How long does a lithium battery last?

For instance, a lithium batteries regularly discharged to only 50% might last for 3,000 to 4,000 cycles, whereas the same battery consistently discharged to 80% could see its cycle life reduced to 1600-2000 cycles. The underlying rationale is that each cycle of discharge followed by recharge exerts wear on the battery’s internal mechanisms.
