Tamuz - Model P/N: CR2025-A00 - Primary Lithium Battery

5. Important Notes (Warranty)

5.1 Do Not swallow

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

attention.

5.2 Do Not recharge

Forbid using any other power supply to charge the battery. Recharging can lead to produce gas and internal

short circuits, causing cell deformation, leakage, overheat, explode, or catch fire.

5.3 Do Not Dispose In Fire

The lithium will be melted when dispose in fire.

5.4 Do 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.

5.5 Insert 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.

5.6 Do 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

5.7 Do 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.

5.8 Do 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, overheat, explosion or firing. If weld is needed, please contact Tamuz or professional welder.

6. Cautions

6.1 Shaking, 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.

6.3 Selecting suitable batteries as the operation instructions.

6.4 Do 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.

6.5 Do not let the battery contact water or store in a wet environment or it will cause rust, deformation, leakage,

over-heat, explosion, or firing.

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

6.7 If any questions please contact Tamuz.

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

8.1 Sign Of Positive Pole

8.2 Date Code(Date code is selective and need to pay extra charge)

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: 81 means manufactured in Jan-2018 ;  means manufactured in Oct-2018 ;

8Y means manufactured in Nov-2018 ; 8Z means manufactured in Dec-2018.

* Remark: Different date code can be made.

8.3 Packing

Each 20pcs in a PVC tray, 25 trays (500pcs) be packed by PVC film, 6 small packages in one inner box,

2 inner boxes (6,000pcs) in an outer carton.

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