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 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 sections of the battery discharge average is less than the specified value of 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.

9. Signs
The following markings will be printed, stamped, or impressed on the body of the battery:
1. Designation: R03P/ AAA
2. Manufacturer or trademark: Daily-max
3.Polarity:“+”and“-”
4. Expiration date deadline or manufacturing time
5. The attention notes for safe use.
10. 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 the correct position, otherwise may cause a short circuit.
3. Short-circuiting, heating, disposing of into fire, or disassembling of battery is prohibited.
4. The battery can not be forced to discharge, which s to excess gassing and may result in bulging, leakage, and de-crimping of the 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 taken 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 is to be kept away from children. If swallowed, contact a physician at once.
11. Normal Packing
Every 2 or 3 and 4 batteries or according to customer requirements with
transparent membrane after hot shrinkage, each 60 knots in 1 inner box,
20 boxes into 1 box.
12. Storage and shelf life
1. Batteries should be stored in a ventilated, cool, and dry place。
2. The battery should not be exposed to direct sunlight for a long time or in the rain。
3. Not to mix the removed packaging battery stack together.
4.Stored at condition of tempreture20℃±2℃, relative humidity 60±15%RH, the battery shelf life is 2 years。
13. Typical discharge curve
Discharge environment:20℃±2℃,RH60±15%
