Cameron Sino Battery for Sonos Controller CB100 CR100 3600mAh 3.7V

Direct Replacement for Sonos Controllers

This nickel-zinc battery replaces the original power pack in Sonos Controller CB100 and CR100 units. It matches the 3.70 volt rating and 3600 milliamp hour capacity specified for part numbers CP-CR100 and URC-CB100. The physical dimensions are 136.60 by 44.00 by 5.04 millimetres and the weight is 67.3 grams. Buyers who need a different voltage or a higher capacity will not find it here.

Steady Output Over a Full Day

The 13.3 watt-hour rating supports extended handheld use without the voltage sag seen in short-burst tests. A fully decoded chip communicates with the controller exactly as the factory cell does, so the battery gauge remains accurate throughout the discharge curve. After two or three complete charge and discharge cycles the pack reaches its rated capacity. Users who rely on rapid top-ups between rooms should note the chemistry favours full cycles.

Cool Running With Built-In Protection

Nickel-zinc chemistry runs at low internal resistance, so the pack stays near ambient temperature during normal playback control. Overcharge, over-discharge, over-voltage and short-circuit protection circuits are integrated into the battery assembly. No external charger is required; the controller manages charging through its original dock. Installers who ignore the connector alignment risk damaging the protection board.
