usb charging 9V battery structure design












USB charging 9V constant voltage output polymer lithium battery advantages

• i. Economical and practical
• 1. Save money
• it can be charged with a mobile phone charger (DC5V) without purchasing a dedicated charger.
• 2. Convenient
• for outdoor use, it can be directly charged by mobile power supply.
• 3. Durable
• use high-quality polymer lithium battery with a service life of more than 1,000 times
• 4. Beautiful
• red light display when charging, Green Light display after charging
• II. Security performance
• 1. Fire prevention
• the Shell uses fireproof material to prevent battery explosion and fire caused by external fire.
• 2.0v storage and activation
• during the transportation and storage of the battery, there is no voltage output at the 9V output terminal. When it is used for the first time, the 9V voltage is output only when it is charged and activated, which prevents the battery from explosion or fire caused by short circuit during transportation or storage.
• 3.9V constant voltage output
• the output voltage of the battery is constant at 9V during use, ensuring the test accuracy and sensitivity of the battery equipment.
• 4. Short circuit protection
• 0.2 ms when the load is short-circuited to protect against battery explosion or fire when the load is short-circuited
• 5. Charging protection
• overcharge Protection is implemented when the battery is charged to prevent battery performance degradation caused by overcharge, or battery explosion or fire.
• 6. Discharge protection
• over-discharge protection is implemented when the battery is discharged to prevent battery performance degradation caused by over-discharge, or battery explosion or fire.
• 7. Temperature control protection
• when the internal temperature of the battery is too high, it can be protected to prevent battery explosion or fire caused by too high temperature.
• 8. Polarity dislocation protection
• protection is realized when the polarity of the battery is wrong to prevent battery explosion or fire caused by improper use.
