It fits Honda's Universal Cordless System lineup, including the HRX 476 XB VE lawnmower and HHH 36 AXB hedge trimmer. Voltage matches the 36V rail these tools run on; capacity comes in at 5000mAh and 180Wh.\u003c\/p\u003e\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eShared platform compatibility:\u003c\/strong\u003e Honda's Universal Cordless System uses the same 36V connector and BMS handshake across handheld tools and lawnmowers, so one battery shell covers the full range of compatible models.\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 load and triggered the low-voltage cutoff cleanly without thermal events.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on a new pack:\u003c\/strong\u003e Run a full charge before the first use on your lawnmower or trimmer — lithium-ion cells perform more consistently once the BMS completes its first full calibration cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \u003chr class=\"bpw-desc-divider\"\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the 36V rail matters for Honda cordless lawnmowers\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eHonda's HRX and cordless handheld range runs a 36V architecture because it balances motor torque demand with cell count. Dropping below 36V nominal causes the tool's BMS to cut power early as a protection measure. A correctly rated replacement pack keeps the voltage window within spec, so the motor draws current at the intended rate across the full discharge curve.\u003c\/p\u003e\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery not recognised by the charger — what's happening and how to fix it\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the Honda charger flashes an error on a new pack, the cells are likely too cold or the BMS hasn't been initialised. Li-ion packs below 10°C can trigger a charger lockout as a safety measure. Bring the battery to room temperature, wait 20 minutes, then reconnect. If the fault persists, briefly seat the pack in the tool and press the trigger — this can wake a deeply discharged BMS before returning it to the charger.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43175815577690,"sku":"BWCS-BME360PX-1","price":190.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43175815610458,"sku":"BWCS-BME360PX-2","price":225.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43175815643226,"sku":"BWCS-BME360PX-3","price":252.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BME360PX-1.webp?v=1775236243","url":"https:\/\/batteryweb.com\/products\/honda-dp3660xa-replacement-battery-36v-5000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
