Most lawn tractors possess one of two types of charging systems to help keep the battery up and running. One type of charging system is the belt-driven alternator, typically mounted on the engine. As the belt turns the alternator, the alternator continually generates power to recharge the battery.
Does a lawn mower charge its own battery?
Mowers are equipped with a battery that charges as the engine runs. If the battery has gone bad, it may not recharge at all, or may lose its charge very quickly. If this is the case, the battery will likely need to be replaced. You can test the voltage a battery is outputting by using a multimeter.
How do I know if my riding mower is charging my battery?
You should see a noticeable increase in the overall voltage reading at the battery when the engine is running. Starting and running the engine draws voltage from the battery and, once the engine is running at full throttle, the charging system compensates by sending voltage back to the battery to charge it.
How does a small engine charging system work?
The charging system is pretty simple, the engine has an alternator under the flywheel that puts AC volts into the Voltage Regulator, the regulator changes it to DC volts and regulates the output, the output goes to the battery via a wire that may go through a relay and fuse.
How long should you charge a lawn mower battery?

Read the meter. If it has 12.7 DC volts or higher, the battery is good and something else is causing your starting problem. If the voltage reading is lower, the battery is discharged to some degree but may perk up after charging. If it reads 11.5 volts or lower, the battery is most likely sulfated and needs replacing.
How does a Briggs and Stratton charge the battery?
The charging system for the Briggs and Stratton engine begins with the battery, which supplies voltage to the starter. Once the engine runs, the alternator takes over the electrical delivery, supplying voltage to the spark plug and sending extra current to the battery for recharging.
How long do I need to run my car to charge the battery?
If your car does start, let it run for a few minutes to help charge the battery further. Unhook the clamps in the reverse order of how you put them on. Be sure to drive your car for about 30 minutes before stopping again so the battery can continue to charge. Otherwise, you might need another jump start.
Does revving the engine charge the battery?
Does Revving the Engine Charge Your Battery Faster? The short answer is yes. … Revving the engine will charge the battery faster because the alternator increases this amperage. When you rev the engine, the alternator begins to run faster, which helps charge the battery.
