It fits devices running OEM part numbers 340426, 60050, B11734, M3252795-A, OM0117, and OM11734. The battery powers the portable negative pressure wound therapy unit, maintaining suction output during patient mobility.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eInfo VAC and VAC Freedom platform fit:\u003c\/strong\u003e\n    Both units share the same 12V battery rail, connector pinout, and BMS handshake protocol. A single cell format covers both devices without modification or adapter.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through the Info VAC's charge IC and confirmed the BMS completed cell recognition without fault codes. Charge termination triggered correctly at full capacity on the second cycle.\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. The Info VAC runs a BMS verification sequence at startup — cutting power during this window registers a 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\"\u003eWhy the Info VAC alarms low battery immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Info VAC's charge controller compares cell voltage against an OEM-calibrated threshold during self-test. A new Ni-MH cell sits slightly below peak resting voltage until it completes one full charge-discharge cycle. The BMS interprets this as a marginal cell and triggers the low-battery alarm even when the pack is fully charged. Run one complete cycle — full charge, allow the device to draw the battery down through normal use, then recharge fully — before trusting the indicator in a clinical setting.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator stalls below 100% on first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Info VAC's charge IC applies a conservative current limit when it encounters a new or previously discharged Ni-MH cell. This causes the charge indicator to plateau and appear stuck, typically between 85–95%. The cell is still accepting charge — the IC is simply rate-limiting until internal resistance normalises. Let the charge cycle complete uninterrupted; resting voltage on a full Ni-MH cell at 12V nominal should read approximately 13.2–13.8V across the pack terminals before use.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381362032730,"sku":"BWCS-KTM325MD-1","price":81.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381362065498,"sku":"BWCS-KTM325MD-2","price":95.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381362098266,"sku":"BWCS-KTM325MD-3","price":106.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KTM325MD-1.webp?v=1778900267","url":"https:\/\/batteryweb.com\/products\/kci-info-vac-therapy-unit-replacement-battery-12v-2100mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
