I took the dead battery out of my Compilot I; it has these specs:
I’m not a super accurate measurer…
MM 38.15X 23.5 x 3.75
IN 1.5 X .9 X .125
3.7V 450mAH 1.67Wh
Part Numbers: IP462539 lithium polymer
also this is on the battery: MH47577
I will likely order the battery that BoCat used…it doesn’t show an end connector…not sure how to work that out…maybe some soldering or splicing??
I got lucky and had a screwdriver bit that worked…2 screws and I got it out.
Costco wants $135 to send it off for a “refurb”…and I have to renew my membership according to the Costco person…so about $200.
I found a battery on Interstate Battery’s website with the same voltage/ mAh/Wh…same length and width…but too thick. I called them…no luck.
This is one hard to find battery!
Way off the subject…but…If I could have gotten closed captioning working on a “smart” TV, I wouldn’t have needed the Compilot. A lot of searches showed me that the TV will not do CC for Netflix movies…but a laptop will(maybe I could synchronize the movie with the laptop and do CC on the laptop?) , so will a ROKU $49, or an Amazon Fire TV stick…or other devices. All of these are cheaper than sending the Compilot back to Phonak through Costco. (But I’m trying BoCat’s battery solution.)
