Headphones Sennheiser BA 2015
The BA 2015 rechargeable battery pack is a NiMH 1500 mAh, 2×1.2 V power source designed to replace two standard AA batteries in compatible bodypack transmitters and receivers. It supplies power to Sennheiser evolution wireless G3 Series 100, 300 and 500, 2000 Series, Tourguide SK 2020-D and EK 1039 devices and includes built-in monitoring to report charge status and manage safe charging.
Long operating times are provided by high-quality NiMH cells with a total capacity of 1500 mAh. Recharging is done via a convenient charging unit, and an integrated sensor indicates battery status, monitors temperature during recharging and prevents charging of non-rechargeable batteries.
Insert the BA 2015 battery pack into the device's battery compartment in place of two AA batteries, ensuring correct polarity and secure seating. Recharge the pack using the compatible Sennheiser charging unit according to the charger instructions. Do not attempt to charge the pack with chargers not designed for NiMH rechargeable packs.
Use the integrated sensor to monitor charge status and avoid charging non-rechargeable batteries. Charge in a suitable, well‑ventilated area and follow the charger manufacturer's guidelines to ensure safe temperature monitoring and optimal battery life.
