It fits the Worx WG180, WG280, WG380, and WG580 cordless trimmer and edger series. Slot it into any compatible charger and tool — the connector and BMS handshake match the original pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWG180 \/ WG280 \/ WG380 \/ WG580 platform fit:\u003c\/strong\u003e\n    All four models share the same 40V battery rail, slide-latch connector, and BMS communication protocol. One pack works across the entire lineup without adapters or firmware differences.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through repeated motor-start inrush events on a WG180 trimmer. The BMS held the overcurrent threshold correctly and did not trip during normal trigger pulls at full load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use load conditioning on trimmer motors:\u003c\/strong\u003e\n    Run the trimmer at half throttle for the first two full discharge cycles before sustained full-speed cutting. This lets the BMS profile the motor's inrush current draw and set overcurrent protection thresholds accurately before you push it into dense grass or thick growth.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff on trigger pull during dense vegetation cutting\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the trimmer head bites into thick grass or weeds, the motor draws a sharp inrush spike before it reaches operating speed. On a new or storage-depleted pack, the BMS may read that spike as an overcurrent fault and cut power instantly. The fix is gradual load conditioning — two cycles at partial throttle recalibrates the BMS trip threshold to the actual motor profile. After conditioning, full-throttle cuts into dense growth should not trigger a cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger shows blinking red and won't begin charging after storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion packs stored uncharged for more than a few months can drop below the charger's acceptance voltage floor — typically around 30V on a 40V system. The charger detects a cell voltage it considers unsafe and refuses to start the charge cycle, showing a blinking red fault light. Remove the pack, wait 60 seconds, and reinsert it to trigger a fresh handshake. If the charger still rejects the pack, check cell voltage at the terminals — anything above 28V should respond to a trickle-mode charger or a second reinsertion attempt.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416009375834,"sku":"BWCS-WRK180PW-1","price":90.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416009408602,"sku":"BWCS-WRK180PW-2","price":106.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416009441370,"sku":"BWCS-WRK180PW-3","price":117.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-WRK180PW-1.webp?v=1779759304","url":"https:\/\/batteryweb.com\/products\/worx-wg180-replacement-battery-40v-1500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
