Depending on the mower some have belt driven generator . But most have a alternator under the fly wheel . It might also be a faulty rectifier.
Hope this helps.
Mower has a generator, which is turned by the engine. When engine is running, generator produces electricity to charge the storage battery.
Dead cell in battery, loose of corroded battery connections, or the charging system on the mower engine is defective.
the same way a car
To start an electric lawn mower, first ensure it is plugged in or has a charged battery. Then, press and hold the safety button or lever while simultaneously pulling the start lever or pushing the start button. Release the safety button once the mower is running.

can a 12v lawn mower sealed battery be charged with 12v battery charger use on cars
Do you mean that you can not charge it with a battery charger or the mower will not charge it while it is running? If you can not charge it with a battery charger and you are sure that the charger works then the battery is bad. These type batteries are only good for a couple years. If the mower is not charging the battery it could be a number of things.
There is a charging system that is under the flywheel. It is a magnetto system.
I'm assuming its a riding lawn mower of some type. Our own lawn mowers of this type have an alternator in them that keeps the battery charged
A battery float charger is intended only to keep a fully charged battery from losing its charge. It will NOT work to charge a battery that is discharged or damaged. Check the voltage of the battery to be charged. Do not use charger if the battery voltage is less than 9.6 volts.
Yes, but it takes a very, very long time. The charging system on the riding mower is very low amperage. You would do much better charging it with a battery charger.
I suppose you're referring to a riding mower. As you didn't specify the age, make, etc, this will be an educated guess. If the mower is kept in a controlled environment, such as a garage with heat during the winter months, the battery should hold charge for years. If it is kept in a shed outside, then you'll probably need to charge the mower's battery every spring. All you need is a battery charger with jumper cables. Make sure it is capable of charging you're mower's battery. The battery is charged by a generator or magneto. It is located under the flywheel.
