What keeps the battery charged on a John Deere riding mower?
The John Deere L100 lawnmower runs a 12-volt system; the battery on any machinery needs a voltage regulator to keep the battery charged. When the lawnmower is running, the battery runs all the electrical components and the voltage rectifier sends 14-volts back to the battery to keep the lawnmower operating.
