It fits the WGC1000 and LS280 models used with LifeShield security and home automation systems. Voltage and capacity match the original spec exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWGC1000 and LS280 compatibility:\u003c\/strong\u003e\n    Both models use the same 3.7V single-cell Li-ion pack with identical connector pinout and BMS handshake. The shared form factor — 50.39 x 36.81 x 18.44mm — means the same cell seats correctly in either housing without modification.\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 the bench and confirmed the BMS holds the cutoff voltage correctly at both the low-cell and overcharge thresholds. IR LED output stayed consistent across the discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSingle-cell install note:\u003c\/strong\u003e\n    This remote runs on one Li-ion cell, not two alkalines. Confirm the polarity markings in the battery bay before seating the pack — the positive terminal orientation on Li-ion packs differs from what most users expect coming from alkaline replacements.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the WGC1000 remote stops responding even with a charged battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe LifeShield WGC1000 uses an IR LED that requires a stable voltage above roughly 3.5V to fire consistently. As a Li-ion cell ages and its internal resistance climbs, the voltage sags below that threshold under the brief high-current draw of each button press — even if a resting voltage check still reads 3.6V. The BMS may also trip a protection circuit if the cell has been deep-discharged below 2.5V at any point, locking output entirely. Replacing the cell resets both conditions.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRemote not working at all immediately after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is almost always a polarity reversal. Li-ion pack connectors on the WGC1000 and LS280 are easy to seat backwards — the housing doesn't physically prevent it. A reversed connection delivers no voltage to the control board, so the remote shows zero response. Pull the battery, check the positive and negative markings against the bay labels, reseat the pack in the correct orientation, and the remote should respond immediately.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416101879898,"sku":"BWCS-LS280RC-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416101912666,"sku":"BWCS-LS280RC-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416101945434,"sku":"BWCS-LS280RC-3","price":35.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LS280RC-1.webp?v=1779760264","url":"https:\/\/batteryweb.com\/products\/lifeshield-wgc1000-replacement-battery-37v-2800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
