| Term | Meaning |
|---|---|
| Battery Cycles | Number of complete charge and discharge cycles |
| Cycle Limit | Maximum cycles before battery wears out |
| Capacity | How much charge battery can hold now |
Battery cycles tell a lot about health. A high number close to the cycle limit means the battery is old. Less capacity than original means it holds less power. Check these numbers to know if replacement is needed.
