    Hi guys.
    I have a car that has been sitting up for a few months . And when I went out to start it the battery had died. So I hooked it up to a battery charger . Its a 110ah battery . When I plugged it in first the amps were around 25 for a few secs and it then died down and settled at around 14-15amps . After 10 hours chargeing yesterday and another 5 today its down to 7 amps . But it doesnt seem to want to go any lower. How low should this go ? The battery was only bought from bmw new and put in the car in january .

    A feed of 25 amps is way too much and could result in damage. The best way to recover a flat battery, as previously suggested by Sitec, is to trickle charge it over a 24 hr. period.

    i didnt choose the amps it has a minimum and boost setting thats all.

    it was on minimum setting and when i initially plugged it in it went up over 20 for about 3 seconds and came back to 14 amps and is now down to 7
