IMC CAMOS BHS-600 intercom battery replacement
Just posted this in the "Accessories/Intercom" forum, but thought someone might find it useful here...
So I've had my IMC CAMOS BHS-600 intercom for a couple years and hundreds of battery cycles and the battery is now kicking the buxket. It will ast a day, but the standby time is dying off to where I need to charge it everyday, which is unusual. I spent the day researching whether to get the newer BTS-200/300 series, or something else for another $200, just because the boneheads designed it with a battery that isn't user replaceable.
THe 600 has worked flawlessly with my iphone, Zumo 550 and a wirevo D1000 on my sirius radio for a long time, so after almost chunking down another $200, I decided to crack the case. We ARE talking a battery here...
The case has two screws on the back, and then the typical small, plastic "tab A fits into slot B" deals that if one is careful, can be seperated without breaking, then the halves split apart. Inside, the circuit board is held in by a micro-screw and the battery is under the circuit board.
The battery is a 3.7 volt "553045P" lithium ion battery pack soldered into the underside of the circuit board. It is stuck to the back of the circuit board with some kind of adhesive which can be removed carefully. The leads where it is soldered are just long enough to splice in a new one.
I've Googled and found reference to "553045P" batteries but not yet found an actual source yet (any help is appreciated). It's specs are 2.7 volts, 650 mah, 620 mah minimum, 60 g resistance(?) and is 5mm x 29.5mm x 44 mm
I'd love to raise the mah rating but the dimensions are really tight. I have thought of making some kind of external pack, but, whatever... A new battery should be fine.
