It replaces OEM part BX-10BAT and restores power to the automatic oscillometric measurement cycle. Capacity figure is sourced from product data at 54Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePress-Mate Pal 3110 and 3110P compatibility:\u003c\/strong\u003e\n    Both variants share the same 12V power rail, physical form factor, and BMS handshake protocol. A single BX-10BAT cell fits either unit without modification to the battery bay or connector orientation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the Press-Mate Pal boot sequence and full oscillometric measurement cycles. The BMS accepted the new cell, completed its verification pass, and held voltage stable through repeated cuff inflation events without triggering a low-battery interrupt.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePower-on self-test protocol:\u003c\/strong\u003e\n    After installing this battery, let the device complete its full startup self-test without interruption. The BMS runs a chemistry verification check at boot. Cutting power during this sequence causes a false battery fault flag that persists until the unit is fully rebooted and the cycle completes cleanly.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Press-Mate Pal 3110 flags low battery after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe 3110's charge IC applies a conservative acceptance threshold when it first sees a new Ni-MH cell. On the first cycle, the BMS compares the cell's internal resistance and charge curve against stored OEM baseline values. A fresh cell that hasn't been conditioned yet often reads slightly outside those thresholds, which triggers a low-battery flag even when the cell is genuinely full. Running one complete charge-discharge cycle allows the BMS to recalibrate its baseline and clear the flag on subsequent charges.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice will not 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, and the Press-Mate Pal's BMS has a minimum voltage threshold below which it refuses to initialise — this protects internal circuits but also means a deeply discharged cell looks dead to the device. If the unit shows no response at power-on, place the battery on charge for a full uninterrupted cycle before attempting to boot. Once voltage climbs back above the BMS recovery threshold — typically around 10.8V for a 12V Ni-MH pack — the device will recognise the cell and proceed through its startup sequence normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381466005594,"sku":"BWCS-CPM311MD-1","price":102.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381466038362,"sku":"BWCS-CPM311MD-2","price":117.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381466071130,"sku":"BWCS-CPM311MD-3","price":128.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CPM311MD-1.webp?v=1778901051","url":"https:\/\/batteryweb.com\/products\/colin-medical-press-mate-pal-3110-replacement-battery-12v-4500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
