Capacity is 6900mAh (173.88Wh), matching the OEM specification. It connects via the same locking slide rail and talks to the mower's BMS using the original communication protocol.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e325 and 328S platform fit:\u003c\/strong\u003e\n    These models share a common 25.2V battery architecture, the same physical rail connector, and the same BMS handshake signal. One pack covers the full group — no adapters or firmware changes needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through full discharge cycles on a 325 deck assembly, monitoring cell voltage and BMS response under simulated blade load. The protection circuit held cutoff at the correct threshold with no false trips on flat terrain.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSpring start-up tip:\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 carry higher internal resistance, and the blade motor's inrush current on startup can trip the BMS before the cells have warmed to operating 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 325's blade motor draws a sharp inrush current whenever it bites into dense or wet grass. If the battery's state of charge is already below 30%, this spike can push instantaneous current past the BMS cutoff threshold, and the mower stops mid-row. The pack is not faulty — the protection circuit is doing its job. Keep charge above 40% before tackling heavy sections and mow wet grass in a higher cut setting to reduce motor load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger showing a fault light after the mower sat unused all winter\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge at roughly 2–3% per month. After six months in an unheated garage, cell voltage can drop below the charger's acceptance threshold — typically 2.5V per cell — and the charger refuses to start a charge cycle. Place the battery in a warm room (above 15°C) for two hours first. If the charger still shows a fault, attempt a brief 30-second connection to a compatible 25.2V charger to nudge cell voltage above the acceptance floor, then restart a normal charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381314322522,"sku":"BWCS-ABL100VX-1","price":191.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381314355290,"sku":"BWCS-ABL100VX-2","price":226.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381314388058,"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\/stiga-325-replacement-battery-252v-6900mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
