It fits via OEM part numbers WA3038, EP3630, EP3620, and EP3640. The battery slots into the same bay as the original and communicates with the mower's onboard BMS using the same protocol.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEG361.9, EG560.9, and ENVIRO Brushless 60V platform:\u003c\/strong\u003e\n    These models share a common 60V battery architecture, connector pinout, and BMS handshake. One replacement covers the full platform without adapter modifications.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through blade-start inrush cycles on a 60V mower deck. The BMS held cutoff thresholds within spec across repeated high-load starts, and cell balancing engaged correctly after full charge cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSeasonal storage tip:\u003c\/strong\u003e\n    Before first use of the season, bring the battery indoors overnight if temperatures are below 10°C. Cold Li-ion cells carry higher internal resistance, and the blade motor's inrush current can trip the BMS on a cold pack before the mower even completes one 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 and wet-grass blade loads\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the mower deck hits dense or wet grass, the blade motor pulls a surge current well above its steady-state draw. If that surge exceeds the BMS overcurrent threshold — typically triggered in under 200 milliseconds — the pack shuts off as a protection response, not a fault. This is especially common with a new pack on its first few cycles before cells reach full conditioned capacity. Mowing at a slower forward pace through heavy sections reduces peak current draw and keeps the BMS from tripping. After conditioning across five full charge-discharge cycles, the cells handle inrush more consistently.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMower cuts out mid-row and then restarts after a short wait\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is thermal protection activating, not a battery fault. The pack's internal temperature sensor cuts power when cell temperature exceeds the safe operating ceiling — common after extended mowing in warm conditions or back-to-back passes without pause. The mower will restart once the pack cools below the reset threshold. Allow at least a 5-minute rest with the battery removed from direct sunlight, then reinsert and resume. If cutouts recur within a single session at short intervals, check that the battery vents are not blocked by grass clippings.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381286142042,"sku":"BWCS-WEG361PX-1","price":211.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381286174810,"sku":"BWCS-WEG361PX-2","price":251.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381286207578,"sku":"BWCS-WEG361PX-3","price":281.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-WEG361PX-1.webp?v=1778899919","url":"https:\/\/batteryweb.com\/products\/worx-enviro-eg3619-60v-replacement-battery-60v-5000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
