Does any one know if the PIP has the same OEM battery as the regular prius with smart key system. The part number is S46B24R. I am considering immediately upgrading to a Optima yellow top. The OEM PIP battery appears to have discharge problems possibly from not running the ice enough to keep it fully charged. I do not have the car yet but I have been reading the related post. I also intend on immediately upgrading the non JBL stereo with a 900 watt amp and new speakers. Hopefully the upgraded battery will reduce the stress on the 12 volt electrical system.
Well the inverter does when the HSD is at the "Ready" state. The ICE does not have to be running to charge the 12V Accessory battery.
I don't know, what kind of battery is on your car? with this info you can then check the Prius Generation 1-2-3 archives. Patrick Wong has stated the exact total specs and ID info on the Prius 12 Volt batteries. :cheer2: PIP Battery may be listed in owners manual on PC.
