EV Battery Replacement Cost Calculator
Battery replacement is the big EV scare story. Get the real numbers — full pack vs module repair — and see if it ever makes financial sense.
2026 market: $100-200 + labor.
Full pack = all modules. A single failed module can be swapped for $1,500-4,000.

Costs fall ~5-8% per year as battery prices drop. Most owners will never need this — see the Battery Health Tracker to monitor yours.
Frequently asked questions
How much does it cost to replace an EV battery?
A full battery replacement costs $8,000-20,000 depending on the car and capacity — often 30-50% of the car's value. This is why most owners never replace one; they sell before it fails.
Is battery replacement covered by warranty?
Most manufacturers warranty the battery to 70% capacity for 8 years or 160,000 km. If your battery drops below that within the warranty, replacement is usually free.
Can I replace just one module instead of the whole pack?
Yes — many newer EVs allow module-level repair, costing $1,500-4,000 instead of a full pack. This is increasingly common as the industry moves toward repairability.
Should I budget for battery replacement?
For most owners, no. Batteries typically outlast the car. But if you plan to keep a car 10+ years or buy an older used EV, setting aside a small battery fund is wise.
