IV. Usage and Maintenance Recommendations
Charging Management:
Float charge voltage recommended 13.5~13.8V (at 25°C), reduce by 3mV for every 1°C increase in temperature 57;
Avoid overcharging (voltage >14.4V) or undercharging (voltage <10.5V) 56.
Storage Requirements:
Unused batteries should be stored below 20°C, recharge every 6 months 57;
Mixing different models/brands of batteries is prohibited 13.
Fault Prevention:
Regularly check for terminal oxidation, clean and apply anti-corrosion coating 38;
Immediately stop use and inspect if localized overheating or abnormal gas evolution is detected 5.
