It carries a 2000mAh (80Wh) capacity and fits G-MAX 40V lawn mowers, chainsaws, trimmers, and leaf blowers. OEM part numbers covered include 29472, 24252, 29462, 29302, 20202, 22262, 25312, 29252, 29717, and 29727.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eG-MAX 40V platform compatibility:\u003c\/strong\u003e\n    All tools in the G-MAX 40V lineup share the same battery rail voltage, connector housing, and BMS handshake protocol — which is why a single pack slides into a mower, chainsaw, or blower without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through a G-MAX 40V mower and chainsaw under load. The BMS held stable across motor-start inrush spikes and correctly throttled discharge at the low-cell cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMotor inrush conditioning on first use:\u003c\/strong\u003e\n    Run the tool at half load for the first two cycles before full-throttle applications. This allows the BMS to profile the motor's inrush current draw before it sets its overcurrent protection thresholds — reducing nuisance trips on trigger pull.\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 G-MAX motor-start inrush surge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eEvery G-MAX 40V motor draws a short, sharp current spike the moment the trigger is pulled — especially chainsaws and mowers under blade load. If the BMS has not profiled that inrush pattern, it can read the spike as an overcurrent fault and cut the pack instantly. A pack coming out of storage is more vulnerable because cell impedance rises during inactivity, which amplifies the apparent inrush load. Running two light-load cycles recalibrates the BMS protection thresholds before you push the tool hard.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger blinking red and refusing to accept the pack after storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eGreenWorks 40V chargers have a minimum acceptance voltage — if a stored pack drops below roughly 25V, the charger's input circuit rejects it before a charge cycle can begin. This is a safety gate, not a dead battery. Place the pack in the charger and leave it connected for 10–15 minutes; most GreenWorks chargers include a recovery mode that trickle-feeds current until the cells reach acceptance voltage. If the light shifts from red to solid or flashing green, the recovery worked — let it complete a full charge before using the pack.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416010948698,"sku":"BWCS-GWP401PW-1","price":109.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416010981466,"sku":"BWCS-GWP401PW-2","price":128.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416011014234,"sku":"BWCS-GWP401PW-3","price":143.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GWP401PW-1.webp?v=1779759245","url":"https:\/\/batteryweb.com\/products\/greenworks-g-max-40v-replacement-battery-40v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
