Precautions - Sony BC-L70 Operation Manual

Precautions

On the battery charger
• Use the BC-L70 in an operating
environment of 0°C to 45°C (32°F to
113°F). Since charging is difficult at low
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-L70 in
dusty places or places with corrosive
gases.
• Avoid using or storing the BC-L70 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.
22 Precautions
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.
