Satisfaction Standard:
1. 9 pieces of battery will be tested for each discharging standard;
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. Then the batch battery performance test qualified.
3. If nine section of the battery discharge average less than the specified value of minimum average discharge time and (or) is less than the specified value of 80% of the battery number more than 1, we should take another 9 batteries to test again and calculate the average. Calculation results conform to the requirement of article 2, the batch battery performance test qualified. If it does not conform to the requirement of article 2, the batch battery performance test is unqualified, and no longer test.

Cautions
Signs
The following markings will be printed, stamped or impressed on the body of battery:
1. Designation: R03P/ AAA
2. Manufacturer or trademark: Sunmol ®
3. Polarity: "+"and"-"
4. Expiration date deadline or manufacturing time
5. The attention notes for safe use.
Cautions for Use
1. Since the battery is not manufactured for recharging, there are risks of electrolyte leakage or causing damage to the device if the battery is charged.
2. The battery shall be installed with its "+" and "-" polarity in a correct position, otherwise may cause short-circuit.
3. Short-circuiting, 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. Electrical appliances should be take out the battery when not in use for a long time
7. Exhausted batteries shall be removed from the compartment in order to prevent over-discharge.
8. Prohibit direct welding battery, otherwise it will damage the battery.
9. Battery are to be kept away from children. If swallowed, contact a physician at once.
