It also fits the HT24i and SN280Li platforms that share the same 58V battery rail and connector housing. OEM part numbers covered include PR140Li, PR280Li, and 590923804.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePR275Ci \/ PR280Li platform fit:\u003c\/strong\u003e\n    These models share a common 58V bus, identical connector keying, and the same BMS handshake protocol — the battery seats and communicates with the deck controller without modification.\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 PR275Ci deck. The BMS held steady through repeated high-draw motor starts and transitioned cleanly into steady-state cutting current without tripping.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-season cold storage tip:\u003c\/strong\u003e\n    Before the first spring mow, 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 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 PR275Ci blade motor draws significantly more current through dense or wet grass than on a dry, maintained lawn. When that load spike exceeds the BMS overcurrent threshold, the pack shuts down mid-row as a protection response. This isn't a battery fault — it's the BMS doing its job. Slow the mowing pace in heavy sections to reduce inrush demand and keep the pack below the cutoff trigger.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger showing fault light after mower sat unused all winter\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge slowly over months of storage. If the pack drops below approximately 2.5V per cell over winter, most chargers read it as a fault and refuse to begin a charge cycle. The fix is a slow-recovery charge — if your charger has a recovery or wake mode, use it. If not, some packs will recover after being connected and disconnected from the charger several times, allowing cell voltage to creep above the acceptance threshold before a full charge cycle begins.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381292138586,"sku":"BWCS-HRA580VX-1","price":183.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381292171354,"sku":"BWCS-HRA580VX-2","price":218.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381292204122,"sku":"BWCS-HRA580VX-3","price":243.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HRA580VX_1.webp?v=1778899901","url":"https:\/\/batteryweb.com\/products\/poulanpro-pr275ci-replacement-battery-58v-3000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
