Storage:

• To ensure the battery capacity to maintain the level recommended batteries and battery packs-20 To 35Under low humidity , corrosive gas storage conditions
• Avoid storing batteries at high temperatures or high humidity , otherwise it will lead to battery leakage , rust , and lower capacity.
• May lead to long-term storage batteries and battery capacity decreases, and the need1-3Charging/Discharge cycles to reach the highest discharge capacity.
• Three months after placing the battery needs charging and discharging cycle time .

Warning :

• Allowed to reverse charging , the battery should be connected by polar accurate , can not reverse .
• Do not allow short circuit , otherwise it will cause permanent damage .
• The battery can not use under extreme conditions , such as: extreme temperature , deep cycling , extreme overcharge and over discharge.
• Keep batteries stored in a cool dry place , if a large number of battery storage or shipping batteries must first discharged.
• Do not solder directly to the battery .
• If the battery has noise , heat, leakage and other anomalies , please stop using it immediately.
• Do not fire or attempt to open the battery may burn or harmful substances.
• Do not allow the use of half of the old batteries or batteries with new batteries together , or will cause over-discharge .
• Not cut to remove the battery housing and the outer casing .
• Do not allow the battery into the water.

Note:

• Should charge the battery before use good power .
• Charging method according to our technical specifications.
• Use the appropriate charger.
• Avoid the use of sealed battery should provide appropriate ventilation , otherwise the battery may produce hydrogen in the presence of an ignition source, the situation will explode .
• Do not attempt to separate or bear squeeze and collision battery pack could cause the battery to generate heat , flaming , alkaline electrolyte spill will damage the skin and eyes will corrode clothing.
• The battery should be away from the kids , if they are swallowed, contact your doctor immediately required treatment .
• When the battery is not in use, should be removed from the device .
• When using the new battery after the first long-term storage or use , fully charged before use .
• When the battery is hot, do not touch until it cools down.
• When the battery is found to decrease energy use should switch off the device , in order to avoid over-discharge .
• When removing the battery pack , you should hold the battery pack terminal and can not hold the line .
• After the battery if the battery is hot , before charging again to be put in the ventilation without direct sunlight cool.
