12 volt battery

A lantern battery is a rectangular battery, typically an alkaline or zinc-carbon primary battery, used primarily in flashlights or lanterns. Lantern batteries are physically larger and consequently offer higher capacity than the more common torch batteries. Lantern batteries comprise multiple cells inside a housing.
The most common variant in the US is the 6-volt square-base battery with spring terminals. In Europe the most common one is the 4.5-volt flat pack.

    Why have a 2 stage start button? First stage drains the 12v battery

    If you get time I would be interested to get your views on what value the 2 stage start button adds. I can’t see any value in using purely the 12v battery in the accessories part of this and I’ve spoken to a few people who’ve started to drain their 12v batteries in this setting. What’s the...

    When is the 12V battery recharged?

    I was just wondering when the 12V battery is recharged? Is it when the car is plugged in? Or when driving like the ICE cars? Or some other time? (maybe only when regen breaking?)

    Dead 12 volt battery

    Hi. Has anyone else experienced to have a dead car because the 12 volt battery is suddenly very low? We didn't use the car for 5 days, and when it was time to use it again, we couldn't open the car. Luckily I have seen a video on how to enter the car with the secret key. But everything was dead...

    12v battery level

    I've read in various places that the 12v battery gets charged up when you're charging the HV, is this so ? The reason I ask is, yesterday when I did my first home charge (top up) on my Pod Point the first thing I noticed was the 12v battery level was down a notch when I started the car. It had...
