Factors Impacting Lithium Battery Cycle Life!
o Charging Cycles
Every lithium battery goes through cycles. One cycle involves a full discharge followed by a full recharge. Ideally, a battery should provide 500 to 1500 cycles. However, cycle life depends on several factors, including temperature and discharge level. A higher temperature or deep discharge can reduce cycles, lowering the lifespan. Remember, proper maintenance can enhance cycle life.
o Depth of Discharge (DoD)
DoD, another crucial term, refers to the percentage of battery drained before recharge. Lower DoD (20%-50%) typically extends battery lifespan. Hence, to improve longevity, avoid complete discharge.
o Overcharge Impact
Overcharging can damage the internal structure, affecting cycle life. Therefore, always disconnect after full charge.

Definition and Importance of DoD
DoD indicates how much a battery gets used before recharging. A lower DoD, like 20% to 50%, means only a small part of the battery gets used. This can help in extending the battery lifespan, making DoD a critical factor in managing lithium battery cycle life.
Impact of DoD on Lithium Battery Cycle Life
Lowering DoD helps prolong cycle life. So, it’s better not to wait until the battery fully drains before recharging. For instance, charging when the battery is half full (50% DoD) can help. In the long run, this habit can extend the battery’s lifespan, answering the question of how long can a lithium-ion battery last without charging. Hence, properly managing DoD contributes to longer lithium battery cycle life.
