If you're unsure which version you have, simply send us photos and we’ll help identify it.
🔋 Upgrade Options
Don’t just restore—upgrade.
Super73 batteries (serviceable models) are excellent candidates for upgrades using premium cells such as Samsung, LG, or Molicel.
Upgrade benefits:
- Increased range per charge
- Improved power delivery and acceleration
- Reduced voltage sag under load
- Extended lifespan (typically 3–5 years with proper care)
🧪 Diagnostics & Testing
Every serviceable battery goes through a comprehensive in-house process:
- Initial inspection and diagnostics
- Precision rebuild with matched cells
- BMS functionality evaluation
- Full charge/discharge testing before shipment
⚠️ Important Notes on Super73 Batteries
Super73 batteries vary significantly by generation.
- Older models are generally fully serviceable and upgradeable
- Newer models (especially RX gas tank style) may have limited or no rebuild capability due to proprietary BMS systems
- We always verify compatibility before proceeding
