Questions about this item

How long before the 6800mAh lithium pack needs replacement?

The 14.4V 6800mAh lithium cell is rated for hundreds of charge cycles; typical service life is several years before capacity drops enough to require a new pack.

What stops the 97.92Wh battery from running longer under constant load?

The built-in over-voltage, over-discharge and short-circuit protection will cut output first when limits are reached during sustained high-drain use.

Does the 632g pack get hot or noisy during all-day operation?

No moving parts means silent running; normal warmth occurs under load but the protection circuits prevent excessive heat build-up during continuous use.
