Compliance with minimum average discharge time: 1. Test 9 batteries for each discharge mode; 2. The average discharge value of 9 batteries is greater than or equal to the specified value of the minimum average discharge time, and the number of batteries whose single-cell discharge time is less than 80% of the specified value is not more than 1, then the battery electrical performance test of the batch is qualified; 3. If the average discharge value of 9 batteries is less than the specified value of the minimum average discharge time and (or) the number of batteries less than 80% of the specified value is greater than 1, then another 9 batteries are tested and the average value is calculated. If the calculation result meets the requirements of Article 2, the electrical performance test of the batch of batteries is qualified. If not, the battery electrical performance test of the batch is unqualified and no further testing.Safety performance requirementsLogo The battery body is marked with the following markings. 1. Model: R20P/D 2. Manufacturer or trademark: Sunmol ® 3. Battery polarity: "+" and "-" 4. shelf life of the deadline or the year of manufacture 5. Precautions for safe useStorage and expiration date 1. The battery should be stored in a well-ventilated, cool and dry place. 2. The battery should not be exposed to direct sunlight or placed in the rain for a long time. 3. Do not mix and stack the batteries with their packaging removed. 4. Store at 20℃±2℃, relative humidity 60±15%RH, the battery storage period is 2 years.

As the product technology is updated and the technical parameters are adjusted, the specifications will be updated at any time, so please contact ENITA in time to obtain the latest version of the specifications.

Liquid leakage resistance performance requirementsPrecautions for use 1. This battery is not rechargeable. If you charge the battery, there may be danger of battery leakage and explosion. 2. Make sure to insert the battery correctly according to the polarity (+ and -). 3. It is forbidden to short-circuit, heat, throw into fire or disassemble the battery. 4. The battery should not be over-discharged, otherwise the battery will swell, leak or the positive cap will top out and damage electrical appliances. 5. New and old batteries, batteries of different brands or models cannot be used together. It is recommended to use batteries of the same brand and the same model when replacing. 6. The battery should be removed when the electric appliance is not used for a long time. 7. Take out the exhausted battery from the electric appliance in time. 8. It is forbidden to weld the battery directly, otherwise the battery will be damaged. 9. The battery should be kept away from children. If swallowed accidentally, seek medical attention immediately.Conventional packaging Each 12 sections are packed into 1 inner box, 12 boxes are packed into 1 case. Also can be packaged according to customer requirements, the actual number of boxes marked by the box mark shall prevail.Keep your batteries where children can’t reach them. As with every small object, children may swallow batteries if they handle them incorrectly. Coin batteries are especially dangerous if they’re swallowed, as they could get stuck in a child’s smaller throat and cause suffocation. If that happens, immediately get to your nearest emergency room. Battery safety isn’t rocket science – it’s common sense. Be on the lookout for these pitfalls and you’ll be able to use your batteries optimally.Q1. How about your battery delivery time? A: Within 35 days after receiving your advance payment.
