Questions about this item

When will the 3600mAh Ni-MH pack need replacing?

The battery pack carries a 1-year specification; plan a replacement after roughly one year of regular use.

What limits runtime during continuous operation?

The 21.6Wh capacity sets the energy ceiling, so sustained use ends when that charge is depleted.

How much heat does the 6.0V pack produce when running all day?

Normal Ni-MH chemistry generates moderate warmth under continuous load; the pack includes overcharge, over-discharge, over-voltage and short-circuit protection to keep temperatures in check.
