Both units run on the same 7.4V two-cell configuration, so one part number covers both. Capacity sits at 18.5Wh — matched to the original spec.\u003c\/p\u003e\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCompatibility across 8803 and 8824:\u003c\/strong\u003e Both models share the same voltage rail, connector pinout, and BMS communication protocol, which is why a single replacement cell pack works across the 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 load and triggered the low-voltage cutoff cleanly without requiring a manual reset.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge after long storage:\u003c\/strong\u003e If the pack has been sitting discharged, run a full slow charge before first use — Li-ion cells stored at low voltage can take a conditioning cycle to recover full capacity.\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \u003chr class=\"bpw-desc-divider\"\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCell dimensions and why they matter for fit\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe pack measures 66.50 x 37.10 x 19.20mm. Gardena's battery housing on these models has tight tolerances — even a few millimetres over spec will prevent the latch from seating. These cells are cut to the original footprint, so the housing closes and locks the same way as the factory pack.\u003c\/p\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTool powers on but cuts out immediately under load\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis usually means the BMS is triggering an overcurrent fault — common when the original battery has degraded cells that can't sustain the current draw the motor demands. The replacement pack uses fresh cells rated to handle the load profile of these Gardena units. Seat the battery firmly, run a full charge first, then test under normal operating conditions.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43175818690650,"sku":"BWCS-GRS800PW-1","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43175818723418,"sku":"BWCS-GRS800PW-2","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43175818756186,"sku":"BWCS-GRS800PW-3","price":44.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GRS800PW-1.webp?v=1775236275","url":"https:\/\/batteryweb.com\/products\/gardena-8803-replacement-battery-74v-2500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
