1. The typical estimated life of a battery is about two or three years of charge cycles, whichever occurs first.
2. One charge cycle is a period of use from fully charged, fully discharged, and fully recharged again.
3. The cycle life is the number of complete charge/discharge cycles that the battery is able to support before that its capacity falls under 80% of its original capacity.so if the battery is discharged to 60% and then charged to 80%, it isn't a complete cycle.
4. Charging your device overnight is not a good idea, and that leaving your laptop battery connected to a charger when it is fully charged could lower battery life."Technically, you should not be charging your laptop battery for extended spans of time-so overnight laptop battery charging is a big no," it said.
