The first priority is to choose the correct size battery. Manufacturers use a Group system to classify batteries by size. The Honda Civic battery is in Group 51.

Another vital feature to look out for is the battery’s starting power, known as the Cold Cranking Amps (CCA). This is a measure of the power the battery has to start an engine from cold.

Feature #1: Size- Group 51 or Group 51R

What Group Size Battery does a Honda Civic use?

The best way to check the size of the battery you need is to look in the owner’s manual. Batteries are not made for specific cars. Instead, car manufacturers design the battery space to accept a standard battery size. In the case of the Honda Civic, you should use a Group 51 battery type.

There are two types of battery in this group, the 51 and the 51R. The only difference between the two types is the location of the battery terminals. Make sure you choose the correct type because if you fit the wrong type, the battery cables may not reach, or you may find the cables are stretched too much.

If you are searching online for a new battery, many websites, such as Amazon, allow you to search by vehicle make and model. This way, you will only be shown the correct batteries for your car.

Battery Recommendations based on Group Size

Below are the Honda Civic Battery recommendations based on Group Size. But don’t worry, we always consider the CCA rate when choosing these batteries to make sure that they can easily start your engines.

Group 51 Batteries for Honda Civic

Optima D51 Battery: Spend more – Save more

Optima D51 Honda Civic battery
Optima Group 51 450 CCA Battery
This dual-purpose battery fits perfectly in most Civic models. It meets the CCA requirement to start Civic cars, and has RC of 55 mins for constant performance.

Price range: $260-$270.

The Optima D51 is a Group 51 battery, measuring 9.21 x 4.98 x 8.94 inches (L*W*H). This makes it ideal for Honda Civic models that use the Group 51 size batteries.

The Optima is one of the companies Yellow Top range, built to withstand vibration and increasing battery life. Fitting the correct size battery also helps to reduce vibration, as the battery holder strap will secure the battery tightly in place.

Other features of this battery include a deep-cycle capability and 450 cold-cranking amps, making this a powerful unit. The deep-cycle feature allows the battery to drain to a very low voltage regularly without being damaged.

Group 51R Batteries for Honda Civic

Optima Yellow Top Group 51R: Big brand, Is investing really worth it?

Optima Group 51R Honda Civic Battery
Optima D51R 450 CCA Battery
The same specs of Optima D51 but the positive terminal is on the right, which is perfect for standard Honda Civics.

Price range: $259-$269.

The OPT8073-167 is the Group 51R equivalent of the Optima 8071-167 D51 battery mentioned earlier. The specification of size and weight of both batteries is identical. The only difference is in the position of the battery terminals.

If you look at the battery labels on the Group 51 version, the positive terminal is on the left. On the Group 51R battery, the positive terminal is on the right. On a standard Honda Civic, the Group 51R is the standard fitment.

Megavolt BCI 51R: Lower-priced than ever

Megavolt 51R
Megavolt Group 51R 550 CCA Battery
This is the cheapest battery that you could find for your Honda Civic. It is known to withstand even the challenging weather conditions with 550 CCA.

Price range: $115- $125.

The Megavolt is a Group 51R battery measuring 9.29 x 5 x 8.78 inches (L*W*H), making it slightly larger than the Optima 8071-167. But as it’s a Group 51R battery, it’s still the correct size for some Honda Civic vehicles.

Compared to the equivalent Optima batteries mentioned in this review, the Megavolt is heavier. The increased weight is due to the Megavolt being an acid-flooded battery, where the Optima’s use the newer absorbed glass mat (AGM) technology.

The more recent AGM specification saves around three pounds in dead weight, something that’s important to performance enthusiasts.

Feature #2: CCA

How many CCAs does your car battery have?

Every battery type is different, and the Cold Cranking Amps (CCA) will usually be stamped on the side or top of your battery. The standard battery fitted to the Honda Civic was a 410 CCA. However, group 51R batteries generally have more than 500 CCA, making them more powerful than the OEM battery.

If you live in colder climates, this makes the engine more difficult to turn over and start. Oil gets more viscous as the temperature drops, so choosing a battery with a higher CCA in these climates is a good option.

Battery Recommendation based on CCA

The standard battery had a CCA of 450 amps for older Honda civic models, but later models had over 500CCA. The extra power helps turn the engine over in colder conditions and is generally recommended in place of lower CCA batteries.

XS Power D5100R XS: Perfect Choice For The Most Challenging Weather Conditions

XS Power D5100R
XS Power Group 51R Battery
This XS Power battery is pricey but worry-free. With 745 CCA, it can start your Honda Civic like a champ even after a long time of no use.

Price range: $285- $295.

The XS Power D5100R XS provides a whopping 745 CCA in a Group 51R battery size, making it perfect for the Honda Civic with the dimensions of 9.04 x 5.43 x 8.19 inches. With an extra 295 CCA compared to the standard model, it will have no problem starting the Civic.

The XS Power is an AGM-style battery that benefits from its advantages in low maintenance and no chance of acid spillage. It should be mentioned that this battery is slightly larger than the Group 51R standard, so measure carefully before ordering one for your Honda Civic.

Tips When Buying A Honda Civic Battery

Getting the correct battery for your Honda Civic is essential for long working life and preventing the battery from letting you down.

  • Check the size requirement for your battery. Most Honda Civic models use the Group 51R battery, but there are differences between model years. Check the owner’s manual or ask your dealer.
  • If you want more power, you could fit a larger battery, but this may mean that the battery won’t fit the standard tray. Larger trays are available if you have space.
  • Check the battery manufacturing date code. It would be best if you looked for a battery less than two months old. The code is in a four-digit form. For example, the code 12/08 means December 2008.

1. Should I choose an AGM battery or SLA battery?

AGM and SLA batteries both have their advantages and drawbacks, so choosing AGM or SLA battery depends on your expectations and your budget.

Below are the pros and cons of each type:

Pros and cons of SLA Batteries:


  • Lower price
  • SLong working life
  • Available for almost every vehicle type


  • Must be securely mounted in a vertical position to prevent leakage
  • Regular maintenance is required to prolong their life
  • The release explosive and toxic hydrogen gas during charging
  • Susceptible to damage by movement and vibration

Pros and cons of AGM Batteries:


  • No danger of acid leakage, can be mounted in any position
  • Low maintenance
  • Very little gas is released during charging
  • Resistant to damage through vibration and movement


  • More expensive compared to SLA/FLA batteries
  • Incorrect charging may damage the battery

2. How long does a Honda Civic battery last?

The working life of a lead-acid battery is dependant on many factors, but you should typically expect between three and six years. Some factors affecting life include;

  • Regular maintenance. FLA batteries require acid topping up, which SLA and AGM batteries do not. However, all types of batteries will benefit from being connected to a reconditioning trickle charger at regular intervals
  • Working conditions. Vibration is a killer for some batteries, particularly the FLA and SLA types. Mounting your battery correctly and adding some vibration absorbing material can help to extend the battery’s life.

3. What is the Ah rating and is it important?

The Ah rating of a battery is a measure of the power a battery can provide and for how long. For example, a 100Ah battery can provide 20 amps for five hours. Alternatively, it can provide 5 amps for 20 hours.

It is important to make sure that when you buy a replacement battery that it has an Ah equal to or greater than the manufacturer’s standard battery.
