Questions about this item

How long until the 600mAh Ni-MH pack needs replacing?

Typical life is several hundred charge cycles; capacity will gradually drop below useful runtime after 2-3 years of regular daily use.

What limits runtime during continuous operation?

The 2.16Wh capacity sets the hard ceiling; sustained high-drain devices will deplete the 600mAh cell faster than intermittent use.

Does the 3.6V battery get hot during all-day use?

Normal operation stays near ambient temperature; only rapid charging or a short-circuit fault triggers noticeable warmth thanks to built-in protection circuits.
