Commercial electric delivery vans and two-wheelers carry 3 to 8-year battery warranties tied to both calendar age and battery state-of-health. Missing the degradation claim threshold voids costly pack replacements.

Commercial fleet electrification is accelerating rapidly across urban last-mile delivery and transit networks. Unlike conventional internal combustion engine (ICE) vehicles where maintenance focuses on fluids and filters, the single most valuable capital asset in an electric vehicle is the traction battery pack, often representing 40% to 50% of the vehicle's total replacement cost.
OEM commercial battery warranties feature strict dual covenants: a fixed calendar duration (e.g., 5 years or 150,000 km) and a minimum retention of State-of-Health (SoH), typically 70% to 75%. If degradation drops below that line within the time limit, the OEM owes you a free pack repair or replacement.
Battery warranties contain stringent exclusion clauses. High-temperature fast charging beyond recommended cycles, operating with firmware updates ignored, or neglecting scheduled coolant flush intervals are grounds for warranty denial.
Fleet operators must maintain an indisputable record of every scheduled preventive maintenance visit and BMS diagnostic log to defend high-value battery replacement claims.
Because battery degradation is cumulative, commercial packs frequently hover around 68% to 72% capacity near the end of their fourth or fifth year. Without proactive monitoring, the warranty expires silently while the battery is already below the guaranteed threshold, leaving the enterprise with a ₹3,00,000+ pack replacement liability.
By logging vehicle delivery dates, OEM warranty end dates, and service schedule milestones into RenewOS, fleet managers receive actionable alerts 90, 30, and 7 days prior to warranty expiration, ensuring health evaluations happen while claims are still 100% enforceable.
