All rapid charge methods should be discussed with our engineer

We stipulate to charge less than 40% fully power for delivery, if the charge is more than 40%, the battery has a certain latent risk. For the charge requirement is over 40% which caused quality problem, we do not undertake any responsibility.

Our battery guarantee time: 12 months

During storage period the batch battery is requested by the 40% electric charge, the battery storage surpasses 3 months, we suggest charge 40% every 3 months .

The transportation and storage


In the transportation process the battery should maintain at clean, dry, and the well ventilated environment, and prevents the fierce vibration, the impact or the extrusion, prevents to be exposed to the sun and rain. Battery could be transported by automobile, train, steamboat ,airplane and other transportation vehicle .


5.2.1 Battery must be stored at -20 ~ +35 , (It is best at 15 ~ +25 ) and put in the clean, dry and ventilated place with relative humidity 85% max.. It must be kept away from corrodent substance, fire hazard and heat resource.

5.2.2 Storage placement way

The packed battery in a carton stack less than 5 layers, to guarantee that between the cell box has the good air circulation condition, please maintain between the carton above 5~10 cm distance, which prevents the safety incident caused by a pile of agglomeration to heat .


7.Warning and Security

To prevent the impact of equipment failure caused by the battery, and to make sure the security of circuit and battery set, please consider below things when design and produce the production equipment. Please put it into your instruction.


▲ Danger !

★ Against the following matters will result in battery leakage, heat, explosion, fire and serious personal injury! (1)Prohibited to throw the battery into fire or heat!

(2)Prohibited to collide or throw battery! (3)Don’t weld the lead on the battery directly.

(4) Don’t put the battery on a place which is more than 1.5 meter in case of dropping. Don’t drop it at the height of more than 1.5 meter.

(5) Don’t connect the positive pole and electrode pole directly of battery, such as leading wire. If the tab terminal of poles doesn’t set insulation covering, please don’t transport or store. Please don’t touch the metal necklace, key or any other conductive material. Please use special carton when transport or store.

(6) Must use the charger appointed by to charge batteries, and follow the instructors of .

(7) Prohibited to disassemble batteries. It will cause external or internal short circuit, and the exposed parts will have chemical reaction then result in very dangerous heat, explosion, fire or splash of electrolyte.


▲ Warning

(1) Don’t contact batteries with water, sea water or other oxidation reagents, which will cause rustiness and heat. If batteries get rusty, explosive decompression valve won’t work and will lead to explosion.

(2) Don’t over-charge batteries, that is, don’t continually charge batteries despite the designed charging time. If the batteries are not fully charged within the designed charging time, please stop to charge. The delay of charging time will lead to leakage, heat and explosion.

(3) NI-MH battery includes the colorless strong alkaline liquor (i.e. electrolyte), if the skin or clothes touch NI-MH battery liquor, please use the boron acid water or the vinegar acid water to clean, after that , with the clear water thoroughly flushes. Because the battery's electrolyte can corrode the skin.

(4) It is forbidden for more than 20 pcs batteries in series. Because it will result in leakage, getting shock or giving off heat.

(5) Don’t disassemble the battery, as it will result in short-circuit, leakage, giving off heat, catching fire and explosion.

(6) Don’t use the batteries when they are leakage, any color deterioration, distortion or other changes are found.

Otherwise it will get hot, catching fire or explosion may happen.

(7) Please keep the batteries and other electronic products related to battery away from baby, children, to avoid accident of swallowing of battery. If there is any accident, please go to see the doctor.

(8) To use new battery when the working time of the battery is far short from the initial working time, as the cycle life of this battery is finished.
