What type of battery does a 2015 Honda Fit take?

A 2015 Honda Fit in North America typically uses a 12‑volt BCI Group 151R lead‑acid starting battery (with “R” denoting reverse terminal layout, i.e., the positive post on the right when the posts face you). Most owners choose a standard flooded battery in this size; an AGM battery in Group 151R is an acceptable upgrade if available. In some non‑U.S. markets—especially models with idle stop/start (sometimes sold as Jazz)—Honda specifies an EFB or AGM battery in a JIS size such as 46B24R or 55B24R, so verifying the label under your hood or the owner’s manual is recommended.

The standard fitment for U.S. and Canada

For gasoline, non‑hybrid 2015 Honda Fit models sold in the U.S. and Canada, the factory fitment is a compact, reverse‑terminal battery designed for small-engine cranking and tight engine bays. This size is widely available at auto parts retailers and dealerships.

Below are the key specifications most owners should look for when buying a replacement battery for a 2015 Honda Fit in North America.

• Group size: BCI 151R (12 V SLI starting battery)
• Polarity: Reverse (positive post on the right when posts are nearest)
• Dimensions (approx.): 9.3–9.4 in L × 5.0–5.1 in W × 8.6–8.8 in H (237–240 × 127–130 × 218–224 mm)
• Cold Cranking Amps (CCA): commonly 320–410 CCA; choose equal or higher than the original rating for your climate
• Reserve Capacity (RC): typically about 60–75 minutes (varies by brand)
• Chemistry: Flooded lead‑acid (OEM); AGM is an optional upgrade if available in 151R

Meeting or exceeding the original CCA and matching the 151R group ensures proper fitment in the stock tray and sufficient starting performance.

Variations by market, trim, and equipment

Battery specifications can vary outside North America and on models equipped with fuel‑saving features. If your Fit/Jazz has idle stop/start or is a hybrid variant in certain markets, Honda typically requires an enhanced battery due to frequent cycling.

These are the most common deviations from the North American spec you may encounter.

• Idle stop/start (non‑U.S. markets): Often uses EFB or AGM batteries in JIS sizes such as 46B24R or 55B24R to withstand increased charge/discharge cycles
• Hybrid/HEV variants (region‑specific): Usually require an AGM 12 V auxiliary battery sized to the JIS specification used in that market
• Dealer updates: Some regions may supersede earlier flooded batteries with AGM/EFB under service bulletins for durability

When in doubt, check the under‑hood battery label, your owner’s manual, or a reputable fitment guide for your market and trim.

Compatible replacement options and what to look for

Most major battery brands sell a direct‑fit Group 151R for the 2015 Honda Fit. Focus on fitment, warranty, and performance appropriate for your climate and driving pattern.

Use this checklist to select a suitable replacement.

• Confirm group size 151R and reverse polarity so it fits the tray and cables without modification
• Match or exceed the OEM CCA; higher CCA can help in cold climates
• Consider AGM if your driving is mostly short trips or if you want better vibration resistance and lower self‑discharge
• Check warranty length (free replacement period) and nationwide support if you travel
• Verify height clearance under the hood; stick to the 151R footprint and height range

Following these points will help you balance cost, longevity, and reliability while ensuring a straightforward installation.

Installation notes and memory settings

Swapping the battery on a 2015 Fit is typically straightforward and does not require dealer “battery registration.” However, preserving vehicle memory settings can save time.

Keep the following tips in mind during installation.

• Use a memory saver (OBD‑II or 12 V accessory saver) if you want to retain radio presets and clock
• Disconnect negative (−) first and reconnect it last to reduce the risk of short circuits
• Clean terminals and ensure tight, corrosion‑free connections; secure the hold‑down so the battery cannot move
• After installation, start the car and let it idle for a few minutes to allow the ECU to relearn idle parameters
• Recycle the old battery at the retailer; you may receive a core credit

Proper installation helps maximize battery life and avoids intermittent electrical issues.

How to confirm your exact battery spec

If you’re unsure which battery your 2015 Fit needs—especially if you’re outside North America or your car has idle stop/start—verification takes only a few minutes.

Use the steps below to confirm the correct battery before purchase.

• Check the label on your current battery for group size and CCA
• Consult the owner’s manual under “Specifications” or “Battery”
• Use fitment tools from major retailers by entering year/make/model/engine
• Contact a Honda dealer with your VIN for market‑specific guidance

Confirming these details ensures you buy a battery that fits physically and meets Honda’s electrical requirements.

Summary

For a 2015 Honda Fit in the U.S. and Canada, the correct replacement is a 12‑volt BCI Group 151R starting battery with reverse terminals; most drivers use a standard flooded type, while AGM is a viable upgrade. Models with idle stop/start or those sold in some other markets may require an EFB or AGM battery in a JIS size such as 46B24R/55B24R—so always verify your specific vehicle’s label or manual before purchasing.
