It matches OEM part numbers 1126-9105-01, 1126-9138-01, and 1126-9174-01. Voltage, connector, and BMS communication all match the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCross-model fit — 325 through 522:\u003c\/strong\u003e\n    These Stiga mower models share the same 25.2V battery platform, connector housing, and BMS handshake protocol. One pack fits across the range 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 and sustained cutting loads. The BMS held steady across multiple high-draw events and entered thermal protection only at the expected threshold — no nuisance trips on normal turf.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSeasonal storage tip:\u003c\/strong\u003e\n    Before packing the mower away at end of season, charge this battery to around 50–60% rather than full. Stiga Li-ion packs stored at full charge over winter experience faster cell degradation — partial charge lowers cell stress during long-term storage.\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\"\u003eWhen the blade hits dense or wet grass, the motor draws a sharp inrush of current — significantly higher than normal cutting load. If that spike exceeds the BMS current threshold, the pack cuts power immediately to protect the cells. This is not a fault with the battery; it is the protection circuit doing its job. Reduce deck height by one setting in thick sections, or make a second pass rather than cutting more than one-third of the blade length in a single run.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger shows fault light after mower sat all winter\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells that self-discharge below roughly 2.5V per cell over a long storage period will be rejected by the standard charger — the BMS sees the pack as outside the safe acceptance window and refuses to initiate a charge cycle. This shows up as a solid fault light or no response from the charger LED. To recover the pack, place it in a warm room (above 15°C) for two hours, then reconnect the charger. If the charger still shows a fault after 30 minutes on charge, check cell voltage with a multimeter — a pack resting below 18V total will need a compatible recovery charger capable of a low-current pre-charge below 2.8V per cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381315862618,"sku":"BWCS-ABL110VX-1","price":223.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381315895386,"sku":"BWCS-ABL110VX-2","price":266.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381315928154,"sku":"BWCS-ABL110VX-3","price":297.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ABL110VX-1.webp?v=1778899944","url":"https:\/\/batteryweb.com\/products\/stiga-325-replacement-battery-252v-9000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
