Precautions
On the battery charger
• The BC-M150 can be used exclusively with Sony Lithium-
ion Battery Packs and Nickel Metal Hydride Battery
Packs. Using this unit to charge other types of battery
packs or ones made by other manufacturers may result in
smoke or fire.
• Use the BC-M150 in an operating environment of 10˚C to
30˚C (50˚F to 86˚F). Since charging is difficult at low or high
temperatures, we recommend that battery packs be charged
between 10˚C and 30˚C (50˚F and 86˚F).
• Avoid using or storing the BC-M150 in dusty places or places
with corrosive gases.
• Avoid using or storing the BC-M150 in places exposed to
direct sunlight.
• Do not cover the ventilation holes.
On battery packs
• Even when fully charged, battery packs gradually lose their
charge naturally. Use the battery packs as soon as possible
after charging.
• Carry and store battery packs by installing them in your
equipment or by repacking them using the original packing
material.
• To prolong the life of battery packs, store them in a cool place
(about 20˚C (68˚F)), and charge in a place with an ambient
temperature between 10˚C and 30˚C (50˚F and 86˚F).
• When temperatures are 10˚C (50˚F) or lower, the
performance of a battery pack suffers and the usable time of a
battery pack becomes shorter. To get the longest usable time,
warm the battery packs to room temperature (about 20˚C
(68˚F)) before use.
• Carrying a spare battery pack is recommended.
• When charging with an ambient temperature between 30˚C
and 40˚C (86˚F and 104˚F), battery packs may not be charged
to its full capacity (printed on the surface of the battery pack).
Even if the charge indicators (or the display) show(s) that the
full charging is completed, actual charging amount may be
about 80% of full capacity.
