Install Car Battery Positive Or Negative First. Never connect the negative cable to the battery itself. Only a small part of the car is now connected to power.
Ensure that all cable connections hold downs are properly tightened. First most alkaline batteries have and - signs to indicate the positive and negative sides. Place your new battery in the battery tray make sure your battery is fully charged.
If you can just connect the positive red alligator clamp to the positive terminal and the negative black alligator clamp from the charger to a metal ground on the car or the negative battery post and plug the OPTIMA charger in to an outlet it will eventually turn on automatically and do the rest.
The positive terminal in most cases has a red cover and is connected to the post on the battery that is stamped by a plus sign. Never connect the negative cable to the battery itself. Spray both terminal ends with anti-corrosion solution. Connect the positive post of the first battery to the positive post of the second battery.
