Questions about this item

How long before the 46WH lithium-ion pack needs replacing?

The battery is a 100 % brand-new replacement rated at 46WH and 11.25V; typical lithium-ion cells last several hundred full charge cycles before runtime falls noticeably.

What limits runtime during a full day of continuous use?

The 46WH capacity at 11.25V sets the total energy available; sustained loads will drain the pack until the laptop initiates its low-voltage shutdown.

Does the pack run hot or draw extra power when the laptop is on all day?

Lithium-ion chemistry generates minimal heat during normal discharge, and the pack simply supplies the 11.25V the EliteBook 720, 725 or 820 G1/G2 expects.
