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
Questions From Our Technical Support Calls
Q: "My Razor MX350 runs slower after battery replacement. Did I get bad batteries?"
A: Check polarity first - reversed connections reduce voltage to controller causing reduced speed without triggering failure. Verify 24-26V at main connector with multimeter. If voltage is correct, allow three full discharge/charge cycles for battery management system to calibrate - initial performance may seem reduced until system learns new battery characteristics.
Q: "How long should I expect batteries to last per charge?"
A: Depends on rider weight, terrain, and temperature. Under ideal conditions (120 lb rider, flat terrain, 70°F), expect 30-40 minutes continuous use. Real-world performance with 150 lb rider on varied terrain typically yields 20-30 minutes. Performance below 50°F decreases by approximately 20% due to chemical reaction rates in sealed lead acid chemistry.
Q: "Can I use a different charger or higher capacity batteries?"
A: Use only Razor-approved 24V chargers designed for sealed lead acid chemistry. Generic chargers may overcharge causing premature failure or undercharge leading to sulfation. Higher capacity batteries (9Ah, 12Ah) will physically fit but exceed controller current ratings - potentially causing overheating and shortened controller lifespan. Stick with OEM specifications for reliable operation.
Q: "Why choose High-Tech Battery Solutions over generic suppliers?"
A: After 15 years specializing in electric scooter batteries, we understand the failure patterns specific to recreational applications. Generic suppliers often ship batteries that have been warehoused for 6+ months at unknown temperatures, reducing effective lifespan by 20-30%. Our batteries ship fully charged within days of quality testing using Midtronics equipment. Plus, we provide technical support based on thousands of actual installations, not just specification sheets.
