how long do i have to charge a lawn mower battery before i can use it
Step 8. Allow the correct amount of time for the battery to charge. Most chargers will take between 4 and 8 hours to charge a battery on trickle.. This is appropriate for a mower battery to prevent damage or explosion.tep 2. Disconnect the positive and negative cables from the battery. The mower battery will either have a cable end, like a car, or most will have a bolt that goes through the cable end and terminal to hold the cable on.
