Take care to insert the Radio Pack batteries with the contacts facing down into the Radio Pack and oriented such that the contacts on the battery will line-up with the contacts inside the Radio Pack battery compartment. See Install Radio Pack Batteries for more on this procedure.
The PBT-LIP-01 battery can be charged either inside the Radio Pack with the provided RP Wall Charger, with the provided USB Cable, or with the Pliant 6+6 Drop-In Radio Pack and Battery Charger (PBT-RPC-66).
Using the RP Wall Charger
To charge the Radio Pack (RP), connect the plug-in battery charger (included with the RP) to a standard wall outlet and to the Micro-USB connector on the RP. The connector is located under the rubberized access cover on the side of the RP. The battery requires approximately 3 hours to charge from empty.
Using the USB Cable
The Radio Pack (RP) may also be charged by connecting the USB-A-to-Micro-B pairing cable to the USB port of a PC and to the Micro-USB connector on the RP. The connector is located under the rubberized access cover on the side of a standard-sized RP and on the bottom of a compact-sized RP. The battery requires approximately 3 hours to charge from empty.
Using the 6+6 Drop-In Radio Pack and Battery Charger
The Pliant 6+6 Drop-in Radio Pack and Battery Charger charges up to six batteries in the Radio Pack and up to six stand-alone batteries simultaneously. An optional 3-position mounting bracket is available for flexible, secure charger positioning [PAC-PBT-MNT]. Batteries inside Radio Packs require approximately 4 hours to charge from empty; batteries alone require approximately 2.5 hours to charge from empty.
6+6 Drop-In RP and Battery Charger
CAUTION: The operating temperature for battery charging with the PBT-RPC-66 Drop-In Charger is 0°C to 45°C (32° F to 113° F). If charger(s) overheat, they need to be moved to a cooler area to charge batteries properly. As a lithium-polymer battery safety mechanism, the battery chargers include a safety circuit, which prevents charging of batteries if the ambient temperature is too hot.
