10. Storage
The place of preserving the battery must accord with those following requirements: Indoor, the temperature of environment is
between -5℃～35℃, the relative humidity is ≤75%, the place must be clean, dry and ventilate; avoid contacting to the
corrosives; keep far away from fire and heat; keep the battery 50%～60% charge state; avoid over-discharge, the battery should
be charged once every three months when preserved.
11. Battery Maintenance
(1) Be sure to charge the new battery fully before using for the first time .The battery will reach its max capacity after 3～5 times
of full charge and discharge.
(2) The battery should be used in the ventilating and dry environment. Stay away from fire.
(3) The best working temperature range for the battery is 15℃～40℃.Beyond that, there will be effect on the battery's normal
working.
(4) Don't short circuit the battery by connecting the cathode and anode, in case of any danger.
(5) Don't wash the outer shell of the battery with impregnate .In case of fire, please use Carbon Chlorine to put out fire instead
of CO2.
(6) If the battery goes wrong, please deliver that to the factory service center or relevant organization for proper disposal.
12. Dos & Don'ts
In case of leakage, heat, fire, performance decrease etc, please use the battery according to the following regulations. Our
company won’t take any responsibility for any mis-operation not according to this specification.
(1) First plug the input end of the charger into the battery charging socket, and then connect with AC
power.
(2) When charging, it is normal when the red indicator is on. When the green indicator is on, the battery is
fully charged. Please stop charging the battery.
(3) After finishing charging, please disconnect the plug with the AC power first and then disconnect the
plug connecting the battery.
(4) It is prohibited to connect the idle charger (when not connecting it with the battery) with AC power
supply for a long time.
(5) It is allowed to charge the battery either taking it off the electric appliance or directly on the appliance.
(6) When charging the battery directly on the electric appliance, please don’t start the electric equipment
to avoid damaging the charger.
(7) Please charge the battery in a ventilated place far away from fire. Use matchable proper charger only.
(8) For the sake of safety, be sure to charge the battery where children cannot reach.
(9) Handle with care, do not shake.
(10) Don’t immerse the battery in the water or other liquid, in case of damp. Especially on rainy days,
prevent the water from going into the controller and motor to avoid short- circuit.
(11) Don’t connect the anode and cathode to avoid short circuit.
(12) Please charge the battery with the Special charger provided by HiPower.
(13) Don’t dismantle the battery, otherwise it may cause inner short-circuit and then decomposition of the
inner material, fire and even explosion. In addition, dismantling the battery may cause the leakage of the
electrolyte, which will have some bad effects on human body. If the electrolyte is spattered onto skin, eye
and other parts of the body, please wash with clean water immediately and go to the doctor at once.
(14) Don’t dispose the battery with fire, avoiding accidents it might cause.
(15) If the battery is damaged, distorted or there is leakage of the electrolyte or the taste of electrolyte and
some similar abnormal phenomena, don’t use the battery any more. Please deliver that to the factory
service center or relevant organization for proper disposal. In addition, battery with electrolyte leakage
should be far away from fire.
(16) The battery provider should be responsible for replacing and installing the battery and the consumer
shouldn’t replace that at will.
(17) The consumer shouldn’t dismantle the battery at will. Or our company won’t take any responsibility.
(18) When using the battery, the consumer need to discharge the battery to the low voltage of the
controller, then charge it with the matchable charger.
13. Dos & Don’ts-- Transportation
(1) The battery is suitable for being transported by truck, train, boat and plane. During transportation,
please avoid solarization, drench and serious shake.
(2) The battery must be packed in insulation shockproof materials with labels saying ' Fragile'.
(3) Put the battery in the upright position. A sticker indicating 'Don’t upside down' is needed.
(4) Handle with care in transit.
(5) Don’t place any heavy objects on battery pack to avoid damaging the battery pack because of the
impact.
(6) Don't mix-transport with flammable or explosive consignment, or metal objects with sharp end.
(7) Outer packing should be marked ' Away from moisture, water, and fire'.
