It fits portable medical devices that use the NP2.3-12FR form factor. Dimensions are 178.00 x 66.60 x 35.00mm — confirm against your existing cell before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNP2.3-12FR platform fit:\u003c\/strong\u003e\n    Devices spec'd to the NP2.3-12FR use a standardised 12V sealed lead acid footprint with a fixed terminal layout. Any replacement must match voltage, physical size, and terminal polarity exactly — a mismatch triggers an immediate BMS fault on most medical platforms.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge-discharge on a 12V SLA test rig and monitored BMS handshake at load. The cell held voltage within spec across the discharge curve and the BMS passed no false fault flags under normal draw conditions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, allow the device to complete its full power-on self-test without interruption. Medical devices run BMS verification at startup — cutting power during this sequence logs a false battery fault that persists until the next complete reboot cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMedical device alarming low battery with a freshly charged replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eSome medical platforms set their low-battery alarm threshold against a calibrated OEM cell. A new replacement cell's internal resistance profile differs slightly from a conditioned cell, and the device charge IC reads this as insufficient capacity. The BMS needs at least one full charge-discharge cycle before it accurately maps the new cell's characteristics. Run one complete cycle before treating any alarm as a genuine fault.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice will not power on after the replacement cell sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSealed lead acid cells self-discharge in storage and can drop below the BMS recovery threshold — typically around 10.5V for a 12V cell. If the battery shipped or sat unused for several months, the BMS may block power-on entirely as a protection response. Connect the device to mains power and allow a supervised trickle charge for at least four hours before attempting to boot. Check open-circuit voltage first — if it reads below 10.5V, a slow recovery charge is required before the BMS will re-enable output.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381387165786,"sku":"BWCS-SHT160MD-1","price":310.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381387198554,"sku":"BWCS-SHT160MD-2","price":370.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381387231322,"sku":"BWCS-SHT160MD-3","price":415.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SHT160MD-1.webp?v=1778900511","url":"https:\/\/batteryweb.com\/products\/genesis-np23-12fr-replacement-battery-12v-2300mah-sealed-lead-acid","provider":"BatteryWeb","version":"1.0","type":"link"}
