Maintenance & Cautions

• Ensure all batteries operating in a series based connection are not charged excessively;
• Ensure all batteries operating in a series based connection are not discharged excessively;
• Batteries must be charged with the correct voltage;
• Recharge capacity will be 1.1 - 1.15 times the discharge capacity;
• Effect of temperature on cycle charge voltage: -5mV/degrees per cell;
• It is imperative the battery is always in an upright position and never on its side.
