The USAlert Rechargeable Batteries for the WatchDog Pager are included with each WatchDog Pager as the primary power source, but as with any battery type, they eventually do wear out and have reduced performance over time. Battery life may be affected after 12 - 18 months of use, so it is recommended that the batteries be replaced at regular intervals to maintain optimum pager performance. The WatchDog Pager uses three “AAA” sized NiMH (Nickel Metal Hydride) rechargeable batteries, each rated at 1100 mA/hr. The NiMH rechargeable battery type is the preferred power source for small electronic devices that are used frequently and require high power. Replacement batteries are typically shipped in packs of three. Some alternate rechargeable batteries or batteries with a lower capacity rating have been found to create pager performance issues, so replacing your batteries with 1100 mA/hr capacity batteries is recommended.
The USAlert Rechargeable Batteries for the WatchDog LT Pager consist of three individual “AAA” NiMH (Nickel Metal Hydride) cells and come standard with each WatchDog LT Pager. A rechargeable NiMH battery type is preferred for small electronic devices that require strong power and are used frequently. Although the NiMH batteries are rechargeable, their useful life decreases gradually over time. Battery performance may be reduced after 12-18 months of use, so replacing the batteries at regular intervals is strongly recommended. The WatchDog LT Rechargeable Batteries are rated at 1100 mA/hr and are typically shipped in packs of three. Lower capacity batteries or batteries of lesser quality have been found to create performance issues in the WatchDog LT Pager. Replacing the Rechargeable Batteries with new batteries of the same 1100 mA/hr capacity ensures continued pager operation at peak efficiency.
The TPL Birdy 3G Rechargeable Battery is the standard power source for the Birdy 3G Pager. It is included in each Birdy 3G pager package along with the Pager, Desktop Charger with power adapter, belt clip and lanyard. Both the Desktop Charger and the alternative Desktop Charger with Antenna can be used to charge the battery.
The Rechargeable Battery Pack for the UniMax Alert and Ring Tone Amplifier is an optional backup power source, or the main power source if the UniMax Amplifier is to be used in a mobile situation. Consisting of three “AA” NiMH (Nickel Metal Hydride) rechargeable batteries, the Battery Pack takes approximately 10 hours to charge from a completely discharged condition to a fully charged state.
