    Wondering if anyone has tried switching to a 12V lithium aftermarket battery? I'm currently looking at this one:
    12V Lithium Battery for Toyota Prius | ohmmu.com

    I'm needing to replace the 12V battery on my 2017 Prius Prime Advanced, after having to jump start it about a dozen times. The NOCO - 1000A Lithium Jump Starter - GB40 has been very useful! Interested in switching to lithium as I use a dash cam with parking mode. I've also noticed recently that if you turn the car off but don't open the driver door, the headlights don't turn off!?

    True. I just quickly turn the stalk from Auto to Off and back to Auto. Done

    No experience with a 12V lithium aftermarket battery... But for more than 2x of the price of a regular lead-acid battery, do you really get twice the service time? If your OEM lasted ~5 years, that means it has to last more than 10 years to make it worth the cost. Let us know how it works if you buy one. Good luck.

    Don't do it. It is probably very dangerous. Rechargeable lithium batteries use special charging circuits, and they are typically not interchangeable with other types of rechargeable batteries. They are also a fire hazard even if they are compatible. You don't want a bomb under your hood that could go off in a minor collision.

    The capacity of this battery is 40 AH, the lead acid one I bought recently is 50 AH.

    LiFe batteries are not a fire hazard and several available models have built-in BMS to protect the battery during charging. They are, as noted, expensive, so the economics probably don't justify their use as a 12v replacement.

    Keep in mind that lithium batteries protect themselves by not allowing themselves to be charged at temperatures below freezing. So not a good choice as a auxiliary battery in colder climates.
