The iPac is a handheld clinical device used in ophthalmology to measure intraocular pressure during glaucoma screening and diagnosis. Match your original part number — 16042, 16042-001, or LIP002-1RT — before installing.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eiPac platform fit:\u003c\/strong\u003e\n    The iPac runs a single-cell 3.7V Li-ion configuration with BMS handshake verification at power-on. This cell matches that voltage rail and the connector footprint, so the device firmware recognises the pack and proceeds through its startup sequence normally.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and load profiling consistent with the iPac's measurement draw. The BMS passed charge termination and low-voltage cutoff at expected thresholds. No fault flags were triggered after a full conditioning cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After installation, let the iPac complete its full power-on self-test without interruption. The device runs a BMS verification pass at startup — cutting power during this sequence can latch a false battery fault that persists until the next clean reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eiPac not completing boot sequence on new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe iPac performs a BMS handshake during boot to verify cell chemistry and minimum state of charge. A new cell shipped in partial-charge storage state can read below the firmware's boot threshold, even if the cell itself is not depleted. If the device stalls mid-boot, charge the battery to full before attempting power-on again. A complete charge cycle — not just a partial top-up — is required for the firmware to clear the threshold check and proceed.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alarm triggering immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe iPac's charge IC applies a conservative voltage threshold when it first encounters a new cell — the BMS has not yet profiled the cell's internal resistance or charge curve. This causes the device to flag a low-battery alarm even when the pack is at full charge. Run one complete charge-discharge-charge cycle before clinical use. After that conditioning pass, the BMS calibrates its state-of-charge readings to the actual cell and the alarm clears at the correct threshold.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381434024026,"sku":"BWCS-RPT160MD-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381434056794,"sku":"BWCS-RPT160MD-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381434089562,"sku":"BWCS-RPT160MD-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RPT160MD-1.webp?v=1778900788","url":"https:\/\/batteryweb.com\/products\/reichert-ipac-replacement-battery-37v-1150mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
