It slots into the same battery bay and communicates with the mower's onboard BMS using the same handshake protocol as the original pack. When your original battery no longer holds charge or cuts out under load, this is the direct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePR275Ci and PR280Li platform fit:\u003c\/strong\u003e\n    These models share a common 58V battery rail, connector format, and BMS communication protocol. The same pack works across the lineup because PoulanPro standardised the battery interface across this voltage class — swapping between supported models requires no adapters or configuration changes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through full load cycles simulating blade motor inrush under thick-grass conditions. The BMS handled the high-current draw without false tripping, and cell voltage held stable across the discharge curve without unexpected sag at the low end.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSeasonal storage prep:\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 have higher internal resistance, and the blade motor's inrush current can trip the BMS on a cold pack before the mower even starts cutting.\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 PR275Ci blade motor draws a sharp inrush of current each time it bites into dense or wet grass. If the battery's BMS detects that draw exceeding its threshold — usually caused by a degraded original pack with elevated internal resistance — it cuts power to protect the cells. A new pack with lower internal resistance handles those inrush spikes more cleanly. If cutouts continue with the new battery, the issue is likely a partially blocked deck or a dull blade forcing the motor to work harder.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger showing a fault light after the mower sat all winter\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells that discharge below roughly 2.5V per cell during long storage fall outside the charger's acceptance window — the charger reads the pack as faulty and refuses to charge. This is common after a full winter in an unheated garage. Some chargers have a recovery or trickle mode; check your charger manual for that sequence. If the original pack won't recover, this replacement battery ships at a partial state of charge that keeps cells above the recovery threshold from day one.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381291679834,"sku":"BWCS-HRA581VX-1","price":217.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381291712602,"sku":"BWCS-HRA581VX-2","price":258.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381291745370,"sku":"BWCS-HRA581VX-3","price":288.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HRA581VX-1.webp?v=1778899901","url":"https:\/\/batteryweb.com\/products\/poulanpro-pr275ci-replacement-battery-58v-5000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
