Precautions
On the battery charger
• Use the BC-L120 in an operating environment of 0
°
C to 40
°
C
(32
°
F to 104
°
F). Since charging is difficult at low
temperatures, we recommend that battery packs be charged
between 20
°
C and 30
°
C (68
°
F and 86
°
F).
• Avoid using or storing the BC-L120 in dusty places or places
with corrosive gases.
• Avoid using or storing the BC-L120 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.
Lithium-ion battery packs are free from memory effect.
There is no need to discharge them fully before recharging.
If the usable time of a battery pack becomes very short, it is
time to replace it with a new one.
