INSTALLATION INSTRUCTION
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 originai lead-acid battery. Please check
the battery status before installation
Before installation:
• Please check the battery voltage with a multi meter. If the battery voltage is less than 13V, please
recharge it (Please refer to “Charging Instruction”).
• When connecting in series or in parallel, please ensure the capacity and voltage between each battery is
consistent (Please refer to “Instruction far Connecting in Series and Parallel”).
• Please check the battery and ensure the terminals are clean with no rust, the screws are clean without
foreign objects. Please ensure that the screws on the terminals are fixed/tightened to the maximum to
avoid loosening during operation.
• Please ensure that the length of the cable connecting the battery terminals is sufficient.
WARNING: PLEASE, ENSURE THAT THE MAXIMUM OUTPUT VOLTAGE OF THE CHARGING DEVICE
CONNECTED TO THE BATTERY DOES NOT EXCEED 14.6V BEFORE CONNECTING.
CHARGING INSTRUCTION
Please ensure charging voltage is 14.4V.
The charging current must not exceed the maximum charging current 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 will 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:
• Equalization mode
• Desulfation mode
• Pulse function
DO NOT leave the lead-acid battery charger connected to maintain or store the battery, because most will NOT
maintain the proper voltage charge algorithm for lithium batteries and damage will occur to the battery.
If you want to charge a battery with lead-acid charging system, make sure the charging voltage is less than 14.6V.
If charging batteries in series, make sure the charging voltage is less than 14.6V times the series number. For
e.g., if you want to charge batteries in 4 series, the charging voltage should be less than 58.4V, and the charging
current must follow the instruction in Charging Instruction.
