Inspection
Please check for visible damage including cracks, dents, deformation, and other visible abnormalities. The top of the battery and terminal connections should be clean, free of dirt and corrosion, and dry. If any problems are detected with the battery, please contact us for assistance. Refer to the last page of the manual for contact information.
Before installation, use a voltmeter to check the voltage status of the Na+ battery. If the voltage is lower than 12.8V, please charge it before installation.
Battery Installation

Step1. Check The Vehicle’s Circuit System
Please follow the vehicle manufacturer’s instructions for installation, and use a dedicated charging voltage detector to check the vehicle circuit system.
Step 2. Dismantling Old Battery
Remove the original battery from the vehicle according to the manufacturer’s instructions. Be sure to remove the negative bolt and wire ﬁrst, then the positive bolt and wire to avoid short circuits.
Step 3. Check If Na+ Battery Is Compatible With The Vehicle
➀ Size, cold cranking amps, terminal location and battery type are key factors in getting the right device. Please measure your old battery and compare size with this battery, If the measurements are the same, the positive and negative poles are consistent, there is not much diﬀerence in CCA, it will ﬁt your vehicle.
➁ Check the battery polarity, the Na+ battery must be the same as the original one.
➂ Check whether the size, length, width and height of the Na+ battery are consistent with the original battery. This is to avoid the situation where the Na+ battery is too large to be properly installed in the vehicle.
Note

Typically, Na+ battery are the same size as the original battery, or smaller. The same size or Na+battery is smaller in size than the original battery and can be directly installed in the vehicle.
If you need to change the battery size, you can stick foam strips on the bottom and sides of the Na+ battery to make it closer to the original battery size. IMAGE ➀

Step 4. Connect Na+ Battery Torque
Select the cable and locking screw of the appropriate size and use them to tighten the connection torque of the battery.

Step 5. Connect Na+ Battery To The Vehicle
Securely connect the positive and negative wires from the motorcycle or vehicle to the battery terminals. The red wire is connected to the positive pole, and the black wire is connected to the negative pole It is strictly prohibited to start the ignition with the positive and negative poles reversed. IMAGE ➁

Step 6. Check Battery Voltage After Connecting
Connect the charging voltage detector ﬁrmly to the two wires of the vehicle or motorcycle, paying attention to the correct connection of the positive and negative poles. At this time, the detector will display the terminal voltage of the battery.
Step 7. Motorcycle Charging System voltage Detection
Disconnect the negative terminal of the battery from the negative terminal of the motorcycle. The detector will display the charging voltage of the motorcycle charging system.
Control the motorcycle speed at 2000-5000rpm and read the voltage of the detector respectively:

When the voltage is 14.0V-16.0V, the charging voltage is normal.
When the voltage is lower than 14.0V, the battery is undercharged
When the voltage is higher than 16.0V, the battery is overcharged.

When the battery is undercharged or overcharged, it will cause abnormality and damage to the battery, and the motorcycle charging system needs to be maintained.
Step 8. Connect A Multimeter To Detect Parking Current
Turn oﬀ the motorcycle switch, connect a multimeter that can measure milliampere current in series between the negative pole of the battery and the negative pole of the motorcycle, and use the milliampere current range to measure the static power consumption of the motorcycle to ensure that the parking current of the motorcycle is less than 1mA.

BATTERY CHARGING

When using a vehicle or external charger to charge the battery, the charging voltage should be limited to 14V-16V.
When using an external charger to charge the battery, please remove the battery from the vehicle and do not charge it in the vehicle.
After external charging, please leave the battery for one to two hours and check its voltage. If the voltage is less than 12.8V, continue charging.

BATTERY TRANSPORTATION

When transporting the battery, please ensure that the battery power is around 50%.
During transportation, please use insulating and shockproof materials to pack the battery to avoid collision and extrusion during transportation, which may cause damage to the battery.
Please handle with care during transportation and loading to avoid dropping or bumping the battery.
Do not transport together with ﬂammable, explosive or sharp metal objects.

BATTERY STORAGE

When storing the battery, keep the battery charge above 70%.
The battery should be stored in a ventilated and dry environment to avoid contact with corrosive substances.
Keep away from high temperature and open ﬂame environment.
During storage, it is recommended to charge the battery every 180 days and fully charge the battery.

BATTERY MAINTENANCE
When the vehicle is not used for a long time, the battery should be removed or disconnected to prevent leakage or over-discharge of the battery, which may cause damage to the battery.

The vehicle and battery should be checked regularly to keep the positive and negative poles of the battery clean and ﬁrmly connected.
If the battery voltage is found to be lower than 12.8V during storage, the battery should be charged in time
Do not use a maintenance charger for long-term maintenance of the battery.

WARNING

DO NOT immerse the battery in water or allow it to get wet.
DO NOT use or store the battery near sources of heat such as a ﬁre or heater.
DO NOT reverse the positive (+) and negative (-) terminals.
DO NOT connect the battery directly to wall outlets or car cigarette-lighter sockets without proper charging equipment.
DO NOT allow exposed ends of cables connected to opposite terminals to touch.
DO NOT put the battery into a ﬁre or apply direct heat.
DO NOT use the battery if the battery casing has been pierced, broken, cracked, or otherwise visibly damaged.
DO NOT throw the battery or heavily strike the battery in any way.
Never solder anything directly to the battery terminals.
DO NOT attempt to open or modify the battery in any way.
DO NOT mix batteries of diﬀerent capacities, types, and brands.
Stop using the battery if it has an odor, is abnormally hot, deformed, has its cover discolored, or has any other abnormalities.
When the battery is in use or charging, the above conditions may occur. Please remove the battery from the vehicle immediately or disconnect the charger and stop using it.
The battery charging voltage should be controlled below 16V, otherwise the battery will be damaged.
Before discarding the battery, please fully discharge the battery.

Note

The electrolyte in the battery is harmful to human skin and eyes. If the electrolyte leaking from the battery contacts your eyes, please do not rub it, rinse it with clean water immediately, and go to the hospital for treatment. If not handled properly, the electrolyte may damage your eyes.
