It fits the TSS Keypad, Lynx Plus, L5000 Panel, and 8DLLKP500 among others, all of which share the same 300-06868 cell format. Voltage and capacity match the OEM spec exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMulti-model fit across the Lynx and L5000 platform:\u003c\/strong\u003e\n    These panels and keypads share the same battery compartment geometry, connector type, and 7.2V Ni-MH charge circuit. A single cell spec covers the full group because the charge management on each unit expects the same voltage curve and internal resistance range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on an L5000 panel and confirmed the BMS accepted the charge cycle without tripping a fault. Voltage under float settled correctly, and the panel cleared its low-battery flag after the conditioning window.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation conditioning on Honeywell keypads:\u003c\/strong\u003e\n    Do not run a zone or diagnostic test immediately after fitting this cell. The panel's charge circuit needs 24–48 hours of float charge before the battery monitor reports accurately. Testing before that window will likely trigger a false low-battery alert.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAlarm panel showing low battery hours after installing a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is normal behaviour on Honeywell Lynx and L5000 hardware. The panel's battery monitor checks voltage against a threshold, but a freshly installed Ni-MH cell hasn't reached full float charge yet. The cell may read 6.8–7.0V on installation, which sits below the panel's pass threshold of approximately 7.2V. Leave the system powered and connected for 24–48 hours — the fault flag will clear once the cell reaches full charge.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAlarm losing programmed zones after a mains power cut\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the panel drops its zone programming during a power outage after a battery swap, the new cell hadn't been accepted by the backup circuit yet. Honeywell panels require the backup battery to complete a conditioning cycle before it can hold the panel's memory under load. A cell swapped hours before a power cut may not yet supply stable voltage when mains drops. Restore mains power, allow a full 48-hour conditioning period, then confirm the backup circuit is active before the next outage.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43309833158746,"sku":"BWCS-HYL500BT-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43309833191514,"sku":"BWCS-HYL500BT-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43309833224282,"sku":"BWCS-HYL500BT-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HYL500BT-1.webp?v=1777868260","url":"https:\/\/batteryweb.com\/products\/honeywell-tss-keypad-replacement-battery-72v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
