would a battery charger charge a flat battery?

my bats gone dead and wondered about this instead of buying me a new battery ?

worth a try....the e34 battery will be well over a hundred...(if its like mine)Make sure the water level(distilled is best) is over the plates and give it a try.You will be able to go day to day but if a cell has gone,a cold night a short lights on episode will drain it.

When this happened to my E39, I took it to the dealer for recharging and evaluation. They had the car for a day for recharging, and only cost $50. The best thing was the battery stooped being a problem anymore.

It might be the alternator that is the problem. When you jump start it again you should check the charge rate.. should be around 14 volts

Yea could be but i had a 525i last year and my alternator was gone and it had dime lights and low as power when i jump started it and it couldnt even go over 50 so im guessing it might not be this time it drives fine

how do i check the rate anyway? im going to try my mates battery in abit to see if its the battery or the alternator
