For a 2018 Honda Civic, a replacement 12-volt battery typically costs between $120 and $300.
The price varies with the battery type (conventional lead-acid vs AGM), the brand and warranty, and whether installation is included or performed by a dealer, retailer, or independent shop. Prices can also vary by region and by retailer.
What affects the price
Several factors determine the final bill when you replace the 12-volt battery in this model. Here are the primary considerations.
- Battery type: Conventional lead-acid batteries are usually cheaper than AGM (Absorbent Glass Mat) batteries, which offer longer life and better performance in extreme temperatures.
- Brand and warranty: Well-known brands with longer warranties tend to cost more upfront but may save on replacements later.
- OEM vs aftermarket: Original Equipment Manufacturer (Honda) batteries are typically more expensive than aftermarket alternatives of equivalent specs.
- Group size and fit: The Civic uses a 12-volt battery sized to fit the engine bay; groups like 35 or 51R are common, and price can vary by size and compatibility.
- Installation and service: Some retailers include installation and disposal in the price; others charge separately, often $20–$120 depending on location and labor rates.
Prices reflect these variables, so shoppers should compare quotes and confirm whether installation is included when budgeting.

Where to buy
Consider these common channels when shopping for a 12-volt Civic battery. Availability and price can differ across channels, especially for installation services.
- Local auto parts stores (e.g., AutoZone, Advance Auto Parts, O'Reilly) often stock multiple brands and offer installation.
- Honda dealership parts or service departments can provide an OEM battery and dealer-driven installation, usually at the higher end of the price range.
- Online retailers and marketplaces (with shipping to you or to a local installer), which may offer competitive pricing but may require you to arrange installation separately.
- Independent auto repair shops and tire stores that provide battery replacement services, sometimes with lower labor costs than a dealership.
Before you buy, call ahead to confirm battery availability, group size, warranty terms, and whether installation is included or available on-site.
Summary
Replacing the 12-volt battery in a 2018 Honda Civic typically costs between $120 and $300, with conventional vs AGM, OEM vs aftermarket, and installation method driving the final price. Shop around across retailers, compare warranties, and confirm whether installation is included to get the best value. Keep in mind that regional prices and availability can shift these figures.
