Critical Maintenance for Maximum Lifespan
Off-Season Charging Protocol: The leading cause of premature battery failure in recreational applications is sulfation during storage periods.
- Every 60-90 Days: Fully charge batteries using Razor-approved charger even when not in use
- Storage Temperature: Maintain below 85°F - higher temperatures accelerate self-discharge by 50% per 18°F increase
- Voltage Monitoring: Check resting voltage monthly during storage - readings below 12.4V per battery indicate immediate charging needed
- Post-Storage Procedure: After extended storage (3+ months), perform full charge cycle 24 hours before first use for optimal capacity recovery
Note: Sealed lead acid batteries naturally self-discharge at 3-5% monthly at room temperature. This is normal and does not indicate defect - quarterly charging prevents sulfation buildup that permanently reduces capacity.

We've Seen What Happens When Batteries Fail
- Sulfation from Storage Neglect: Batteries left uncharged for 3+ months develop permanent capacity loss - reducing ride time by 40-60% even when "fully charged"
- Incorrect Polarity Installation: Reversed connections damage speed controllers within seconds - requiring $60-80 controller replacement plus labor and downtime
- General-Purpose Battery Substitution: Non-HR rated batteries cause voltage sag under load - reducing performance and creating 30% shorter lifespan from deep-discharge stress
We choose our batteries accordingly. Because recreational equipment should deliver consistent fun.
HOW TO INSTALL RAZOR BATTERIES
- 1. Pre-Installation Safety Check: Ensure scooter is powered off and disconnected from charger - verify power switch shows no indicator lights before beginning battery access
- 2. Document Existing Wiring: Photograph battery orientation and wire connections before removal - polarity reversal is the leading cause of controller damage requiring $60-80 replacement
- 3. Connection Sequence: Connect batteries in series maintaining correct polarity - positive terminal of battery 1 connects to negative terminal of battery 2 for proper 24V system voltage
- 4. Voltage Verification: Test system voltage at main connector before reassembly - should read 24-26V indicating proper series connection and full charge state
- 5. Initial Test Ride: Perform 5-minute controlled test at half-throttle before full-speed operation - allows battery management system to stabilize under initial load conditions
