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 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 Mod- ify It
Electrolyte leakage, generation of heat, ignition or rupture may result.
Do Not Short the Positive (+) and Negative (-) Con- tacts
Generation of heat, ignition or rupture may result. Do not place the battery pack together with articles such as neck- laces 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 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).
A lithium ion battery that is recyclable powers the product you have pur- chased.

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 recharging or normal use. This is completely nor- mal.
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 condi- tions. (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 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.
