Normal battery charging should take about 2 hours to complete. Two sets of batteries can be charged at the same time in the USAlert WatchDog Pager Charger, one set in the pager itself and another set in the back of the Battery Charger. Battery life will obviously vary, depending heavily upon the activity of the pager. On fully recharged batteries, the WatchDog Pager should be able to operate in Selective Call Mode for 48 hours or 6 days at 8 hours/day. This is based on the industry standard of 5 thirty second calls per 8 hour day. Charged battery life will be reduced somewhat when in scanning or monitoring mode, depending upon the activity of the scanned or monitored channel(s).
The USAlert Rechargeable Batteries can be used interchangeably with both USAlert WatchDog and WatchDog LT Voice Pagers. Damaged batteries may produce unpredictable results and should be replaced.
