Technical Requirements

Discharge capacity

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.

Childproof your batteries

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.
