What do you charge a lawn mower battery?

Not sure if the question is what to charge the battery with or how to charge the battery. So, I will address both: A regular battery charger can be used. IF you are going to purchase one, you really don't need a top-of-the-line, expensive charger. A simple 2 to 6 amp slow-trickle charger will do the job. To charge the battery, connect the red charger cable to the positive battery post and the black charger cable to the negative battery post, then turn on the charger until the battery is charged. If necessary, clean the battery posts and cables before charging. The battery charger will have more complete details for charging the battery.
