It matches the OEM part number 103.138.06 and slots into the same battery bay as the original pack. Voltage and capacity are spec-matched to keep the blade motor and BMS operating within their rated parameters.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePOWXG6305 platform fit:\u003c\/strong\u003e\n    The POWXG6305 runs an 18V motor rail with a specific connector and BMS handshake. This pack meets that voltage rail and communicates correctly with the mower's onboard protection circuit — the mower won't arm the blade motor unless the BMS handshake completes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack under simulated blade-load current draws, including inrush spikes typical of thick-grass cutting passes. The BMS held the discharge window without nuisance trips across multiple load cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSeasonal storage tip:\u003c\/strong\u003e\n    Before the first cut of spring, 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 can trip the BMS on a cold pack before the cells have warmed up.\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 loads\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe POWXG6305 blade motor draws a sharp inrush current each time it bites into dense or wet grass — often two to three times the steady-state draw. If the pack's BMS reads that spike as an overcurrent event, it cuts output to protect the cells. This trips the mower off mid-row even though the battery still holds charge. Overlapping mowing rows by less and keeping the blade height one notch higher in wet conditions reduces the inrush magnitude enough that the BMS stays armed through the pass.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger showing a fault light after winter storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion packs self-discharge at roughly 2–3% per month in storage. A pack left in a cold garage from October to March can drop below the charger's acceptance voltage threshold — typically around 12–13V on an 18V pack — and the charger flags it as a fault rather than entering charge mode. The fix is a short \"wake\" charge: place the pack in the charger, wait 30 seconds, remove it, then reinsert. Some chargers will then detect the cells and begin a trickle cycle. If the fault light persists after three attempts, measure pack voltage with a multimeter — any reading below 10V indicates cell damage from deep discharge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381278998618,"sku":"BWCS-PWG630PW-1","price":76.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381279031386,"sku":"BWCS-PWG630PW-2","price":90.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381279064154,"sku":"BWCS-PWG630PW-3","price":101.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PWG630PW-1.webp?v=1778899919","url":"https:\/\/batteryweb.com\/products\/powerplus-powxg6305-replacement-battery-18v-2500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
