Parts for your 2010 Honda Elysion-Batteries

2010 Honda Elysion Batteries

Based on technical references including the Honda Elysion Owner’s Manual (2010, JDM), Honda Service Information for RB/RC-series Elysion models, and supplier fitment data from GS Yuasa/Panasonic application guides, the 2010 Honda Elysion uses a conventional 12‑volt lead‑acid starter battery. There’s no high‑voltage hybrid system on the 2010 Elysion, so the single 12V battery handles engine cranking, ECU and safety systems, lighting, accessories, and stop/start of petrol engines like the K24A 2.4L and J30A 3.0L V6.

The battery’s job is simple but critical: deliver a strong burst of current to crank the engine, then keep electronics stable when loads spike. On this model, common fitments are JIS B24L sizes (often labelled 46B24L, 55B24L or NS60LS in AU/NZ), with left‑hand positive terminals. Capacity and CCA vary by trim and climate, but many owners see best results around 45–60 Ah and 430–550 CCA. Always match terminal layout and hold‑down style to avoid cable strain or loose fitment.

• Typical lifespan is 3–5 years. Test at every service, earlier replacement is wise if cranking slows or voltage sags.
• Healthy readings: 12.6V+ at rest, and roughly 13.8–14.8V charging with the engine running.
• Keep terminals clean and tight, a light smear of dielectric grease helps curb corrosion.
• If the vehicle does frequent short trips, give the battery a maintenance charge now and then to prevent sulphation.

When it’s time to replace the battery, a few sensible steps keep things drama‑free:

1. Preserve memory if possible (radio code, clock, idle learn) with a memory saver. Many Hondas of this era will ask for a radio security code after loss of power.
2. Ignition off. Remove the negative (–) terminal first, then the positive (+), and the hold‑down. Lift the battery straight up.
3. Seat the new battery firmly, refit the clamp, connect positive first, then negative. Don’t over‑tighten posts.
4. Start the engine and let it idle. If idle is unstable, perform a basic idle relearn and reset auto‑up windows if needed.

No battery registration is required on the 2010 Elysion, and there’s typically no smart sensor on the negative lead. If a new battery still goes flat, have the charging system and parasitic draw checked. Recycle the old unit responsibly—most parts stores will take it.

What battery size suits a 2010 Honda Elysion?
Most trims take a JIS B24L footprint, commonly listed as 46B24L, 55B24L or NS60LS in AU/NZ. Match terminal layout (left‑hand positive), hold‑down, and aim for 45–60 Ah and 430–550 CCA. Always confirm against the existing battery label or the vehicle’s service info.

How long should the battery last?
Typically 3–5 years. Hot weather, short-trip driving, and heavy accessory use can shorten life. Regular checks, clean terminals, and keeping it fully charged will help it go the distance.

Will the Elysion need coding after a battery change?
No ECU “coding” is required on the 2010 Elysion. However, the radio may need its security code, the clock will reset, and the idle or auto‑up windows may need a simple relearn. Using a memory saver can avoid most of that hassle.
