I suppose you're referring to a riding mower. As you didn't specify the age, make, etc, this will be an educated guess. If the mower is kept in a controlled environment, such as a garage with heat during the winter months, the battery should hold charge for years. If it is kept in a shed outside, then you'll probably need to charge the mower's battery every spring. All you need is a battery charger with jumper cables. Make sure it is capable of charging you're mower's battery.
The battery is charged by a generator or magneto. It is located under the flywheel.
Most lawnmower batteries will be badly abused by this and it will be quite expensive in gasoline. A lawnmower battery will normally take 8 hrs (or so) to charge. Forcing them to charge faster, like off your car, will harm it.
Yes.
Yes, it charges from the magneto.
The battery is kept charged by a generator or magneto when the engine is running. It is located under the flywheel.
can a 12v lawn mower sealed battery be charged with 12v battery charger use on cars
As long as the battery in the lawnmower is a 12 Volt battery you will be fine.
Answer Most of the time the battery is loosing charge on a mower it is bc the battery is going bad. The cells inside are wearing out and not holding a charge. Replace the battery and usually the problem stops. If it is a acid fillable battery then make sure the battery has the proper amount od distilled water and acid in it. Also if it is a serviceable battery then I would replace it with a maintenance free battery anyway. A lot less to mess with. Good luck.
Yes, if it will fit.
It is unlikely that the NB4L battery will work for your lawnmower but it really depends on your mower. Most of these batteries are used for small electronics like cell phones.
no. not good idea
You can buy a battery powered light at the bicycle shop.
Unless it is a rechargeable battery you cannot charge a dry charge battery. If it is rechargeable you need to purchase a charger for that size battery. Automobile batteries are not dry charge.
