The Short Answer: Connect the Positive Terminal First
Which terminal Positive or Negative should be connected First When Installing a new Battery on the Car? Which terminal - positive or negative - should be connected first? In this article, we will discuss the answer to this question and the reasons behind it. However, when it comes to replacing or installing a new car battery, there is a common question that arises: They provide power to start the engine and supply electricity to other systems such as lights, radio, and air conditioning. However, many people are not sure which terminal to connect to first – positive or negative.Ĭar batteries are essential components of a vehicle's electrical system. We also keep an eye on our Twitter account on the weekends.When installing a new car battery or replacing an old one, it is important to connect the terminals correctly.

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. OPTIMA battery chargers and maintainers were specifically designed to be very user-friendly and are some of the easiest to use in the entire industry.
We make a practice of topping off the charge on our car batteries once a month, even if we use them every day, because the electrical demands of modern vehicles and/or the driving habits of their owners may make it very difficult or impossible for the vehicle's charging system to keep the battery fully-charged. If that sounds too complicated for your level of mechanical ability, it's safe and conservative to assume your car battery is not fully-charged, because the fact of the matter is, most car batteries are not fully-charged.
