If you leave a car running, why would it charge the battery? If anything it would deplete the battery. Just like in the real world. In order to charge the battery you either need to remove the battery and charge it up, or if the car has a "battery charger" function you would need to move the car in order to slightly charge the battery, since the mechanical movement is converted into power.
Physics is your friend.

The battery will charge as long as the car is running.
A car without a charged battery can't even start.

Hello Nordil, this is a forum about Project Zomboid - a game. Not Real life. Don't be confused by applying logic from IRL in PZ, it's irrelevant. :)
In PZ, an engine running charge the car battery regardless if the vehicle is moving or not.
The part about the battery charger is true tho. Only worth using if your battery is empty, usually (as your car won't start).

But that's how it is in real life.

Batteries lose charge when the engine isn't running, that's why leaving your headlights on or leaving the radio on for a long time without the car running will leave you with a nice surprise when you get back.

Heck, if you don't start your car for a long time, the battery will die on its own.

Well in real life....Your car while running WILL charge your car battery....i was wondering if this was impletmented in game as it DOES OCCUR in real life.

Just wanted to mention that I checked the charge on my car's battery and it was at 100% charge, and this car has been my daily driver for about 4 months now so, to answer your question, OP: probably.

On certain cars. But we are talking about 93. If i recall well this was not yet added into cars, i am not even sure that the "tire" charging was added.

Alternators in cars started to become standard equipment from 1960, never mind over three decades later.

Hi there alternator have been around for quite a long time.Thier purpose is to recharge battery while the car is tuned on.Pre alternator car had what was called back in time a dynamo which was working like an alternator but in a different way.

hm seems i learned something today as well, and i was wrong.
Thanks for sharing this all of you, and to the OP, it seems it was my mistake not knowing enopugh.

Side note because I just dealt with this today.

If your battery dies always have it tested before just replacing it (IRL)

The reason being if your alternator is out (and as such the battery did not charge while the vehicle was running) you wouldn't know because installing a new battery would still allow the car to start, because it would have a near full charge. Yet because your alternator is not working this battery will now drain until you are stuck again.

(PS. Why don't we have jumper cables in game??? Allow us to start a vehicle with a red battery if we jump if off a running vehicle with a battery over say... 80%? and remove some of the durability of the working battery as a trade-off!)

I heard you can charge your cars battery if you place a generator near it and then fuel it, or something, although you might need a car battery charger. Either way, your car just magically gets power to the battery if you're in a cell with power anyway, I think. It's even feasible to keep a cars headlights on at night if you have a generator working nearby, actually. I do know that turning your vehicle off and on as you make short stops is actually worse than just leaving it running though, because the car uses a small chunk of energy (maybe even durability) from the battery each time you start it up. I think the battery does charge over time when the car is running, but not sure if that's only when it's moving or just sitting idle.

I guess it's more about the fuel running down if you leave it running vs the battery dying if you start the car too many times in short succession really. If you're running on fumes you don't want to leave the car idling, plus you'd probably need to make like 20 sudden stops-and-starts in a row without driving around much and running the engine before your battery died anyway.

lol in-game tooltip gave us the answer.

While the tooltip is true I wouldn't trust any tooltip. I saw plenty of wrong one over the decade of gaming I'v done.
