I’ve tried a bunch of brands and don’t find any to be significantly better than any others. Basically I just have to keep trying until I find ones that work in my devices. Once I find them they work for many many hours of training. It seems that they either work or they don’t…
Two changes that I’ve made that may or may not be helping:
- I shut off my computer in between rides. I think the devices were staying connected instead of sleeping which was prematurely killing the batteries. They last much longer now.
- I added a little shim of paper inside the battery compartment for my Stages to try to ensure that the batter is getting good contact. I had a feeling that they were slipping around inside. No idea if this is really true or not, but I’ve had better success with finding batteries that work since doing this.
