It fits PetSafe wireless containment and training collar receivers, including PBC00-10782, PBC00-11047, PBC00-12725, PBC00-12726, and 19 additional compatible models. When the original cell depletes, the collar stops responding to the fence or training signal entirely.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCross-model fit on PetSafe collar receivers:\u003c\/strong\u003e\n    These collar models share the same RFA-188 cell housing, contact orientation, and 3V operating threshold. The receiver circuit draws from a single cell with no parallel configuration, so voltage at replacement must match exactly — Li-MnO2 holds a flat 3V discharge curve that alkaline alternatives cannot replicate.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell in a PBC00-10782 receiver and confirmed the collar powered on cleanly, the BMS accepted the cell without fault, and the static correction signal fired at the correct threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst signal acquisition after swap:\u003c\/strong\u003e\n    After installing this cell in a containment collar, walk the dog to the boundary zone and allow the receiver to re-register with the transmitter before assuming the system is live — some PetSafe base stations require the collar to cycle through the boundary field once to re-sync correction levels.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the collar gives no correction at the boundary after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-MnO2 cells ship with a thin passivation layer on the lithium anode that forms during storage. On first load, this layer causes a brief voltage dip — sometimes enough to drop below the collar receiver's operating threshold. The fix is simple: install the cell, press the test button on the collar to force an initial load, and the passivation clears within a few seconds. After that, the cell delivers a stable 3V and the receiver responds normally at the boundary.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCollar indicator light flashes but correction still not firing\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA flashing indicator confirms the receiver has power and is detecting the boundary signal, but the correction prongs not firing usually points to contact corrosion or a cell seated slightly off-axis in the compartment. Remove the cell, clean the contacts with a dry cloth, and check that the cell sits flush with both terminals under light pressure. Measure voltage at the cell terminals directly — anything below 2.8V means the cell is already depleted and needs replacement.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360149536858,"sku":"BWCS-PRF880SL-1","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360149569626,"sku":"BWCS-PRF880SL-2","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360149602394,"sku":"BWCS-PRF880SL-3","price":34.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PRF880SL-1.webp?v=1778610901","url":"https:\/\/batteryweb.com\/products\/petsafe-pbc00-10782-replacement-battery-3v-150mah-li-mno2","provider":"BatteryWeb","version":"1.0","type":"link"}
