Questions about this item

When will the 44Wh Li-polymer pack need replacing?

The battery is rated at 44Wh and 2950mAh; Li-polymer cells gradually lose capacity, so expect a swap when run-time drops below your needs.

What limits the 15V output during long sessions?

The 15V 44Wh pack delivers its rated energy until the cells deplete; sustained heavy loads will drain the 2950mAh capacity faster.

Does the 15V battery run hot or noisy in all-day use?

The sealed Li-polymer unit has no moving parts and produces no audible noise; it warms slightly under load but stays within normal operating temperatures.
