Positive First. When installing a mower battery, always connect the positive cable first. The positive cable is red. It attaches to the battery terminal post marked with a plus sign, the letter P or the word POS. Attach the negative cable last. The negative cable is black.

This is appropriate for a mower battery to prevent damage or explosion.tep 2. Disconnect the positive and negative cables from the battery. The mower battery will either have a cable end, like a car, or most will have a bolt that goes through the cable end and terminal to hold the cable on.
