The K32RF is a wireless security keypad used in home and commercial alarm systems to send arm and disarm commands to the control panel. When the original cell depletes, the keypad loses the ability to communicate with the panel until the battery is replaced.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eK32RF wireless keypad fit:\u003c\/strong\u003e\n    The K32RF operates on a 3.7V Li-ion cell to power its RF transmitter, LED display, and onboard processor simultaneously. This replacement matches the original voltage rail and physical dimensions (53.00 × 33.90 × 5.70mm) required to seat correctly inside the keypad housing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles and confirmed the protection circuit trips correctly on over-discharge. The BMS held a stable voltage throughout normal keypad transmit cycles without voltage sag dropping below the panel's communication threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation charge window:\u003c\/strong\u003e\n    Do not run a zone or tamper test immediately after fitting this cell. Allow 24 to 48 hours on float charge before triggering any diagnostic test — the panel needs this window to accept the new battery and stop flagging a low-battery condition.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAlarm panel reporting low battery hours after fitting a new K32RF cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a float charge acceptance issue, not a fault with the replacement cell. The alarm panel's battery monitoring circuit samples voltage against a threshold and will continue reporting low battery until the new cell reaches a full float charge state. That process takes 24 to 48 hours of uninterrupted charge time connected to the panel. Pulling the keypad off the charger or running a test cycle before that window closes resets the counter and extends the wait.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eK32RF keypad showing tamper fault immediately after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA tamper fault appearing right after a battery replacement almost always means the keypad cover or backplate is not fully seated. The K32RF has a tamper switch that triggers if the housing is not completely closed and latched after the battery access point is reassembled. Open the keypad, reseat the cover, and press firmly until all clips engage. Once the housing is fully closed, the tamper fault should clear within one to two minutes without any panel reset required.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43309816545370,"sku":"BWCS-DMR120BT-1","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43309816578138,"sku":"BWCS-DMR120BT-2","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43309816610906,"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\/paradox-k32rf-wireless-led-kyepad-replacement-battery-37v-1200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
