The more amperes the battery has the better it is at starting your engine in cold temperatures. Also the larger the engine the more amperes is needed to turn it over.
The number of amperes is unrelated to the voltage. The maximum amount of current (in amperes) that you can take from the battery depends on the exact build of the battery.
12v , 7Ah means its the capicity of Battery , if load current is 1 amp then battery runs for 7 hrs. AH = Ampere* Current. 12v, 7ah 20hrs its shows load current is 7/20 amp.
Batteries are generally not listed as having watts. And there are a couple of different ampere ratings. But if you're running something needing 12W of a 12V battery it's pulling 1A out of the battery at the moment.
To charge a 12-volt battery, you need somewhat MORE than 12 volt. The 500 ma and the 6 amp are unrelated: battery capacity is often expressed in ampere-HOURS, which is not the same as amperes.
It depends on the Ampere Hour rating of the battery. But basically just connect as much as you wish but not more than 5 lamps and must be 12v each.
can a 12v lawn mower sealed battery be charged with 12v battery charger use on cars
The battery is a 12V car battery.
I have no idea what a normal household battery is. Generally you would have to match the current and voltage of the car battery and then you have the issue of how long the battery can sustain the current, or ampere hours.
No, you can not charge a 3V battery with 12V charger.
Probably - most ride ons are 12v the same as cars. Just check it is not an older 6v battery first - pull it out and read the label. If it is 12v, connect those leads and fire it up!
Anything needing 12V to operate.
In order to use the "plug in" pest control with a 12V battery, the device would have to have power requirements less than or equal to that which a 12V battery can provide. The pest control would also need an adapter to use the 12V battery.
