Stromer Battery | Rebuild Service

Is your Stromer battery losing range, failing to charge fully, or no longer delivering reliable performance? Don’t replace the whole pack — revive it with our Stromer Battery Rebuild Service. We retain your original battery housing, connectors, and mounting interface, while replacing all internal cells with fresh, high-quality lithium-ion modules—restoring performance and extending life at a fraction of replacement cost.

Rebuild Options

Standard Rebuild – Restores your battery to its original factory-rated capacity using premium cells.
Upgraded Capacity – When your housing, wiring, and BMS support it, we can increase the amp-hour (Ah) rating for additional range (subject to compatibility).

What’s Included

Replacement of all internal lithium-ion cells
Inspection, cleaning, and refurbishment of your existing battery housing, wiring, and contact points
Performance testing, cell balancing, and verification
Reuse of your original BMS (Battery Management System), or replacement if necessary (additional cost may apply)
90-day workmanship warranty on the rebuild
