About 21700 Battery first charge
21700 protected batteries have an electronic circuit. The circuit is embedded in the cell packaging (battery casing) that protects the cell from “over charge”, heat or “over discharge”, over current and short circuit. A 21700 protected battery is safer than an 21700 unprotected battery (less.
A 3.7v a 5100mAh 21700 stores about 3 aH to max of 5 aH. It can store about 15 to 20 watt hours. A small air conditioning unit that can cool about 9000 BTU uses about 1100 watts per hour.
The way you recharge your battery impacts the life of the battery. If you can measure it, you want to deplete from 3.7v down it to about 3v before you recharge. If you are not sure, use the device until it indicates a battery.
Recharge cycles vary and are limited. Think of it like a bucket. The trick is that the bucket also gets filled with other junk over time, so there is less room. As the battery is reused.A 21700 battery usually takes 1.5 to 4 hours to charge. Charging time depends on the battery capacity and charger speed. Fast chargers can charge quickly but may affect battery health.
