It replaces OEM part 244760-00 and fits the BDGL18K-2, XTC183BK, XTC18BK, and over 160 additional compatible models on the same 18V platform. Voltage and capacity match the original spec.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBDGL1800 platform fit:\u003c\/strong\u003e\n    These models share a common 18V rail, the same slide-in connector footprint, and a compatible BMS handshake. One pack works across the full 18V line because the cell voltage window and communication protocol are consistent across these SKUs.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through full charge and load cycles on a BDGL1800 trimmer head. The BMS held stable under motor-start inrush and did not trip on repeated trigger pulls at full throttle. Cell balance stayed within spec across five discharge cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst two cycles on string trimmer use:\u003c\/strong\u003e\n    Run the trimmer at half-line-feed load for the first two cycles before tackling dense grass or heavy edging. This lets the BMS log the motor's inrush current signature and set accurate overcurrent thresholds before you push maximum draw.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff on trigger pull in the BDGL1800\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe BDGL1800 motor draws a sharp inrush spike the instant the trigger engages — often two to three times the running current. A new pack from storage may have a conservative overcurrent threshold that trips on this spike before the BMS has profiled the load. The result is an immediate shutoff that looks like a dead battery but isn't. Running two partial cycles trains the BMS to the motor's actual startup draw and raises the threshold accordingly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger stays solid red and never switches to green on a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter extended storage, individual cells can drop below 2.5V — the threshold most Black \u0026amp; Decker 18V chargers require before entering full charge mode. A solid red light with no transition usually means the charger is refusing the pack, not that the pack is dead. Leave the pack on the charger for 20 to 30 minutes; some chargers include a trickle-recovery mode that will slowly bring cells back above 2.8V before switching to normal charge. If the light hasn't changed after 45 minutes, check cell voltage at the pack terminals — anything above 10V total across the 18V pack means recovery is still possible.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416013570138,"sku":"BWCS-BPS180PW-1","price":81.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416013602906,"sku":"BWCS-BPS180PW-2","price":95.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416013635674,"sku":"BWCS-BPS180PW-3","price":106.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BPS180PW-1.webp?v=1779759461","url":"https:\/\/batteryweb.com\/products\/black-decker-bdgl1800-replacement-battery-18v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
