⚡ VoltSens Verified Automotive Research & Analysis
Every EV manufacturer advertises attractive warranties like '8 Years / 1,60,000 km'. But what happens when your battery only delivers 60% of its original range after 4 years? Does the company replace it for free?
Understanding the 70% State of Health (SoH) Threshold
Most reputable brands guarantee that if the battery capacity degrades below 70% (or 75%) within the warranty period, they will repair or replace modules free of cost. Normal degradation down to 80% is considered standard chemical aging and is not covered.
Actions That Void Your EV Battery Warranty
- Using unapproved third-party fast chargers or modified extension cords.
- Submerging the battery beyond the IP67 time limit (waterlogged flood parking).
- Tampering with or opening the sealed battery enclosure.
- Leaving the vehicle completely discharged (0% battery) for more than 30 consecutive days.
