You cannot use a car battery in your mobility scooter as they are not meant to be constantly drained like a mobility scooter battery.
While you could install a car battery on your mobility scooter and make it move it will not work properly or last as long on a charge.
You want a deep cycle battery that is meant to be drained and then recharged constantly.
Car batteries are only meant to send enough power to start the engine and then charge right back up with the alternator.
Mobility scooter batteries are deep cycle batteries that are meant to run a motor and be drained and then later recharged.

Smaller mobility scooters have a range of around 10 to 15 miles while larger mobility scooters have a range of around 20 to 25 miles as long as the mobility scooter is fully charged and the battery is good.
As the battery on the mobility scooter ages and is used it loses it's range.
You cannot overcharge a scooter or mobility scooter battery as most scooter and mobility scooter battery chargers have an automatic cut off which detects when the battery is full charged and then stops charging the battery.
However if that cut off on the scooter or mobility scooters battery charger failed it could overcharge the battery so it's best to not leave the battery charger on the scooter or mobility scooter plugged in all the time.
However overnight is good enough to charge the battery on the scooter or mobility scooter.
You should not leave your mobility scooter on charge all the time as it's not really needed and can shorten the lifespan of the charger and sometimes the battery as well.

Also your weight and the batteries age can also affect the miles you can travel on the mobility scooter as well.
As the mobility scooters battery ages it can lose the range it can take the mobility scooter before it drains.

My Grandpas mobility scooter can usually go 25 miles and then it needs charged.
He had a cheaper version and smaller mobility scooter that could only go 10 miles before it needed a charge.
He drives his mobility scooter all over town and has no issues as long as the battery is fully charged.
