Short urban trips, extreme temperatures, and high accessory loads can shorten lifespan. In Greater Boston, seasonal swings and frequent stop‑and‑go driving make annual testing a smart practice. Land Rover Boston provides OEM-grade testing to verify state of health before your battery fails unexpectedly. If you’re unsure of battery age, check the case date code or stop by for a test.

• Plan a preventative test each year or before winter
• Replace proactively once the battery is 4+ years old
