It replaces OEM part numbers 10\/5000DH-C-SL and OM0104. The battery powers the stairlift's drive motor and onboard control systems.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAcorn 180 and 80 Stairlift platform compatibility:\u003c\/strong\u003e\n    These models share the same 12V battery rail, connector format, and BMS handshake protocol. A single pack covers the full range because the control board draws from the same voltage bus regardless of track length or chair configuration.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a stairlift control board. The BMS accepted the pack without fault codes, completed its verification handshake, and the motor drive circuit responded normally under load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, let the stairlift complete its full power-on self-test without interrupting power. The control board runs a BMS verification sequence at startup. Cutting power mid-sequence sets a persistent battery fault that does not clear until the next 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 Acorn Stairlift triggers a low-battery alarm with a new pack installed\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Acorn stairlift control board uses a charge threshold calibrated to its OEM cell's internal resistance profile. A new Ni-MH cell starts with a slightly different resistance signature than a conditioned pack. The BMS reads this as a sub-threshold state of charge and trips the alarm even when the battery is fully charged. One complete charge-discharge cycle normalises the cell's resistance curve, and the alarm clears on subsequent use.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eStairlift won't power on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge during storage. If this pack sat for several months before installation, its resting voltage may have dropped below the stairlift BMS's minimum recovery threshold — typically around 10.5V for a 12V system. At that voltage the BMS locks out the circuit as a protection measure and the chair appears completely dead. Connect the charger and leave it on a full uninterrupted charge cycle before attempting to power the unit on. If the charger confirms a completed charge and the unit still does not respond, check the pack voltage directly at the battery terminals — it should read at least 12.0V before the BMS will allow the motor circuit to activate.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381417672794,"sku":"BWCS-ACS180MD-1","price":130.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381417705562,"sku":"BWCS-ACS180MD-2","price":154.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381417738330,"sku":"BWCS-ACS180MD-3","price":172.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ACS180MD-1.webp?v=1778900660","url":"https:\/\/batteryweb.com\/products\/acorn-stairlift-replacement-battery-12v-5000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
