It fits the GreenWorks Pro 80V platform, covering mowers, blowers, and string trimmers including the GCS80420, GBL80320, and GLM801600 among 56 additional compatible models. Voltage and connector match the OEM pack — the BMS handshake is compatible with GreenWorks Pro 80V chargers.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePro 80V platform fit:\u003c\/strong\u003e\n    All models in the GreenWorks Pro 80V line share the same 80V rail, battery connector, and BMS communication protocol. One battery moves between mower, blower, and trimmer without adapter or modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack on a GCS80420 deck motor through simulated blade-load cycles. The BMS held stable under inrush current at startup and throttled correctly when cell temperature approached the thermal threshold — no nuisance trips on clean dry grass loads.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSeasonal storage tip:\u003c\/strong\u003e\n    Before the first spring mow, bring the battery indoors overnight if garage temperatures are below 10°C. Cold Li-ion cells have elevated internal resistance, and the blade motor's inrush current can trip the BMS on a pack that hasn't warmed to room temperature.\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 and wet-grass blade load\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Pro 80V blade motor draws significantly higher inrush current when cutting dense or wet grass compared to dry conditions. If the BMS detects that current draw exceeds its threshold — typically caused by a clogged deck or overgrown patch — it cuts output to protect the cells. This is not a battery fault; it's the protection circuit doing its job. Clear the deck, allow a 60-second reset, then restart the mower at a slower walking pace through the heavy section.\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 over months of storage. If the pack voltage drops below the charger's acceptance threshold — typically around 2.5V per cell — the charger refuses to enter normal charge mode and shows a fault or red indicator. Some GreenWorks Pro 80V chargers include a recovery mode: insert the pack, wait up to 30 minutes, and the charger will attempt a low-current pre-charge to bring cells back above the acceptance floor. If the fault light clears and charging begins, the pack is recovering normally. If it does not clear after 30 minutes, cell voltage has dropped too far for recovery.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381303803994,"sku":"BWCS-GWP800PW-1","price":68.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381303836762,"sku":"BWCS-GWP800PW-2","price":80.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381303869530,"sku":"BWCS-GWP800PW-3","price":88.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GWP800PW-1.webp?v=1778899964","url":"https:\/\/batteryweb.com\/products\/greenworks-pro-80v-replacement-battery-80v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
