It isn't adviseable to use a battery charger to jump start a car unless the charger has a jump selection on it. Most newer models do have this function. The best thing to do, whether your charger has the jump function or not, is to take out the battery and put it on a trickle charge - usually about 2 amps, until the battery itself is fully charged.

What charger do you need for a 24 volt battery?
The formula you are looking for is I = W/E. Amps = Watts/Volts. 300/24 = 12.5 amps. A good charger with an output of 15 amps will do the job nicely. The time that it will take to charge the battery will depend on the amp/hrs of the connected battery and the state of discharge that the battery is in when charging starts.
