⚠️ What Size Battery Fits My Honda Civic? ⚠️

OPTIMA Batteries
Milwaukee, WI

The Honda Civic was first introduced to the public as a 1973 model in 1972. As of this writing, the Civic is now in its tenth generation and has proven to be one of the most-popular and best-selling cars in both the United States and Canada. With so many of these Hondas on the road and all the miles they accumulate over time, it's inevitable that their batteries will need to be replaced at some point.

So which battery fits your Honda Civic? In many cases, the answer isn't as simple as mentioning one size, because as the Civic has gone through ten different iterations, there are bound to be changes that have taken place, which may impact the battery that is best-suited and designed specifically to fit in your Honda. However, the Civic is one of those rare exceptions, that has remained relatively-constant in it's battery needs over the years, regardless of the generation of car or size of engine.

In many cases, the OPTIMA D51R is a direct-fit replacement for the Honda Civic. In fact, you can click here to buy a D51R factory-direct and have it delivered (for free) to your front door. Some manuals or battery guides may also list the 51R as a replacement battery, which is basically the same size as an OPTIMA D51R YELLOWTOP. The "D" in the OPTIMA battery name stands for deep-cycle, which means it can be used in both starting and deep-cycle applications, like car audio. The "R" in D51R means the post configuration is reversed from the normal orientation. That means as you look at the label on the top of the battery on a D51R, the positive terminal will be on the right-hand side and the negative terminal will be on the left-hand side.

OPTIMA also offers a D51 battery, which is identical to the D51R in every regard, except one very important detail- the terminals are reversed. That battery may come in handy, if the cables don't quite reach on a different application. It is important to make sure you get a battery for your Civic or any other vehicle you may own, that is a direct-fit replacement. While the D51R is a direct-fit replacement for most Honda Civics, that may not be the case for all of them, especially since the production spans more than 40 years.
