Charging time for a car battery?

i have an electric scooter with a car battery running it. i charge the scooter with my 2/10 amp (selectable) car battery charger. if the battery is fully charged, is it bad to leave the charger going? say if i leave the house for a couple of days and just want to keep it at a nice top charge for when i get back.

Should be OK on the 2 AMP setting.

it should still be okk.

Just don`t leave it sitting on the cement as it will kill your battery once you stop charging it.

it should be fine on 2 amp setting ( trickle charge)

if it is a 'full charge' type, it will blow up....but if it has a 'trickle charge mode', it will be fine....

It will be ok just keep an eye on it and get a new battery ASAP.

any car battery is good for 4/5 years , after that time the battery is spent, now about your charger, when your battery is low , it's the best practice to slowly charge at 2amps, all night, the needle on the charger will come down to 0 by morning , the high charge all night will boil the battery , never leave it plug ed in longer then overnight , the life of the battery will be extended charging low and steady.
