I have had two motion sensors in my system since June 2017. One in a high traffic area and one in a low traffic area. System works great (after some early OOMA software updates). The motion sensor in the high traffic area is till working with the original battery supplied by OOMA, now over sixteen months. The original battery in the low traffic are lasted about 13 months. When that battery failed, I replaced it with a Duracell CR123 that lasted about three weeks. I replaced again twice with Energizer CR123 batteries that also lasted about three weeks each. Now on my third Energizer out of a pack of six. The new batteries show 100% with a a pulse load battery tester and the old ones show zero percent. I never get a low battery indication, just a sensor disconnect which is only corrected with a new battery.
Anyone have a battery brand recommendation? Where can I buy the exact brands that OOMA includes with their product.
