Accordance of shortest discharging time 1. Testing 9 batteries of each discharging way 2. The result of the average discharging time from each discharging standard shall be equal to or more than the average minimum time requirement; no more than one battery has a service output less than 80% of the specified requirement 3. The result of the average discharging time from each discharging standard shall be equal to or more than the average minimum time requirement, if one battery has a service output less than 80% of the specified requirement then take another 9 pieces to test again. This lot of batteries are qualified if the result meets the NO.2 provision. If not qualified then will not test again.Safety RequirementsSigns The following signs are on the battery body: 1. Model: LR14/C 2. Manufacturer and brand: Sunmol ® 3. Battery Poles: "+"and"-" 4. Expiry date or manufacturing date 5. Warnings.Normal Package Each 12 pieces in one inner box, 20 boxes in one carton.

Anti-leakage abilityCautions for using 1. This battery can’t be charged, leakage and explosion may happen when charging. 2. Make sure the battery is in correct position as + and -. 3. Short-circuit, heating, disposing of into fire or disassembling of battery is prohibited. 4. Battery can not be forced discharged, which leads to excess gassing and may result in bulging, leakage and de-crimping of cap. 5. New batteries and used ones can not be used at the same time. It is recommended to use the same brand when replacing batteries. 6. The battery should be taken out from the device which will not be used for a long time. 7. Exhausted battery should be taken out from the device. 8. Welding batteries are prohibited or it will cause damage. 9. The batteries should be kept from children, if swallowed, contact a doctor immediately.Storage and Expiry  1. Batteries should be put in cool, dry and with air-flowing places 2. The batteries should not be exposed in sunshine or in raining places. 3. Do not mix the batteries which without labels 4. Storing in 20℃±2℃, 60±15%RH condition. The storage time is 3 years.
