It slots into the same bay as the original pack and powers the tensioning and sealing cycle on all four models. Capacity figures are from the product data — 4000mAh at 18V nominal.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBXT2-19 and BXT3 series compatibility:\u003c\/strong\u003e\n    All four models run the same 18V battery platform and share the same connector and BMS handshake protocol. The tensioning motor draws peak current at maximum strap tension, and the BMS on this pack is rated to handle that surge without nuisance tripping under normal ambient conditions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran full tensioning cycles through peak motor draw and confirmed the BMS held without cutoff. Cell balance across the pack stayed within spec through repeated discharge and recharge sequences.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCold warehouse use:\u003c\/strong\u003e\n    In temperatures below 10°C, bring the battery above that threshold before starting tensioning cycles. Cold cells have elevated internal resistance — the motor's current spike at maximum tension is enough to trigger a BMS overcurrent cutoff on a pack that hasn't warmed up.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff during the tensioning cycle on the BXT3\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe BXT3's tensioning motor pulls current sharply when the tool reaches maximum strap tension. If the battery cells are below roughly 15V under load, the BMS interprets the spike as an overload and cuts output to protect the pack. This often looks like the tool stalling mid-cycle rather than a dead battery. Charge the pack fully — resting voltage should read 20V or above on a meter before the next use.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger showing a fault light on a new or stored pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf a pack has been stored discharged for several weeks, cell voltage can drop below the charger's acceptance threshold — typically around 12V for an 18V li-ion pack. The charger rejects it rather than attempting a charge, showing a fault or red indicator. Most chargers have a recovery or \"wake\" mode; hold the charge button for five seconds or consult the charger manual for the recovery sequence. Once the pack accepts the initial trickle charge and climbs above the acceptance threshold, normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416243470426,"sku":"BWCS-OPT400PW-1","price":100.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416243503194,"sku":"BWCS-OPT400PW-2","price":117.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416243535962,"sku":"BWCS-OPT400PW-3","price":130.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OPT400PW-1.webp?v=1779761098","url":"https:\/\/batteryweb.com\/products\/signode-bxt2-19-replacement-battery-18v-4000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
