It fits the GCS80420 chainsaw, GBL80320 blower, GLM801600 lawn mower, and 56 additional Pro 80V tools sharing the same battery bay. Voltage and connector match the original GreenWorks 80V pack specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePro 80V platform compatibility:\u003c\/strong\u003e\n    All listed models run the same 80V voltage rail and use the same slide-in battery interface with a common BMS handshake signal. One battery services the full tool fleet without any adapters.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack on a Pro 80V mower deck under simulated blade load. The BMS held through normal motor inrush, stepped current limiting correctly under sustained draw, and the charger accepted the pack through a full charge cycle without fault codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSeasonal storage tip:\u003c\/strong\u003e\n    Before the first mow of spring, bring the battery indoors overnight if temperatures are below 10°C. Cold Li-ion cells have higher internal resistance, and the blade motor inrush current on a cold pack can trip the BMS before the mower takes a single pass.\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 thick-grass or wet-grass blade load\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Pro 80V BMS monitors cell current in real time. When the blade motor hits dense or wet grass, inrush current spikes sharply and can cross the BMS overcurrent threshold within milliseconds. The pack shuts down as a protective response — not a battery fault. Clearing thicker sections in two passes instead of one keeps the current draw below the trip point and prevents mid-run cutoffs.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger showing fault light after mower sat in garage all winter\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge slowly during storage. After several months in a cold garage, cell voltage can drop below the minimum acceptance threshold the charger checks before it begins a charge cycle. The charger reads this as a fault rather than a depleted pack. Place the battery in a room-temperature environment for two hours, then reconnect to the charger — most packs recover and the charger clears to green once cell temperature and open-circuit voltage return above 60V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381304033370,"sku":"BWCS-GWP800PX-1","price":150.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381304066138,"sku":"BWCS-GWP800PX-2","price":178.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381304098906,"sku":"BWCS-GWP800PX-3","price":199.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GWP800PX-1.webp?v=1778899964","url":"https:\/\/batteryweb.com\/products\/greenworks-pro-80v-replacement-battery-80v-4000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
