APPENDIX D: NOTES ON RECHARAGEABLE BATTERY
D.1 OVERVIEW
Your scale contains two internal lead-acid rechargeable batteries connected in parallel.
Before using the scale for the first time, please charge the battery overnight.
The scale’s battery should operate for about 40 hours if left on continuously. Therefore,
greater usage times can be achieved by selecting an appropriate Auto Power Off Period
under
A15
of the User Menu.
The battery can be charged while ON or OFF and the scale can be operated while it’s
charging.
D.2 WHEN TO CHARGE THE INTERNAL BATTERY
1.
The best time to charge the sealed lead-acid type battery is any time the scale is not in
use. You do not have to wait for the Low Battery Indication – in fact it’s best you don’t.
Charging the battery when the scale is not in use keeps the battery “fresh” and is the
recommended way to manage your scale’s battery.
2.
When the battery needs to be charged, the Low Battery Indicator will appear in the
upper left-hand corner of the display. The scale may be used for an additional 15 to 30
minutes without damage to the internal battery.
If the scale is used for more than 30
minutes after a low battery indication, permanent damage may occur to the
battery and/or the battery may not accept a charge.
NOTE:
When a low battery indication occurs, the scale automatically shuts off after 5
minutes of idle use.
D.3 HOW TO CHARGE THE INTERNAL BATTERY
1. Connect the charger (AC Adapter 12 VDC, 800mA) to the scale, and then plug the
charger into an AC outlet.
Make sure that the AC voltage appearing at the wall
outlet matches the input voltage marked on the AC adapter.
2. After the charging period expires, unplug the charger from the AC outlet, then from the
scale. The scale is now ready for use under its own battery power.
NOTE:
The charger may be left connected to the scale indefinitely without damage to
the internal battery.
D.4 HOW LONG TO CHARGE THE INTERNAL BATTERY
In general, the battery should be allowed to charge a minimum of 1.5 hours for every hour
of use.
If you discharge the battery below 50% and do not allow the proper time for charging, you
may notice a decline in the usage period. This is due to the battery’s reluctance to accept a
charge.
