2022 Mitsubishi Eclipse Cross Batteries — What They Do and How to Look After Them

Yes, batteries are absolutely relevant and used on the 2022 Mitsubishi Eclipse Cross. Mitsubishi’s 2022 Eclipse Cross Owner’s Manual outlines the 12‑volt battery as the core power source for cranking the engine and running vehicle electronics, and the Eclipse Cross PHEV publications further describe a high‑voltage lithium‑ion traction battery for electric drive alongside a conventional 12‑volt auxiliary battery. These details are documented in Mitsubishi Motors owner’s and service literature for the 2022 model year, and in official PHEV specifications noting a lithium‑ion drive battery of around 13.8 kWh.

On any 2022 Eclipse Cross, the 12‑volt battery keeps the essentials ticking along — from the starter motor and engine control units to lighting, security, stop/start (if fitted), and infotainment. In the PHEV variant, a high‑voltage traction battery drives the electric motors, but a regular 12‑volt battery still handles computers, relays, locks, and safety systems. If the small battery is weak, modern features can play up long before the car refuses to start, so it pays to keep it in good nick.

For servicing, it’s smart to test the 12‑volt battery annually (or before big trips). Look for clean, tight terminals, no corrosion, and a secure hold‑down. If the vehicle has idle stop/start, use the correct EFB or AGM replacement as specified by Mitsubishi — swapping to a cheaper “standard” unit can shorten battery life and upset stop/start performance. When replacing, maintain vehicle memory with a support tool if possible
