Li-ion polymer batteries are lightweight, store more energy, and charge easily.
Battery lifespan
One charge cycle equals one full discharge and one full recharge. The Li-ion polymer battery is designed to handle approximately 800 cycles before its capacity drops significantly.
How charging works
The battery charges automatically when you place the device in the transmitter's charging compartment. This battery is not user-replaceable. If the running time becomes noticeably shorter, contact Sennheiser service for a battery replacement.
Optional MCA 800 charging adapter
If you have the MCA 800 charger, you can use it to charge the stethoset receiver and extend its operating time. The device can also be used while charging.
