Precautions (Battery Pack)
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 leakage, 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 
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 
Electrolyte leakage, generation of heat, ignition or rupture may 
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 
If this product is subjected to a strong impact, stop using it im-
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-VZSU46AU) with your 
product. Use of battery packs other than those manufactured 
and supplied by Panasonic may present a safety hazard (gen-
eration of heat, ignition or rupture).
When the battery pack has become degraded, 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 be-
come 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 re-
charging only when the remaining power is less than approx. 
95% 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 
Risk of Explosion if Battery is replaced by an Incorrect Type.  
Dispose of Used Batteries According to the Instructions.
The battery pack may become warm during recharging or 
normal use.  This is completely normal.
Recharging will not commence if internal temperature of the 
battery pack is outside of the allowable temperature range (0 
°C to 50 °C {32°F to 122 °F}). 
 Reference Manual “Battery Power”) Once the allow-
able range requirement is satisfied, charging begins auto-
matically.  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.)
If the temperature is low, the operating time is shortened.  
Only use the computer within the allowable temperature 
This computer has a high temperature mode function that 
prevents the degradation of the battery in high temperature 
environments. (  
 Reference Manual “Battery Power”) A  
level corresponding to a 100% charge for high temperature 
mode is approximately equivalent to an 80% charge level for 
normal temperature mode.
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 package, brief-
case, etc., it is recommended that it be placed in a plastic 
bag so that its contacts are protected.
Always power off the computer when it is not in use. Leaving 
the computer on when the AC adaptor is not connected will 
exhaust the remaining battery capacity.
A lithium ion battery that is recyclable powers the product you have purchased.
