Capacity steps up from the original 1500mAh (27Wh) to 2500mAh (45Wh), giving the motor more energy per charge cycle without changing the voltage rail.\u003c\/p\u003e\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCompatibility — Comfort Wand-Schlauchbox 35 (8025-20):\u003c\/strong\u003e Both listed models share the same 18V connector interface and BMS handshake, so the pack seats and communicates correctly with the reel's motor controller.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e We ran full charge\/discharge cycles — the BMS held voltage steady under motor load and triggered the low-voltage cutoff cleanly without dropping into an unrecoverable state.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use tip for Li-ion hose reel batteries:\u003c\/strong\u003e Run two or three full charge\/discharge cycles before relying on the pack for heavy use — Li-ion cells in motor applications reach stable capacity after a brief break-in period.\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \u003chr class=\"bpw-desc-divider\"\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy a higher-capacity pack works in the same hose reel\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe reel's motor controller regulates draw based on voltage, not pack size. Swapping from 1500mAh to 2500mAh keeps the same 18V rail the controller expects. The larger cell count simply stores more energy, so the motor has more reserve to retract a full 35-metre hose under tension. No firmware or hardware changes are needed.\u003c\/p\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eReel stalls mid-retract — what causes it and how to fix it\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the hose stops partway through retraction, the most common cause is voltage sag on an aging or deeply discharged pack — the BMS trips the cutoff before the hose is fully wound. Fully charge the replacement battery before the first use. If the original pack was triggering this symptom, the higher 45Wh capacity in this replacement provides more headroom before the BMS reaches its cutoff threshold.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43175823704154,"sku":"BWCS-GRA802PX-1","price":102.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43175823736922,"sku":"BWCS-GRA802PX-2","price":121.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43175823769690,"sku":"BWCS-GRA802PX-3","price":134.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GRA802PX-1.webp?v=1775236298","url":"https:\/\/batteryweb.com\/products\/gardena-comfort-wand-schlauchbox-35-roll-up-automatic-li-replacement-battery-18v-2500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
