It replaces OEM part numbers DEM-1274 and DEM-1280. When the original cell degrades, the remote loses the ability to arm or disarm the Magellan system reliably — this cell restores that function.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eK32RF and PAR-120 compatibility:\u003c\/strong\u003e\n    Both remotes share the same 3.7V single-cell Li-ion architecture, the same physical footprint (53.00 × 33.90 × 5.70mm), and the same OEM connector and BMS handshake — which is why one cell covers both platforms.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on a PAR-120 transmitter. The BMS accepted the cell without fault flags, and the remote re-paired with the panel without clearing existing zone programming.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFloat charge before first activation:\u003c\/strong\u003e\n    After fitting this cell, place the remote on charge for a full cycle before arming or disarming. The panel receiver reads signal strength against battery voltage — a partially charged new cell can cause the panel to log a low-battery event on first use, even though the cell is fine.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Magellan panel reports low battery 24 hours after a new cell is fitted\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Magellan panel polls the remote transmitter for a voltage status signal on a timed cycle. A new Li-ion cell ships at a storage charge — typically around 3.5V — not at full float voltage (4.2V). If the panel polls within the first charge cycle, it sees sub-threshold voltage and logs a low-battery event. This is not a faulty cell. Allow the remote to complete a full charge to 4.2V before the panel runs its next poll, and the fault clears automatically.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRemote transmits but panel does not respond after cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis usually means the remote lost its pairing state when power was interrupted during the cell swap. The K32RF and PAR-120 store pairing data in volatile memory, which can reset if the old cell was fully depleted before removal. Re-enter the panel's receiver programming menu and re-enrol the remote using the original user code. Once the panel confirms enrolment, test arm and disarm — the remote should respond within one transmission cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43309816643674,"sku":"BWCS-DMR120BT-1","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43309816676442,"sku":"BWCS-DMR120BT-2","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43309816709210,"sku":"BWCS-DMR120BT-3","price":51.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DMR120BT-1.webp?v=1777868106","url":"https:\/\/batteryweb.com\/products\/magellan-k32rf-replacement-battery-37v-1200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
