can a 12v lawn mower sealed battery be charged with 12v battery charger use on cars
no, if you charge 9 volt battery with 12 volt battery you will destroy 9 volt battery
No. The charger for a car battery has an output measured in amps. You have an output measured in milliamps. There are 1000 milliamps to 1 amp. Way too small.
Yes, but you cannot leave it for long periods of time or the battery will overheat and boil acid away. Normally a fully dead battery to a full battery should take about 2 hours to charge up at 40 amps.
Only if clean rainwater or distilled, and even then not very much. Just enough to cover plates, and charge immediately on long 2 amp charge.
All the light bulbs in your house are in parallel across the power line.All the devices plugged into a power strip are in parallel.Everything in your car that gets power from the 12V battery is in parallel.etc.
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.
If it is totally dead charge it for 2 hours at 10 amps.
To charge a 12v car battery,you need to increase 2v i.e 13-14v.More than that may cause damage to the battery.
Depends on the amperage of the charger. A 10 amp charger will charge it in about 1 hour.
The battery is a 12V car battery.
A good auto battery will hold it's charge for at least 6 months or longer.
Depends on the amperage you are applying to it. Read the charger manual.
I'm actually charging my 12V sealed lead acid battery with a laptop adapter which output is 19V, 2.1A. I'm not sure this will shorted the life of my battery or not, but the battery hold the charge. I don't have a voltmeter to test the voltage, but the battery can light up a 12V car headlight light bull. So, I guess it work.
As long as the battery in the lawnmower is a 12 Volt battery you will be fine.
Voltage is the same but amp hour capacity of the car battery is much higher.
Yes, you can do this.
Yes as long as it is the right voltage: a 6v battery needs a 6v charger; a 12v battery needs a 12v charger. <><><> If you can set the battery charger's output to give either a 6 or a 12 volt output, then you must always remember to set it to 6 volts if you want to use it to charge a 6 volt motorcycle car battery.
