5.Important Notes（Warranty）

5.1No swallowing

Keep the battery out of reach of children. Never put batteries in mouth. If ingested, immediately seek medical attention.

5.2No recharging

Forbid using any other power supply to charge the battery. Recharging can lead to produce gas and internal short circuit, causing cell deformation, leakage, overheat, explode or catch fire.

5.3Do Not Dispose In Fire

The lithium will be melted when dispose in fire.

5.4Do Not Disassemble

Do not disassemble the battery or it will cause the damage of gasket or the separator, deformation, leakage, over-heat, explosion or firing will happen.

5.5Insert Batteries Correctly

Depending on the application device, incorrect insertion of batteries, with positive(+) and negative(-) poles reversed, may result in short circuits and the risk of heat generation, fire or explosion.

5.6Do Not Short-circuit 

Do Not Short-circuit. Do not keep or store the battery with metal or it will cause deformation, leakage, over-heat, explosion or firing.

Do not take several pieces of batteries from the packing box at one time or stock mixed, it can lead deformation, leakage, over-heat or firing.

5.7Do Not Mix Different Types Of Batteries

For some application, mixing different types of batteries, or new and old batteries, can cause over discharge due to difference in voltage and electrical capacities. This may lead to the risk of swelling or explosion.

5.8Do Not Weld Pin Or Wire Directly On The Battery

The lithium will melt when welding or cause damage of insulation material. This will lead deformation, over-heat, explosion or firing. If weld is needed, please contact Daily-max or professional welder.

6.Cautions

6.1Shaking、jumbling、Scatters or trampled batteries, may cause short circuits, heat generation, fire or explosion.

6.2 Install batteries, please be careful when operating, don't let the battery come into contact with metal objects could make the battery short circuit.

6.3Selecting suitable batteries as the operation instructions.

6.4Do not use or store the batteries in high-temp places like exposure sunshine or in car which in burning hot, it will lead deformation, leakage, over-heat, explosion or firing.

6.5Do not let the battery contact water or store in a wet environment or it will cause rust, deformation, leakage, over-heat, explosion or firing.

6.6The voltage may lower than target one by bad contact so pls keep 2N contact pressure.

6.7If any questions please contact Anyida.

7.Storage Environment

The storage environment should be clean, cool, dry, ventilation, do not close to high-temp or high moisture, the environment temp should 0℃-30℃, RH not exceed 75%.

8.Marking and Packing

8.1Sign Of Positive Pole 

Different brands can be as customers’ requests.

8.2Date Code

If customers need date code as IEC standard with 2 words:□□, the first one expresses year by 0-9, the second one expresses Jan-Sep by 1-9, O, Y, Z means Oct-Dec.

Examples:01 means manufactured in Jan-2020；     0O means manufactured in Oct-2020；

        0Y means manufactured in Nov-2020；     0Z means manufactured in Dec-2020。

Different date code can be made.

8.3Packing

Each 20pcs in a PVC tray, 10 trays(200pcs) be packed by PVC film, 12 small packages (2400pcs) in a outer carton..

If the batteries need to be with pins, the packing will be changed by product appearance

 

9.Discharge characteristics

With the progress of product technology, technical parameters, the specification will be updated too, please contact Anyida for latest specification.
