apparently 24 hrs
Yes, as long as you do not overcharge it.
Depends on the amperage of the charger. A 10 amp charger will charge it in about 1 hour.
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.
Depends how flat it is and the capacity of the charger and also capacity of the battery. A 6 volt battery fully charged should read about 6.5 to 7 volts when fully charged.
In 24 hours it will be charged enough to start the car. You really need a much larger charger for a car battery.
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.
How long it takes to charge any battery depends on how much electrical charge it can hold. The physical size of a battery can give an indication of how much charge it may hold: the larger the battery, the more electrical charge it is likely to be able to hold. or you could just divide the mAh of the battery by the output rate of the charger. ex: 5000 mAh on a 3000 milliamp output charger would be 1hr 36min. and 3300 mAh on the same charger would be 1hr 10min. and so on.
Probably need a new alternator, or you battery cables or conectors could be bad If the battery is connected to your vehicle and it is not maintaining charge while the vehicle is running then it is more than likely your alternator that is out. If the battery does not have juice and is brand new then it is defective. I have also heard that if you place a car battery directly on concrete for a long period of time it will ruin. Always put a battery on a wood or a metal surface when storing.
With a charger specifically designed to charge this battery.
Any brand as long as it is the correct size battery.
I have learned that when i get new batteries for my hobby cars you want to fully charge the battery to the recommended hrs, you want to charge the battery fully because it will improve how long your battery will last on one charge and how long the battery's life will be.
How long does it take for an 18v battery to charge
