* Charging voltage is 14.4V
* Ambient humidity: ≤85%
Cautions: Improper use will cause irreversible damage to the battery, and could cause
battery swelling and smoke in extreme cases.
Please follow the vehicle/equipment manufacturer's instructions:
• When replacing various types of deep cycle applications, please ensure the battery capacity is not
less than the original lead-acid battery.
• Please check the battery status before installation:
* Please check the battery voltage with a multimeter. If the battery voltage is less than 13V, please
recharge it (Refer to "Charging Instruction").
* When connecting in series or in parallel, please ensure the capacity and voltage between each
battery is consistent (Refer to "Instruction for Connecting in Series and Parallel").
* Please check the battery to ensure the terminals are clean with no rust, and the screws are clean
without foreign objects.
* Please ensure that the cable connecting the battery terminals is long enough.
* Please ensure that the screws on the terminals are fixed/tightened to the maximum to avoid
loosening during operation.
* Please ensure that the maximum output voltage of the charging device connected to the battery
does not exceed 14.6V before connecting.
Installation Instruction
• Please ensure charging voltage is 14.4V.
• The charging current must not exceed the maximum charging current which is indicated in the
specification sheet in this User Manual.
• The batteries used in series do not need to be disassembled for separate charging, but ensure that
the individual batteries must be fully charged before connecting in series. For details, please see
"Series and Parallel Precautions".
• Please ensure to charge at an ambient temperature of 0°C~45°C. Below 0°C or above 45°C cause
irreversible damage to the battery or even a safety risk.
• You must NOT use a lead-acid battery charger if it has any following mode or function:
