The RV-E8 uses a removable battery module that slots into the Vario platform system — this cell pack matches the original voltage rail and physical format. Capacity is rated at 17.28Wh.\u003c\/p\u003e\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVario platform compatibility:\u003c\/strong\u003e Wolf Garten's Vario system uses a shared battery module format across its cordless garden tools — the RV-E8 draws from the same 4.8V connector and BMS architecture as other tools in that line.\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 cutting load and triggered the low-voltage cutoff cleanly without dropping the cell below safe thresholds.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge after fitting:\u003c\/strong\u003e Ni-MH cells benefit from a full charge before first use.

A higher mAh rating at this voltage means more charge stored per cycle. The Ni-MH chemistry also tolerates the shallow discharge patterns typical of short garden tasks without the memory-effect penalties seen in older Ni-Cd packs.\u003c\/p\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eShear losing power mid-session — what's causing it\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the RV-E8 slows noticeably before the battery reads fully discharged, the original cell pack has likely developed voltage sag from cell degradation. Aged Ni-MH cells can no longer hold voltage under even light load, so the BMS cuts power early as a protection response. Fitting a fresh cell pack with intact internal resistance resolves this — the blade returns to full speed and the BMS cutoff triggers at the correct endpoint.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43175825080410,"sku":"BWCS-GRA088PW-1","price":30.38,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43175825113178,"sku":"BWCS-GRA088PW-2","price":36.46,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43175825145946,"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\/wolf-garten-vario-rv-e8-replacement-battery-48v-3600mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
