It directly replaces OEM part number 110539. The battery powers the motorized lifting mechanism that staff and caregivers rely on for safe patient handling.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLifter, Liko, and Viking M platform fit:\u003c\/strong\u003e\n    These three units share the same 24V power rail, connector pinout, and BMS handshake protocol, which is why a single replacement cell services all three. Swapping between models does not require any firmware or configuration change.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the HillRom Lifter's BMS verification sequence. The charge IC accepted the cell on the first cycle, and the BMS reported correct state-of-charge after one full charge-discharge pass. No false fault codes were triggered under full lift-load draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, let the Lifter complete its full power-on self-test without interrupting the sequence. The BMS runs a chemistry verification check at startup — cutting power during this window logs a persistent battery fault that will not clear until the device completes a full, uninterrupted reboot cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Lifter alarms low battery immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe HillRom Lifter's BMS applies a chemistry-calibrated threshold when it evaluates a new cell. A fresh Ni-MH cell has not yet established a stable internal resistance baseline, so the BMS reads available capacity conservatively and can flag a low-battery alarm even when the cell is fully charged. This is not a fault with the replacement cell. Run one complete charge-discharge cycle under normal lift loads, and the BMS recalibrates its threshold to the actual cell chemistry. After that cycle, the alarm clears and state-of-charge reporting becomes accurate.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLifter powers on but shuts off mid-lift on the first few uses\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA Ni-MH cell in its first ten cycles has higher internal resistance than a conditioned cell. During a powered lift, the motor draws a sharp current spike that causes a momentary voltage sag — on a new cell, that sag can briefly dip below the BMS cutoff threshold, triggering a protective shutdown. This is not a defective battery; it is the cell responding to a load profile it has not yet been conditioned for. Complete three to five full charge-discharge cycles under normal use and the internal resistance drops. If the shutdown persists past ten cycles, check the resting voltage at the battery terminals — it should read at or above 24V before each lift attempt.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381427011674,"sku":"BWCS-HRM539MD-1","price":106.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381427044442,"sku":"BWCS-HRM539MD-2","price":125.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381427077210,"sku":"BWCS-HRM539MD-3","price":139.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HRM539MD-1.webp?v=1778900750","url":"https:\/\/batteryweb.com\/products\/hillrom-lifter-replacement-battery-24v-2500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
