This is a genuine Dogtra replacement battery for the CS-SDR282SL collar receiver. It is a 3.7V lithium-polymer pack rated at 350mAh, sized 28.50 x 19.70 x 7.00 mm to drop into the collar's battery compartment. It suits owners reviving a collar whose pack no longer holds a charge, or keeping a training fleet running. The value is in the exact fit and genuine Dogtra cells rather than capacity: 350mAh is modest, so expect the same runtime as the original, not longer.
