| Identification | Warnings would better be marked on the surface of the battery which is tied up by certain |
| cells | |
| *Using the charger designated by the manufacture(AEC). | |
| *Don't throw the battery in fire or heat it. | |
| *Don't short-circuit. | |
| *Don't unpack the battery or change its structure. | |
| Pack design | * Battery pack should have sufficient strength and battery should be protected from mechanical shock |
| * No cell movement in the battery pack should be allowed. | |
| * No Sharp edge components should be inside the pack containing the battery. | |
| Charging | Charging current and charging voltage should be less than specified in the Product Specification. |
| The charger shall be designed to comply with Product Specification. | |
| It is dangerous that charging with higher curren or voltage than Product Specification may cause damage to the cell electrical,mechanical safety performance. |
2.Other The Chemical Reaction
Because batteries utilize a chemical reaction, battery performance will deteriorate over time even if stored for a long period of time without being used. In addition, if the various usage conditions such as charge, discharge, ambient temperature, etc. are not maintained within the specified ranges the life expectancy of the battery may be shortened or the device in which the battery is used may be damaged by electrolyte leakage. If the batteries cannot maintain a charge for long periods of time, even when they are charged correctly, this may indicate it is time to change the battery
