It matches the OEM voltage rail, connector, and BMS handshake required by these models. Capacity is 27Wh — the same as the stock unit it replaces.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eR-series mower compatibility:\u003c\/strong\u003e\n    The R38Li, R50Li, R75Li, and 124562 all share the same 18V battery bay, connector pinout, and BMS communication protocol. This pack communicates correctly with the mower's charge controller — no fault codes on insertion.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through full charge and discharge cycles on an R50Li mower platform. The BMS responded correctly to motor-start inrush, held voltage above the low-cell cutoff threshold, and accepted a full recharge without fault flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst spring use — cold-cell precaution:\u003c\/strong\u003e\n    If your mower has been stored through winter, bring the battery indoors overnight before the first cut. Below 10°C, Li-ion internal resistance rises sharply and the blade motor's inrush current can trip the BMS on a cold pack — leaving the mower dead at the start of the row.\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 R-series blade motor draws significantly more current through dense or damp grass than on a dry, short lawn. If the pack's BMS detects that current has spiked beyond the safe cell discharge threshold, it cuts power to protect the cells. This shows up as a sudden stop mid-row with no warning light. Let the mower sit for two to three minutes — the BMS will reset once current demand drops to zero — then resume on a lighter grass pass.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger refusing to accept the pack after winter storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge slowly in storage. A pack left in a cold garage from autumn to spring can drop below the charger's minimum acceptance voltage — typically around 12V for an 18V pack — and the charger will show a fault or simply do nothing. Place the battery in a warm room (18–22°C) for several hours before trying the charger again. If the charger still won't engage, check cell voltage with a multimeter at the pack terminals; anything above 10V should recover with a brief trickle charge or a compatible recovery-mode charger.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381319204954,"sku":"BWCS-GRA700PW-1","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381319237722,"sku":"BWCS-GRA700PW-2","price":55.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381319270490,"sku":"BWCS-GRA700PW-3","price":61.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GRA700PW-1.webp?v=1778899963","url":"https:\/\/batteryweb.com\/products\/gardena-124562-replacement-battery-18v-1500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
