Sennheiser BA 2015

These batteries were not cheap however were purchased to simplify the arrangement in a local church making use of the L2015 docking charger. It is almost 2 years since they were installed and continue to deliver a consistent level of output even on the most demanding day (Sunday) where the transmitter can be out of the dock turned on for over 3 hours - although will be muted for periods within that time. They are also used frequently during the week at additional events. Charging time is good with transmitters being ready for an evening service after being on charge for about 5 hours. The charging dock is powered on permanently but the L2015 seems to manage charging well - I had worried that they would degrade quite rapidly if on permanent charge. I am perhaps only now seeing a slight drop on longevity on the most frequently used transmitter but there is plenty of life still in these.
