It powers the electric motor that drives the lifting mechanism during patient transfers. Fits the 1493139 model directly using OEM part number 20HHR-260SCP.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLifter Robin 1493139 platform fit:\u003c\/strong\u003e\n    The 1493139 series runs a 24V motor rail with a BMS handshake tuned to Ni-MH discharge curves. Substituting a different chemistry breaks that handshake and triggers a false fault. This cell matches the voltage, chemistry, and connector required by the lift's control board.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through full charge and load discharge on the 1493139 platform. The BMS accepted the cell, completed its verification sequence, and held voltage under motor-start load without tripping a cutoff event.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, let the lift complete its full power-on self-test without interrupting the sequence. The 1493139 runs a BMS verification at startup — cutting power mid-cycle writes a fault flag that persists until the next clean reboot, not until the next charge.\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 Robin 1493139 alarms low battery immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 1493139's charge IC applies a conservative capacity threshold on first contact with a new Ni-MH cell. Until the BMS logs one complete charge-discharge cycle, it treats the cell as unverified and flags capacity as insufficient even when the cell is physically full. This is a learn-cycle gate, not a fault. Run one full charge-discharge cycle before clinical use and the alarm clears on subsequent charges.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLifter Robin 1493139 not powering on after the battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge at roughly 1–2% per day. A cell stored for several months can drop below 18V — the minimum threshold the 1493139's BMS needs to initialise. At that voltage, the control board sees no valid power source and will not attempt a boot. Connect the charger and hold for a full charge cycle before pressing power. If the charger does not recognise the cell either, check terminal voltage with a multimeter — a reading below 16V means the cell has passed the BMS recovery floor and the battery requires replacement rather than recovery charging.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381370978394,"sku":"BWCS-IVS139MD-1","price":140.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381371011162,"sku":"BWCS-IVS139MD-2","price":166.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381371043930,"sku":"BWCS-IVS139MD-3","price":185.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IVS139MD-1.webp?v=1778900351","url":"https:\/\/batteryweb.com\/products\/invacare-lifter-robin-type-1493139-replacement-battery-24v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
