Source note: Honda’s European parts catalogue lists this car’s battery as part 31500-T50-E01, described as “46B24R(S)-MF” — maintenance-free, and not labelled AGM, unlike Honda parts for models that genuinely take one. The JIS B24 case is the same footprint UK suppliers number 057, and the (S) suffix means it carries standard DIN-size posts rather than thin JIS posts. Start-stop shows as not applicable because the e:HEV has no 12V starter motor — the hybrid generator cranks the engine from the high-voltage battery. We previously published this as a 45Ah AGM at 325 CCA; that CCA figure traced to a US Yuasa product listing rather than a UK fitment source, and the AGM attribute was unsupported.

Frequently Asked Questions
What battery does a Honda Civic need?
The Honda Civic (FL) 2.0 e:HEV takes a 46B24R(S) battery — the JIS B24 case, which UK suppliers sell as type 057 — rated 45Ah, with standard DIN-size terminal posts. Honda’s own part (31500-T50-E01) is a sealed maintenance-free flooded battery, not an AGM.
Does the Honda Civic need an AGM or EFB battery?
No. Honda specifies a sealed maintenance-free flooded battery for the e:HEV. An AGM in the same type 057 case will fit and is a reasonable upgrade, but it is not required: the e:HEV cranks its engine with the hybrid generator motor from the high-voltage battery, so no 12V starter motor draws on this battery.
How long does a Honda Civic battery last?
Typically 4–6 years depending on driving patterns. Short urban journeys and cold winters reduce battery life.
Can I replace the Honda Civic battery myself?
Yes for most models — it’s usually located in the engine bay. Disconnect the negative terminal first, then the positive. Fit the new battery in reverse order.
How we check fitment for this guide
We cross-reference fitment figures against manufacturer specifications and OE-supplier catalogue data where available, and matched to the standard codes that actually govern fit — battery type/group sizes, wiper lengths and fitting types, bulb fitment codes, tyre size markings, and oil specifications. We work by make, model, year, engine, and build date, because a single model can take different parts across its life. Where the right part depends on your exact vehicle, we tell you to confirm by registration or VIN. More on our method →
