matters need attention
1 without adult supervision. Do not let the children replace the batteries. Children should not use a small battery like AAA:
- Don’t bring anything new. Mix old batteries or different models, especially do not mix dry batteries and rechargeable batteries:
- Do not try to use heating, charging or other methods to regenerate the battery to avoid dangers;
- Do not short-circuit the rechargeable battery, otherwise it will damage the battery and heat, and make the battery burn.
- Do not heat the battery or throw the battery into the water or in the fire, put the battery into the water will make the battery invalid, put the battery into the fire will make the battery break, or
- Do not remove the battery, or try to penetrate the battery with a sharp weapon, because the electrolyte inside the battery can damage the skin and clothes.
- After using electrical appliances, disconnect the power switch to avoid heat and fire:
- The battery shall be removed and stored from electrical appliances that have not been used for a long time. Charge once every 3 months or so:
- The battery should be kept in cool, dry places to avoid direct sunlight:
- Nickel charger and lithium charger shall not be mixed:

- USB The interface can only be directly inserted into the U disk to play music, and cannot be used by external extension lines.
- Not reverse charging, reverse charging is equivalent to overdischarge. Overdischarge can cause adverse reactions inside the battery, causing serious damage to the battery, and producing a large amount of gas, which may lead to the chemical leakage of the rechargeable battery.
- Do not place rechargeable batteries under rain water. Rain water can conduct electricity. When the battery is placed under the rain, it is likely to short circuit, heating the battery due to the instantaneous high current discharge. Damage to the battery or is in a dangerous condition.
- If the battery cannot be stored in high temperature or high temperature environments, the reaction of the battery itself will intensify. Therefore, it cannot provide enough capacity for second- hand electrical appliances. In addition, under high temperature and high humidity conditions, the aging rate of the batteries will be greatly accelerated, as well as the electronic components (except for high-temperature batteries).
- Do not insert the positive and negative electrodes of the battery as the battery will expand or rupture:
