Obviously a lot of people are complaining about the ATV battery (and rightfully so imo) and some are even suggesting adding an alternator, myself included, even though that's not really how ATVs charge/maintain their batteries in real life.  However, if the battery didn't drain while you were driving around and only drained:

1. Every time you start the ATV

2. If you leave the lights on while the engine is off

It would act more like a real life ATV and I actually think the balance would be much better if not perfect.  It really doesn't make sense for the battery to be constantly draining while the engine is running but the mechanic of having to replace it (or recharge it at the base with a trickle charger, hopefully...) once in a while is sound.  At least until you get the solar upgrade.  If they really wanted to go full depth sim mode they could separate the "get on ATV" and "start engine" into different actions so you could leave the engine idling if you wanted to use the headlights while it's parked at the cost of some fuel.

Apologies if this has already been thought of or suggested, just my two cents!

If the battery on your AVT is dead, just take a wrench, remove the old battery and install a new one. Battery for car you can buy on store.

That's the problem; once the battery is dead, there's no way to use the ATV unless you buy another battery for 150 Points; which cuts almost your entire day profits in the early game. Fuel won't be a problem if you're able to use the ATV last effectively, the killer is the battery passively draining while driving it (Faster if you drive with headlights on).

In the discord the Dev looks to be adding in an actual Battery Charger for the ATV, so it should make it a bit better
