APPENDIX D: NOTES ON OPTIONAL BATTERY

D.1 OVERVIEW

Your scale contains an internal lead-acid rechargeable battery. Before using the scale for the first

time, please charge the battery overnight.
The scale’s battery should operate for about 10 hours if left on continuously. Therefore, greater

usage times can be achieved by selecting an appropriate Auto Power Off Period under

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

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.

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.
