The original battery shipped at 1600mAh — this cell steps up to 2500mAh at the same 18V rail. More capacity means more cuts before the next charge, without any wiring or adapter changes.\u003c\/p\u003e\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCross-tool compatibility — SmallCut 300 Accu, 648844, EasyCut 42 Accu:\u003c\/strong\u003e These models share the same 18V connector and BMS interface, so one pack services both the trimmer and the hedge cutter without modification.\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 steadily under motor load and tripped cleanly at the low-voltage cutoff with no fault flags.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on a new Li-ion pack:\u003c\/strong\u003e Run a full charge before the first use.

NiMH cells discharge in a flat curve, while Li-ion holds voltage higher for longer and then drops sharply near depletion. This replacement pack includes a BMS that manages that discharge curve and protects cells from over-discharge, which NiMH packs do not require. The motor receives cleaner, more consistent voltage throughout the working session.\u003c\/p\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTrimmer won't start after swapping the battery — check the contact points first\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the trimmer doesn't respond after fitting the new pack, the most common cause is oxidation or debris on the battery contact pins inside the tool. These copper contacts corrode with outdoor exposure and break the circuit even when the battery seats firmly. Clean the contacts with a dry cloth or a cotton swab before reinserting the pack. If the unit still won't start, hold the battery in place with light pressure during startup — worn contact springs sometimes lose tension over time.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43175817281626,"sku":"BWCS-GRA420PX-1","price":80.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43175817314394,"sku":"BWCS-GRA420PX-2","price":93.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43175817347162,"sku":"BWCS-GRA420PX-3","price":103.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GRA420PX-1.webp?v=1775236244","url":"https:\/\/batteryweb.com\/products\/gardena-turbotrimmer-smallcut-300-accu-replacement-battery-18v-2500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
