Questions about this item

When will the 6-cell lithium-ion pack need replacing?

The 4400 mAh cells degrade with each charge cycle; expect service life of one to three years depending on daily depth of discharge.

What limits runtime during a long work session?

The 48 Wh capacity sets the hard ceiling; sustained loads drain the pack faster than light browsing.

How warm does the battery get under all-day load?

The built-in smart chip throttles current if temperature rises, keeping heat within safe limits for the 10.8 V chemistry.
