⚡ Charging Specifications

Correct charging is essential for maximising Crystal Gel battery performance and service life.

Recommended charging parameters include:

• Cycle Charge Voltage: 14.4–14.8V at 25°C
• Maximum Charge Current: 10.5A
• Float Charge Voltage: 13.6–13.8V at 25°C

Always ensure your AC charger, DC-DC charger or solar regulator is configured appropriately for Gel / Crystal Gel batteries.

🔄 Low Self-Discharge

The Razorback 35Ah Crystal Gel Battery has a low self-discharge rate of approximately 3% per month at 25°C.

This makes it particularly useful for applications that may sit unused for periods between operation, including:

• Caravans
• Boats
• Camper trailers
