in Manual
That 12-volt battery is an "absorptive glass mat" type of sealed lead-acid battery. Its rated capacity is only 48 Ah (it powers only the electronics — it never has to crank the ICE). This type of lead-acid battery is chosen because it can take repeated deep discharges without damage (unlike regular lead-acid batteries), but it must be charged and discharged carefully at a controlled rate dependent on battery temperature, amongst other things. It has an internal temperature sensor (you'll see the connector near the + terminal), and an over-pressure venting pipe that runs to the outside of the car (also near the + terminal). It is custom made for Toyota, and should only be replaced by the same model.

Reason: Corrected Ah rating.
