RECHARGEABLE LEAD-ACID BATTERY

Battery Charging

The scale can charge the battery (lead-acid rechargeable battery, 6v/4Ah). Just connect
the scale to the external power supply to charge it. The battery will be charged regardless if
the scale is on or off. It takes approximately 12 hours to charge the battery to full capacity
depending on the voltage of the battery. If the battery has been-discharged, a prolonged
charging time is required to bring the battery back to full capacity.

Low Battery

When the battery voltage falls below 5.7v, the low battery annunciator
The battery must be recharged. Continued use (approximately 15 minutes later), the
display will show Lo BAt in the weight field. If the battery voltage drops too low for
accurate weighing, the scale will automatically shut off and you will be unable to turn it
back on. When the low battery indicator is displayed, the operator should plug the power
supply into the scale and then into the proper electrical wall outlet. The scale will begin
charging the battery.

Notice

The battery should be recharged at least every 5 months regardless if it is used or not.
After a long storage, e.g. over 3 months, it is desired to cycle (charge/discharge) the
battery 3 times to let it restore to full capacity.
When replacing the battery, pay much attention to the poles. The positive (+) terminal must
be connected to the red connector and the negative (-) terminal must be connected to the
black connector. If connected wrongly, the battery will be damaged.
NOTE: The battery cover can be removed by loosening a single captive screw. This
screw remains attached to the cover which prevents it from falling out of the cover or
being dropped and lost.
The capacity of the batteries will reduce over the years and therefore also the total
operation time of the scale. This is not an error of the scale, but it is normal behavior or
rechargeable batteries.
