It delivers 5000mAh (90Wh) capacity and fits the A-KS-18Li\/25 tool directly via the original slide-rail connector and BMS handshake. If the original pack no longer holds charge or fails mid-job, this unit slots in as a direct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eA-KS-18Li\/25 platform fit:\u003c\/strong\u003e\n    The A-KS-18Li\/25 uses an 18V rail with a slide-mount connector and a proprietary BMS communication line. This battery matches that connector geometry and BMS protocol — the tool recognises it without modification or adapter.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through repeated high-inrush trigger pulls simulating drill and saw motor starts. The BMS held the overcurrent threshold steady across cycles and did not trip under standard start loads.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBreak-in load protocol:\u003c\/strong\u003e\n    On first use, run the tool at half load for two cycles before full-torque applications. This lets the BMS log the motor's inrush current profile and set accurate overcurrent protection 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 Motor-Start Inrush Surge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eCordless saws and drills draw a current spike the moment the trigger is pulled — often three to five times the running current. If the BMS has not yet profiled the motor, it can read that spike as a fault and cut power instantly. This is not a defective battery; it is the protection circuit doing its job without calibration data. Running two half-load cycles first gives the BMS the reference it needs to distinguish a normal start surge from a genuine short-circuit event.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger Refusing to Recognise the Pack After Storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion packs that sit unused can self-discharge below the charger's minimum acceptance voltage — typically around 2.5V per cell. When that threshold is crossed, most LUX-TOOLS chargers blink red and refuse to initiate a charge cycle rather than risk charging a deeply discharged cell. A battery recovery charger or a charger with a \"boost\" or \"wake\" mode can bring the cell voltage back above the acceptance floor. Once each cell reads above 2.8V, a standard charger will recognise the pack and begin a normal charge cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416030642266,"sku":"BWCS-LTS180PX-1","price":116.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416030675034,"sku":"BWCS-LTS180PX-2","price":137.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416030707802,"sku":"BWCS-LTS180PX-3","price":153.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LTS180PX-1.webp?v=1779759610","url":"https:\/\/batteryweb.com\/products\/lux-tools-a-ks-18li25-replacement-battery-18v-5000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
