Toshiba PA3904U Laptop Battery Announcements：
1. Please choose the same model of the power charger or the manufacturer-specified model, avoiding using distrusted power chargers so as not to burn the notebook by unstable power supply;, avoiding using other packaging materials to wrap the power adapters which would result in cooling difficulties, keeping good ventilation and heat dissipation for the battery and power adapter.
2. When use initially, you had better complete charge and discharge two or three cycles in order to fully activate the lithium-ion in the battery in order to achieve the synchronization with the power detection program.
3. Cut off the power and shut down the computer, then put the battery into the computer, plug in the power supply to start charging. (Note Do not handling the battery when the power adapter plugged in, because this may burn your computer accidently.
4. The charging time is approximately between 4-8 hours, depending on the differences on battery capacity and design. When charging is completed, the charging indicator light will go out or turn green then you had better unplug the power supply.
5. You had better not charge intermittently, that’s to say you can’t plug the power supply back and forth during a short time. Also you had better charge under the condition of shutdown.
6. Do not mix the transformer and the power supply, there are some differences between the operating voltage and charging voltage for each electronic product, if used by error, it might damage the battery or even burn the machine.
7. When charging is completed, you will have got a better performance after 30 minutes.
8. Computer batteries are mainly made from lithium-ion and its biggest advantage is no memory effect, so you do not have to worry about this issue, if the power does not run out, the battery can also be charged, but we recommend that you use the battery till its lack of electricity and appearing system warnings occasionally, if so, it can help the reliability of the battery.
