1A Trickle Charge Import Car Battery How Long

Posted in Car Batteries | Asked on Apr 23, 2010

I’ve got a dead import car battery sitting in my car. I haven’t been using my car for about three months and about a week ago, I noticed that the anti-theft light on the radio wasn’t blinking any more.

I have a 1A battery trickle charger, more meant for motorcycle batteries.

I’ve got a 24hr lamp switch timer where I can connect the trickle charger and have rigged it up to charge the battery in 15 minute spurts.

Time is not an issue in charging the battery. I’ll probably use the car again in about a month when the weather gets really bad.

My question is how long would it usually take to charge a battery if I were to continously charge it from 0 to 100% and how many total hours a day would you recommend to charge the battery to slowly bring it back up to 100% in about a month? Remember, I’ll be charging it in 15 minute spurts to be easy on the battery and give it a chance to ‘rest’ between 15 minute charges.

Thanks

    You dont have to give it a rest between charges With a trickle charger about 24 hours would be good. Remember if you dont get it all the way charged when your car is running it will charge it fully. what you want to prevent is charging it fully and then allowing the charge to go to zero. when a battery is taken completely thru the charging spectrum it has a tendency to warp the lead plates in the battery This causes a short and will kill your battery.

    Put the charger on and leave it on till you drive the car again. 1 amp will take a long time and the charger has a limiter so it won’t overcharge.

    Lose the idea that the battery will come back to 100%, because this doesn’t happen. For the tiny light on the anti-theft device to go off, the battery is simply too far flat for a charger to do any good. The timer thing is way out in left field. The 1 amp motorcycle charger could have helped two months or so ago but, the trick to keeping a battery up, while in storage, is to use a float charger. Float chargers are inexpensive low current units that only charge when the battery needs charging.
    Now to your battery problem, the solution is to buy a new battery and install it along with a float charger.
