Skip function for fully charged batteries
If a fully charged battery pack is attached to the BC-M150,
nothing happens to the battery pack and the indicators show the
charging of the pack is complete.
Refresh function (for nickel metal hydride battery
packs BP-M50/M100 only)
The BC-M150 is provided with the refresh function to clear the
memory effect (phenomena by which the remaining battery
capacity is memorized) to fully discharge a battery pack before
charging.
Supply of up to 100 W of DC power
The BC-M150 can supply up to 100 watts of DC power to an
external device connected through an optional DC connecting
cable.
Cooling fan
An internal cooling fan turns on whenever the BC-M150 is
charging a battery pack or supplying power to an external
device.
• This unit is designed for charging Sony lithium-ion battery
packs (BP-L40A/L60A/IL75/L90A) and the nickel metal
hydride battery packs (BP-M50/M100).
• The DC-L1 (NP-1B adaptor) and DC-L90 (BP-90A
adaptor) cannot be used with this unit to charge nickel-
cadmium battery packs.
Charging system
Charging system of lithium-ion battery packs
When the BC-M150 is used to charge four lithium-ion battery
packs, it first charges each connected battery pack to 80%
capacity, in sequence. It then simultaneously charges all battery
packs to 100% capacity. In this way, it achieves more efficient
and faster charging than conventional systems in which each
battery is charged to 100% capacity before the next battery is
charged. Details about the new system and the charging times
are given below.
