It fits Gardena's Accu45 platform using the proprietary Gardena connector. Capacity is 3600mAh (17.28Wh) — matching the original specification.\u003c\/p\u003e\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAccu45 platform compatibility:\u003c\/strong\u003e The 8816 and other Accu45-series trimmers share a common 4.8V voltage rail and proprietary Gardena connector, so one battery pack covers the line.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e We ran full charge\/discharge cycles — the cells held voltage under load and the pack released cleanly at low-voltage cutoff without dropping the trimmer mid-cut.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNiMH storage before first use:\u003c\/strong\u003e NiMH packs ship partially charged — run two or three full charge\/discharge cycles before regular use to condition the cells and reach full rated capacity.\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \u003chr class=\"bpw-desc-divider\"\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy cell count matters in a 4.8V NiMH pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH cells run at 1.2V nominal, so a 4.8V pack uses four cells in series. All four must hold consistent capacity — one weak cell drags the whole pack down and causes premature cutoff. These cells are matched before assembly to keep internal resistance balanced across the pack.\u003c\/p\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTrimmer cuts out suddenly — what's happening and how to fix it\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA hedge trimmer that stops abruptly mid-use is usually hitting the low-voltage protection cutoff early. In degraded NiMH packs, one or more cells lose capacity and the pack voltage collapses under the motor load before the other cells are depleted. A fresh, matched pack resolves this — the cells reach cutoff together rather than one cell dragging the rest down early.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43175825178714,"sku":"BWCS-GRA088PW-1","price":30.38,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43175825211482,"sku":"BWCS-GRA088PW-2","price":36.46,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43175825244250,"sku":"BWCS-GRA088PW-3","price":41.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GRA088PW-1.webp?v=1775236297","url":"https:\/\/batteryweb.com\/products\/gardena-8816-replacement-battery-48v-3600mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
