Looking for replacement battery for Logitech MM50 S-0173A Speakers?
I have a Logitech MM50 S-0173A speaker dock. Anyone have any clues as to where I can find a replacement battery for these iPod speakers from Logitec? I've tried Logitech - their answer is "we no longer make this device" - not a great deal of help!!. The battery is about 1/2" dia x 2" lithium, 3.7 volts.
here is the replacement battery for Logitech MM50
Like EKWF said (#comment229709), a Logitech mm50 battery contains a single 18650 cell. Its battery cell is soldered to a protection circuitboard, and surrounded by insulator skin (heat shrink tube). Its battery protection board connects to mainboard through three wires: black (battery negative), red (battery positive), and white (NTC thermistor between black and white, if I recall correctly, but check yours to be sure). As simply one cell comprises its battery, it can be re-celled fairly easily. This battery is discussed in some detail, with pictures, on iLounge. (Topic: Logitech mm50 & Pure Fi anywhere batteries)
