Sennheiser BA 2015 Rechargeable Battery Pack
The BA 2015 rechargeable battery pack powers transmitters and portable receivers of the wireless G2 Series and the 2015 FM system. It contains two rechargeable NiMH cells and is inserted into the battery compartment instead of two standard AA cells. The battery pack features an integrated sensor which indicates the battery status, monitors temperature during recharging and avoids the charging of non-rechargeable batteries.
