Why batteries lose health
Lithium-ion batteries wear with charge cycles, heat and being kept at 100% for long periods. A 3–4 year old laptop at 60–75% health is common. Brands like Lenovo, Dell, HP and ASUS offer a charge limit (around 80%) in their apps – turning it on slows wear.

Frequently asked questions
Is full charge capacity higher than design capacity possible?
Yes, on new batteries it can be slightly higher; health above 100% just means a very healthy battery.
How many cycles does a laptop battery last?
Typically 300–1,000 cycles before dropping to around 80%, depending on the battery and usage.
Does this work on a MacBook?
