warranty of Power-Xtra GROUPE INTERNATIONAL LIMITED
• Any matters which are not covered in this specification should be negotiated between the customer and Powe-Xtra.
Product Cautionary Statement and Disclosure
User manual
Warranty period of battery and Quality guarantee
Power-Xtra GROUPE INTERNATIONAL LIMITED, Ltd will not take any responsibility for the problems caused by incorrect
operation beyond the specification.
Note(1):
The battery might be at an over-discharged state because of its self-discharge characteristics if the battery is not
used for long time. In order to prevent over-discharging, the battery should be charged (at least once every three months)
periodically to maintain the voltage between (3.7V and 3.9V)*N ((n represents the number of series of cell)).
Note(2):
Power-Xtra GROUPE INTERNATIONAL LIMITED, Ltd will not take any responsibility for the problems caused by
improper use of PCM, battery pack, RC model and charger.
Note(3):
It is necessary to use the charger with protection balanced function to charge if the finished battery without PCM.
Note(4):
Power-Xtra GROUPE INTERNATIONAL LIMITED, Ltd will not take any responsibility for products beyond the warranty
period.
Note(5):
The charging current can’t exceed the maximum charging current in this specification; The charging with higher
current than recommended value may caused the problems of performance of charge & discharge, mechanical and safety,
and may lead to fever or leakage. The maximum charging voltage can’t exceed this specification.
Note(6):
The cell shall be discharged at less than the maximum discharge current specified in the Product Specification
；
High discharging current may reduce the discharging capacity significantly or cause over-heat.
Note(7):
Power-Xtra will not take any responsibility for battery damaged resulting from the client assembly after the products
were accepted.
• Stop using the battery immediately whenever it deforms, swells, leaks.
• Check the total output of the battery pack if the appearance is normal. Within one month of shipment, the total output is
within the standard as specification sheet shows, confirmed it is OK if in this range;
• Once the total voltage output is confirmed OK, test each cell voltage. Within one month of shipment, the standard of the
single cell output is in the range of 3.70V ~ 3.96V, and it is OK again if it is in this range;
• Once the total voltage and cell voltage are confirmed OK, test the total internal resistance through the discharge wire, if its
total internal resistance standard is within the standard range as specification sheet shows, it is OK for normal using.
• The battery might be in over-discharge status because of its self-discharged characteristics if no battery operation for a
long time. To prevent over-discharge occurs, the battery should be charged regularly to maintain its power between 30%
~60%. Over-discharge will lead to the loss of battery function;
• Battery long-term storage process, the remaining capacity should be between 30 to 60%, about 50% at best status. High
voltage storage conditions will accelerate the self-discharge, increase the side reaction products, and may damage the
battery performance;
• Battery long-term storage temperature is 0
℃
~ 30
℃
, for the storage period of more than 3 months, battery pack needs to
be activated before use. Activation means that charge the battery pack with a balanced charger, charging until the
electricity is displayed at 100% SOC, then discharged at a current of 0.2CmA to the voltage protection, and then charge the
battery to about 50% SOC with the balance charger;
• Do not discharge battery pack with less than 3.2V * N (N refers to the number of batteries in series) otherwise it will lead to
the battery pack performance degradation and shorten its cycle life;
• Recommend to remain no less than 20% of the battery electricity after the end of using.
