Important Battery Tips
1. How to use the battery with minimal deterioration
The battery is a consumable and, as such, its performance will gradually deteriorate. This deterioration is accelerated
under the following conditions.
When the battery is repeatedly charged
When the battery is used, charged or stored in a place with high temperature
To minimize deterioration of the battery and ensure a longer battery life, you must reduce the number of charges and
ensure that the temperature inside the battery does not become too high. Bear in mind the following points.
Charge the battery in a temperature range of 10°C to 30°C {50°F to 86°F}
In places where the outside air temperature is high, the temperature inside the battery will also become high. Do not
charge the battery inside a vehicle with all its windows closed and exposed to the hot sun or in other places where the
temperature is high.
This computer's battery will not be charged if its temperature is outside the allowable range. (At such a time, the battery
indicator blinks orange.)
We recommend charging the battery no more than once per day
Recharging the battery after every small use raises the total number of battery charges and speeds battery deterioration.
To lower the total number of battery charges, we recommend recharging the battery no more than once per day or when
the remaining charge drops to 10% or less.
With this computer, in order to reduce the number of charges, the battery will not be recharged immediately after it has
been fully charged unless the remaining charge has fallen to less than 95%

Models with Economy mode Setting Utility (
When Economy mode is disabled : less than 95%
When Economy mode is enabled : less than 75%
Charging the battery while the computer is powered off is recommended
If the computer's power is on, the temperature inside the battery rises due to the effects of heat from the CPU and other
components. We recommend that you only charge the battery when the computer is powered off.
