9.2 Battery and Charging
Power is supplied by an internal rechargeable 6V lead-acid battery (4Ah). When “Lo.bAt” is displayed, the battery must
be recharged. Plug in the AC power adapter to recharge the battery. The scale may continue to be used on AC power
during charging. Full charging time is approximately 10-12 hours.
Battery life and recharge time will vary with use. Over time, the operating time per each full charge will degrade. If the
operating time is no longer acceptable, the battery must be replaced. When storing the scale for extended periods, the
battery must be charged every 90 days to avoid premature performance degradation.
