It matches the OEM voltage rail and connector format so the mower's charging dock and BMS handshake function as expected. Capacity is 2500mAh (45Wh), sourced to match the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eR38Li \/ R50Li \/ R75Li platform fit:\u003c\/strong\u003e\n    These models share the same 18V battery bay, connector pinout, and BMS communication protocol. One replacement pack covers all three mower lines without adapter or modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through simulated blade-load draws on the bench. The BMS held charge acceptance correctly and cutoff voltages sat within the OEM protection window across repeated discharge cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSeasonal storage before first spring mow:\u003c\/strong\u003e\n    If the mower sat unused through winter, bring the battery indoors for at least 12 hours before the first run. Below 10°C, Li-ion internal resistance rises sharply — the blade motor's inrush current can trip the BMS on a cold pack before the first row is finished.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff under thick grass or wet-lawn blade load\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe blade motor on the R-series draws significantly more current through dense or wet grass than on a dry, short lawn. If the instantaneous current exceeds the BMS protection threshold, the pack shuts down mid-cut to prevent cell damage. This is not a faulty battery — it is the protection circuit doing its job. Let the pack rest for five minutes, clear any clumped cuttings from the blade channel, then restart on a drier pass.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger rejecting the pack after sitting all winter\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge slowly over months. A pack stored through winter can drop below the charger's minimum acceptance voltage — typically around 12V for an 18V pack — and the dock will show a fault or simply refuse to start a charge cycle. Place the battery in a warm room (above 15°C) for two hours first. If the charger still rejects it, check cell voltage with a multimeter at the battery terminals; anything above 10V can usually be recovered by a slow pre-charge using a compatible Li-ion charger set to a 0.1C trickle rate.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381319303258,"sku":"BWCS-GRA800PW-1","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381319336026,"sku":"BWCS-GRA800PW-2","price":59.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381319368794,"sku":"BWCS-GRA800PW-3","price":66.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GRA800PW-1.webp?v=1778899964","url":"https:\/\/batteryweb.com\/products\/gardena-124562-replacement-battery-18v-2500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
