2026 RAM 1500-Rev Battery in Denver, CO

Expect about 3–5 years for the 12‑volt battery on a 2026 Ram 1500 REV under normal use.

Auxiliary 12‑volt batteries in EVs handle starting electronics, safety systems, and accessories. Short trips, extreme temperatures, or long parked periods can shorten life. Our Denver service department can test state of health in minutes and advise on replacement timing to prevent no‑start situations.

• 12‑volt batteries typically last 3–5 years
• Frequent short drives and heat/cold reduce lifespan
