It fits the Worx WG150s, WG152, WG250, and WG541 cordless string trimmers and edgers. Voltage and cell format match the original pack exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWG150s \/ WG152 \/ WG250 \/ WG541 platform fit:\u003c\/strong\u003e\n    These models share the same 18V battery rail, slide-in connector, and BMS handshake protocol — one pack covers the whole family without adapter hardware or firmware conflicts.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through simulated trimmer load profiles on the bench. The BMS handled motor-start inrush without tripping overcurrent and held voltage within spec across the discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eNi-MH break-in on first use:\u003c\/strong\u003e\n    Ni-MH cells need two to three full charge-discharge cycles before reaching rated capacity. Run the trimmer at a moderate load through a complete discharge each time — the cells will reach full 2000mAh output by cycle three.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger blinking red on WA3127 pack after storage\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH packs sitting unused for several months self-discharge below the charger's acceptance threshold — typically under 10V on an 18V pack. The charger reads this as a fault and blinks red instead of starting a charge cycle. Most Worx chargers include a recovery mode: hold the pack in the charger for 10–15 minutes and the unit will trickle-charge the cells up to acceptance voltage before switching to normal charge. If the charger does not recover the pack within 20 minutes, check terminal voltage directly — anything above 9V is recoverable with a compatible NiMH recovery charger.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTrimmer bogs or loses power mid-cut through thick grass\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSustained high load through dense grass forces the motor to draw continuous peak current, which heats both the motor housing and the battery cells simultaneously. Ni-MH cells have higher internal resistance than Li-ion, so voltage sag under load is more pronounced — particularly as the pack ages. The BMS will cut power if cell temperature exceeds its thermal threshold, causing the tool to stop mid-cut. Let the pack cool for five minutes, then check resting voltage: if it reads above 16V at rest, the cutoff was thermal, not a capacity failure — the pack will resume normally once cooled.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416030249050,"sku":"BWCS-WRX312PX-1","price":100.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416030281818,"sku":"BWCS-WRX312PX-2","price":117.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416030314586,"sku":"BWCS-WRX312PX-3","price":130.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-WRX312PX-1.webp?v=1779759627","url":"https:\/\/batteryweb.com\/products\/worx-wg150s-replacement-battery-18v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
