Suggestions for Long-term Storage：
• Temperature
The battery can be operated at a temperature of-20 ℃to 60 ℃/-4°F to 140F, and a temperature
between 10℃to 35℃/50°F to 95°F is ideal for long-term storage. Store in a fireproof container and
away from children.
• Capacity
For a longer-lasting product, it is best to store your battery at a 50% charge level and recharge
every three months if it is not going to be used for a long time.
CHARGING METHODS
THE VOLTAGE WHEN CHARGING & DISCHARGING
Based on the characteristics of Lithium lron Phosphate (LiFePO4) batter- ies, the voltage measured
by all LiFePO4 batteries during charging/dis- charging is not the real yoltage of the battery.
Therefore, after charging/discharging and disconnecting the battery from the power source, the
voltage of the battery will gradually drop/increase to its real voltage.
If you need to test the real voltage of the battery, please disconnect all the connections to the
battery and test its voltage after putting it aside for over 30 mins.
Tips When Testing The Battery Voltage by A Multimeter
①Put the red probe (+) tightly on the positive terminal (not the post bolts), and the black probe (-)
on the negative terminal.
②Do not touch the metal part of the probes with your hands during use.

Battery Charging Logic
The material characteristics of the LiFePO4 battery determine that its charging curve is obviously
different from that of a lead-acid battery. Compared with a lead-acid battery, the LiFePO4 battery
has a simpler charging process and mode. Therefore, it is recommended to select LiFePO4 for your
charging mode.
If LiFePO4 mode is not available, please refer to the recommended parameters on Page 10 for
setting.
LiFePO4 Battery Charging Mode
•CC (Constant Current) Phase (T1)
In the beginning, a discharged battery will be charged with a constant current and voltage will be
climbing steadily until reaching the constant voltage setpoint which varies for different charging
methods.
•CV (Constant Voltage) Phase (T2)
The battery maintains a constant voltage during this phase while the current gradually decreases to
6A (0.02C) which is also known as tail current. At this point, the charging is cut off and the battery is
fully charged.
SOLAR PANEL(S) & CONTROLLER
Solar Panel
• Recommend Power: ≥900W
• The battery can be fully charged in one day (with effective sunshine 4.5hrs/day) by 900W
solar panels.
• It may take more than one day to fully charge the battery by 900W solar panels since the
duration and intensity of light would be a great factor for their charging efficiency.
Controller
Recommend Charging Current:
40A(0.2C)
The battery will be fully charged in around 5hrs to 100% capacity
100A(0.5C)
The battery will be fully charged in around 2hrs to around 97% capacity

Recommend Charging Mode：12V (14.6V) LI (LiFePO4)
Controller Settings
Refer to the below parameters if you need to manually set up your controller.
As different types of batteries have different charging modes (refer to Page 09), it is recommended
to set only the following parameters for LiFePO4 batteries. The settings for other types of batteries
do not apply to LiFePO4 batteries except for the following settings.

② It's recommended to disconnect the charger from the battery after fully charging.
ALTERNATOR/GENERATOR
TEZE battery can be charged by an alternator or generator.
If the alternator/generator supports DC output, a DC-to-DC charger needs to be added between the
battery and the generator; if the alternator/gen- erator supports AC output, please refer to the
recommendations in "Battery Charger" above to add a suitable battery charger between the battery
and the generator.

HOW TO ESTIMATE THE BATTERY CAPACITY
STATE OF CHARGE (SOC)
The battery capacity could be roughly estimated by its rest voltage (not charging/discharging
voltage). As there are subtle differences in the voltage of each battery, the below parameters are
for reference only.
Rest Voltage : The voltage needs to be tested at rest (with zero current) after 30 mins of
disconnecting from the charger & loads.
