These trimmers cut along lawn borders and pathways using a reciprocating blade powered by a low-voltage NiMH pack. Voltage is 4.8V, capacity is 3600mAh (17.28Wh).\u003c\/p\u003e\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eConfirmed fit — 8802, 8816, 8818:\u003c\/strong\u003e All three Rasenkantenschere models share the same 4.8V voltage rail, Accu 75 connector format, and BMS handshake — one pack covers the full range.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e We ran full charge and discharge cycles — the BMS held voltage steady under blade load and triggered the low-voltage cutoff cleanly without over-discharging the cells.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on Ni-MH — do this before use:\u003c\/strong\u003e Run two to three full charge and discharge cycles before relying on the pack. Ni-MH cells need conditioning to reach rated capacity, especially after sitting in storage.\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \u003chr class=\"bpw-desc-divider\"\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy capacity matters more than voltage on a 4.8V trimmer\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAt 4.8V, the trimmer blade draws consistent current through short bursts. A higher mAh rating — 3600mAh here versus older 2000mAh OEM packs — means the cells sustain current delivery longer before voltage sag sets in. Voltage sag is what makes the blade slow or stall mid-cut, not a dead battery. More capacity keeps the cells operating in their efficient range across the session.\u003c\/p\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBlade slowing down mid-trim — what causes it and how to fix it\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the blade loses speed partway through a trim session, the original battery's cells have likely degraded and can no longer hold voltage under load. This is a cell-level issue, not a charger or motor fault. Swapping to a fresh pack with healthy cells restores full blade speed immediately. If the problem continues with a new battery, check the charger output — an undercharging unit will never fully restore cell capacity.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43175826554970,"sku":"BWCS-GRA881PW-1","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43175826587738,"sku":"BWCS-GRA881PW-2","price":48.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43175826620506,"sku":"BWCS-GRA881PW-3","price":53.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GRA881PW-1.webp?v=1775236298","url":"https:\/\/batteryweb.com\/products\/gardena-rasenkantenschere-8802-replacement-battery-48v-3600mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
