Thermals noise and power in normal use

The Li-ion cells run at 11.25V with a 50WH capacity and produce no audible noise during operation. Heat output stays low under typical office workloads. For best longevity, fully charge and discharge two or three times initially, avoid continuous adapter use while on battery, and store above 80% charge if removed for extended periods.
