The AdvanceRSM is powered by an internal rechargeable 1300 mAh lithium-ion battery which will keep the RSM totally independent of the phone battery. It provides approximately 30 days of standby time and over 8 hours of continuous talk time. It also features a multicolor LED charging status indicator and an advanced feature to show low-battery level.

The battery on the AdvanceRSM can be charged either via the USB socket or through standalone Single and 4 Bay chargers available by AdvanceTec. The drop-in chargers support home/office desktop (AC) or in-vehicle use (DC). The battery can be simply replaced when necessary with the removal of 1 screw.

The AdvanceRSM boasts a bold and rugged contemporary look designed to connect directly to the audio port of the phone. It comes with a 360 degree rotatable heavy duty clip to affix it to the lapel straps on shirts or jackets, as well as 3.5mm audio socket to support the use of a wired ear piece.
