Fully charged battery skip function
If a fully charged battery pack is attached to the BC-M50, the
charging does not take place.
• This unit is a charger for Sony lithium-ion battery packs
(BP-L40/L40A/L60A/L90A) and Sony nickel metal
hydride battery packs (BP-M50/M100).
• The DC-L1 (NP-1B adaptor) and DC-L90 (BP-90A
adaptor) cannot be used to charge nickel-cadmium battery
packs.
When this unit is used to charge two lithium-ion battery packs
at the same time, charging of one battery pack starts when the
other battery pack is 80% charged. Under the conventional
charging system, charging of one battery pack did not start
until the other was 100% charged. This unit's new charging
system enables quicker charging of two battery packs.
