38Wh capacity at 11.1V

Questions about this item

How long before the 38 Wh lithium-ion cell needs replacing?

The 11.1 V 38 Wh pack is rated for a typical lithium-ion service life; with daily charge cycles expect to replace it after a few years when run-time noticeably shortens.

What stops the battery from running longer on a single charge?

The 38 Wh capacity is the hard limit — once the cells deliver their rated watt-hours the system must recharge.

Does the 11.1 V pack get hot or noisy during all-day use?

The battery has no moving parts so it stays silent; warmth is normal under load but stays within safe lithium-ion operating temperatures.
