Diagnostics functions
The BC-M50 checks connected battery packs for
abnormalities. An indicator will flash alternately in red and
green if a battery pack cannot be charged normally.
Refresh function (for nickel metal hydride battery
packs BP-M50/M100 only)
If a battery pack with remaining capacity is charged repeatedly,
the storage capacity of the battery may be reduced due to
memory effect (phenomena by which the remaining battery
capacity is memorized). To prevent against this memory
effect, a "refresh function" is provided to fully discharge a
battery pack before charging.

An indicator lights to show when a battery pack is charged less
