Sennheiser XSW wireless - Programmed obsolescence?
I love my wireless Sennheiser XSW pedalboard system but have noticed lately that I needed to recharge the transmitters more and more often, which is a drag even when you have spares. I feared I'd have to buy new transmitters but searched the web and found this very instructive post on a photographers' forum.

The factory battery is a 850 mAh but I got myself some 1500 mAh batteries just to check if I can play longer before having to recharge.
Stay tuned. I'll give you the result of this experiment in a few days.
