Do Not Use with Any Other Product
The battery pack is rechargeable and was intended for
the specified product. If it is used with a product other
than the one for which it was designed, electrolyte leak-
age, generation of heat, ignition or rupture may result.
Do Not Charge the Battery Using Methods Other Than
Those Specified
If the battery is not charged using one of the specified
methods, electrolyte leakage, generation of heat, ignition
or rupture may result.
Do Not Throw the Battery Pack into a Fire or Expose It
to Excessive Heat
Generation of heat, ignition or rupture may result.
Avoid Extreme Heat (Near the Fire, in Direct Sunlight,
for Example)
Electrolyte leakage, generation of heat, ignition or rupture
may result.
Do Not Insert Sharp Objects into the Battery Pack,
Expose It to Bumps or Shocks, Disassemble, or Modify It
Electrolyte leakage, generation of heat, ignition or rupture
may result.
• If this product is subjected to a strong impact, stop using
it immediately.
Do Not Short the Positive (+) and Negative (-) Contacts
Generation of heat, ignition or rupture may result.
• Do not place the battery pack together with articles such as
necklaces or hairpins when carrying or storing.
Do Not Use This Product with a Battery Pack Other
Than the One Specified
Use only the specified battery pack (CF-VZSU51W/CF-
VZSU52W) with your product. Use of battery packs other than
those manufactured and supplied by Panasonic may present
a safety hazard (generation of heat, ignition or rupture).
When the Battery Pack Has Deteriorated, Replace It
with a New One
Continued use of a damaged battery pack may result in
heat generation, ignition or battery rupture.
Do not touch the terminals on the battery pack. The
battery pack may no longer function properly if the
contacts are dirty or damaged.
Do not expose the battery pack to water, or allow it to
become wet.
If the battery pack will not be used for a long period of
time (a month or more), charge or discharge (use) the
battery pack until the remaining battery level becomes
30% to 40% and store it in a cool, dry place.
This computer prevents overcharging of the battery by
recharging only when the remaining power is less than
approx. 95% (when Economy Mode (ECO) is enabled:
75%) of capacity.
The battery pack is not charged when the computer is
first purchased. Be sure to charge it before using it for
the first time. When the AC adaptor is connected to
the computer, charging begins automatically.
Should the battery leak and the fluid get into your
eyes, do not rub your eyes. Immediately flush your
eyes with clear water and see a doctor for medical
treatment as soon as possible.
NOTE
The battery pack may become warm during recharg-
ing or normal use. This is completely normal.
Recharging will not commence if internal tempera-
ture of the battery pack is outside of the allowable
temperature range (0 °C to 55 °C {32 °F to
131 °F}). (
Reference Manual
“Battery
Power”) Once the allowable range requirement is
satisfied, charging begins automatically. Note that
the recharging time varies based on the usage
conditions. (Recharging takes longer than usual
when the temperature is 10 °C {50 °F} or below.)
In high-temperature environments, the battery takes
longer to fully recharge. In low-temperature environ-
ments, the battery takes longer to fully recharge and
the operating time is shorter. Only use the computer
within the allowable temperature range.
The battery pack is a consumable item. If the
amount of time the computer can be run by using a
particular battery pack becomes dramatically
shorter and repeated recharging does not restore
its performance, the battery pack should be
replaced with a new one.
When transporting a spare battery inside a pack-
age, briefcase, etc., it is recommended that it be
placed in a plastic bag so that its contacts are pro-
tected.
Always power off the computer when it is not in
use. Leaving the computer on when the AC adap-
tor is not connected will exhaust the remaining bat-
tery capacity.
