Mike,
The KX3 uses 8 AA size batteries. Access to the batteries is easy -
loosen the 4 thumbscrews on the corners and separate the 2 halves.
You do not have access directly to the battery terminals. The KXBC3
option will keep NiMH batteries charged. Without that option, the
batteries must be removed for charging.
It is not like the K2 which uses an SLA (Sealed Lead Acid - aka Gell
Cell) battery. Alkaline AA cells can be used as well as NiMH, and
although they are not rechargeable, they are commonly available in case
of an emergency.
Yes, there is a series diode for reverse polarity protection. The
internal voltage will be about 0.3 volts less than the external supply.

Dont have a KX3 (yet) but curious about the points below if someone can
enlighten me?
Is access to terminals and exchange of int. battery for KX3 as inconvenient as it is for the K2?
Is there a series diode on the ext. power connector that will cause forward
bias voltage drop if powered by external battery?
