Normal recharging should take about 2 hours to complete, 3-4 hours if the batteries are recharging from a fully discharged state. Once fully recharged, the WatchDog LT Pager should be able to operate in Selective Call mode (or Standby mode) for 48 hours or 6 days at 8 hours per day, based on the industry standard of 5 thirty second calls per 8 hour day. Battery life will obviously vary with operational use. Monitoring or scanning channels uses more battery power, the amount of power depending heavily on the activity of the monitored or scanned channel(s).
The Rechargeable Batteries for the WatchDog LT Pager are the primary power source for both the WatchDog LT and WatchDog Pagers and are interchangeable. Damaged batteries may produce unpredictable results and should be replaced.
