Why the window matters
The battery window, the charge range you actually use, shapes both life and performance. Its value appears only when linked with charging and with use. Treating it alone misses how the three move together in genuine daily life.

Keeping it healthy
Check equipment status before use. Confirm billing stopped and verify the amount. Stop and report if a cable is damaged or connector loose. Save records so the window's behavior can be traced over a long time safely.
