The equation that you are looking for is W = I x E, W = amps x volts. As you can see you need the value of volts to use in the equation to obtain your answer.

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.
