How do you remove the battery on a 2003 Honda Shadow 750?

Remove the two bolts that hold the rear of the seat, then lift seat up and pull back. Remove the plastic cover above the battery. Now you can remove the battery terminal cables, start with the negative and end with the positive cable. Lift the battery up and out of its housing or box. If it is stuck there then check if there is foam or weather stripping holding it in place. If this is the case, a sudden jerk upward will free the battery. Put the new battery in, make sure it turns the same way as the old battery did. Now connect the battery cables, beginning with the positive and ending with the negative terminal. Put the cover above the battery in its place. Finally, fasten the seat in the reverse order that you removed it.
