how many hours will it take to charge my car battery?

Charging time can vary depending on how long dead the car battery is.The longer the battery is left the battery cells become weaker therefore needing more time to charge up.Sometimes it can take ages for the battery to get a good strong charge that is strong enough to start up your car.Some quality chargers that are rated at a higher amp will charge much quicker if compared to cheap chargers that is rated at a  lower amp.Charging you battery does not always guarantee a full charged battery so you might be forced to buy a new battery instead.
