How Long To Charge A Lawn Mower Battery. This video from Sears PartsDirect shows how to charge the battery in your riding lawn mower. So make sure your lawnmower is definitely turned all the way OFF.
Some chargers shut off automatically when the battery reaches a full charge. Lawn mowers typically run on a 12-volt battery. I was able to find the instructions for charging the battery in the owners manual.
Once youve mowed half an acre of your lawn your battery should fully recharge in just 30-90 minutes depending on what brand you buy.
An average car battery has a capacity of around 48 amp hours which means that fully charged it delivers 1 amp for 48 hours 2 amps for 24 hours 8 amps for 6 hours and so on. Ideally you should use a battery charger to charge your riding mower battery because repeatedly jumping the battery can eventually damage the charging system. A lawn mower battery can accept around 500 charges with each charge lasting 45 minutes to 1 hour. Dry batteries charge much more quickly starting from half a day.
