Battery models include 18650 lithium battery, 26650 lithium battery, 14500 lithium battery and 16340 lithium battery.
1. 18650 lithium battery: 18mm in diameter and 65mm in length, it is one of the most commonly used battery models in bright flashlights.
2. 26650 lithium battery: diameter 26mm, length 65mm, 18650 lithium battery has larger capacity and longer life.
3. 14500 lithium battery: 14mm in diameter, 50mm in length, commonly used in small bright flashlights.
4. 16340 lithium battery: 16mm in diameter, 34mm in length, slightly larger than 14500 lithium battery, commonly used in small bright flashlights.
1000mV? Currently the unit of voltage is 1000 millivolts = 1 volt
Perhaps you are talking about the unit of capacitance, 1 000 mAh
The size of the 16340 also determines its capacity, unless it is High capacity can only be achieved with major technological advancements. The capacity of 16340 lithium battery is about 600 mAh and will not exceed 800 mAh at most. fake the label, the better, the capacity may not even be 500 ~~~
As for how long it takes to calculate the current of your charger, for example, if the current The approximate time to charge a 600 mAh 16340 battery is 600 mAh // 300 mA = 2 hours, plus 1.5 times the constant voltage time. The lower the charging current, the lower the multiple. Generally, 1.5 times is considered a longer time.
The last thing to remember is that lithium batteries need to be charged automatically! It cannot be charged all the time. It is better not to use the charger which has to calculate the time. The word “undesirable” ~~~
