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.
No, it is not necessary to remove it. You can charge it right there on the mower.
replace it
Not at all. A 35 amp charger is far too large to charge a lawn mower battery. Use a 10 amp automatic charger.
yes as long as it is not totally dead.
NO You have to many AMPS from a car, you can jump start it butdon't charge it.
Do you mean that you can not charge it with a battery charger or the mower will not charge it while it is running? If you can not charge it with a battery charger and you are sure that the charger works then the battery is bad. These type batteries are only good for a couple years. If the mower is not charging the battery it could be a number of things.
I'm assuming its a riding lawn mower of some type. Our own lawn mowers of this type have an alternator in them that keeps the battery charged
dead & needs replaced.....
The lawn mower should charge its own battery as it runs. They have a charging system built in them on the underside of the flywheel. If it's not charging you may have to charge it every time depending on whether you use lights or electric clutch or any other electrical item..
can a 12v lawn mower sealed battery be charged with 12v battery charger use on cars
Provided the charging system on the mower engine is operational, a small amount of charging voltage will be supplied to the battery during use.
Depends on the output of the charger which you did not list. A dead battery can be recharged with a 10 amp charger in 3 hours.
