It slots into the same bay and connects to the same BMS handshake the charger expects. Voltage and cell count match the factory specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e124563 platform fit:\u003c\/strong\u003e\n    The 124563 mower runs a 25.2V (6S Li-ion) architecture. This pack matches that cell count and voltage rail, so the onboard BMS and charger communicate the same way they did with the original battery.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through full charge and simulated blade-load discharge. The BMS held protection thresholds at both the high-current inrush phase and the sustained draw phase without tripping or dropping the pack into fault mode.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSeasonal storage tip:\u003c\/strong\u003e\n    If the mower has sat unused since last season, bring the battery indoors overnight before the first use. Below 10°C, Li-ion cells develop higher internal resistance. The blade motor's inrush current on startup can trip the BMS on a cold pack — warming it first prevents a false fault cutoff.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff under thick grass or wet-grass blade load\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe 124563's blade motor pulls significantly more current through dense or wet grass than on a normal dry lawn. If that inrush spike exceeds the BMS overcurrent threshold, the pack cuts out mid-row as a protection response — not a battery fault. Let the mower sit for 30 seconds, then restart. To reduce trips, overlap rows less and mow wet grass at a slightly slower walking pace, which keeps sustained current draw below the BMS ceiling.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger not accepting the pack after winter storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge slowly in storage. If the 124563's battery sat in a cold garage all winter, individual cells may have dropped below the charger's minimum acceptance voltage — typically around 2.5V per cell. The charger reads the pack as too low to accept and shows a fault light. Some chargers have a recovery or trickle mode; plug in and wait 10–15 minutes before the charger steps up to full charge current. If the pack reaches 25.2V during that window, the charge cycle will complete normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381314715738,"sku":"BWCS-ABL100VX-1","price":191.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381314748506,"sku":"BWCS-ABL100VX-2","price":226.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381314781274,"sku":"BWCS-ABL100VX-3","price":253.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ABL100VX-1.webp?v=1778899944","url":"https:\/\/batteryweb.com\/products\/alpina-124563-replacement-battery-252v-6900mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
