The ES400 is equipped with a memory backup battery which automatically charges from the fully-charged main
battery. When using the ES400 for the first time, the backup battery requires approximately 36 hours to fully
charge. This is also true any time the backup battery is discharged, which occurs when the main battery is
removed for several hours. The backup battery retains RAM data in memory for at least 15 minutes (at room
temperature) when the ES400's main battery is removed. When the ES400 reaches a very low battery state, the
combination of main battery and backup battery retains RAM data in memory for at least 48 hours.

Charging Temperature

Charge batteries in temperatures from 0°C to 40°C (32°F to 104°F). Note that charging is intelligently controlled by
the ES400.
To accomplish this, for small periods of time, the ES400 alternately enables and disables battery charging to keep
the battery at acceptable temperatures. The ES400 indicates when charging is disabled due to abnormal
temperatures via its LED. See

Battery Status Indications

Battery icons appear on the status bar indicating the battery power level. When the main battery power falls below
a predetermined level the icon indicates the status and a battery dialog box appears indicating the status of the
battery.
