How many amps does a trickle charger need?

Can a dead battery be charged with a AAA Charger?
Probably too small of a charger to charge a dead battery in the vehicle given the parasitic loads and the relay. Probably the battery saver relay that was clicking? I would disconnect the battery from the car if I had to use a 2A charger. If you have AAA, get a jump. A 2 amp charger should easily out-charge any small key-off power draw.
What happens when you use a trickle charger?
Older trickle chargers simply pump-out the advertised amperage into the battery regardless of the battery state of charge. Even though the amps might not be a lot, say one or two, once the battery is fully charged those one or two amps will be overcharging the battery.
How long does it take for a dead battery to recharge?
Most trickle chargers require more than 24 hours to recharge a completely dead battery. Keep checking on the state of the battery by reading the trickle charger’s amp meter. Once the amp meter’s needle reaches 0, it means that the battery is fully charged.
What to do with a dead lead acid battery?
If it’s completely dead, it’s gone and you need to find a replacement. If you are lucky and there is enough juice left, you can hook it up to a smart battery charger and get more life out of the battery while desulfating the lead plates and bringing it back around.
What happens if your car battery is completely dead?

Can you jump charge a dead car battery?
Jump charging your dead battery could get your car running, but such a drastic method could shorten the useful life of your battery. The low yet steady charge provided by a trickle charger is a more reliable and exhaustive charge that results in extended battery life.
What does a negative battery charger reading mean?
A negative reading will indicate a bad battery charger, and you should replace it. If the charger has sufficient amount of power flowing through it, it’s more than likely the batteries are bad and just won’t hold a charge.
Can a trickle charger restore a dead battery?
To restore the battery, you will need a charger with a desulfation mode or a series of training charges with small currents. In this case, it is necessary to determine the characteristics of the battery that will help you choose the best trickle charger.
Can a dead battery charge a smart charger?
A fully dead battery will not have the voltage needed for modern smart chargers with internal safety sensors to detect and will not charge, but an artificial jump from a healthy battery for a few minutes may provide the voltage needed to engage the charger and bypass the internal safety sensor to charge your battery.
Where does the electricity from a charger go?
Without getting too complicated, a battery receives electricity from a charger. The electricity passes between the positive and negative terminals of the battery, by the plates, and through an electrolyte solution (the battery acid).
