It slots into the internal battery bay and powers the device during mains outages or patient transport. Voltage, chemistry, and footprint match the OEM specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eShared platform across AVI pump range:\u003c\/strong\u003e\n    The 110, 100, 200A, and Micro 285 all run on the same 12V SLA architecture. That shared voltage rail and connector standard is why one cell covers the full lineup — the BMS in each unit draws from the same charge and cutoff thresholds.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge-discharge on a 12V SLA load profile and monitored BMS response at both cutoff and recovery thresholds. The cell passed charge acceptance and low-voltage recovery within expected parameters.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, allow the pump to complete its full power-on self-test without interruption. AVI infusion pumps run a BMS verification sequence at startup — cutting power during that sequence registers a false battery fault that persists until the next clean 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 AVI pump shows a battery fault after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAVI infusion pumps store a battery condition flag that the BMS updates after each completed charge-discharge cycle. A new cell has no cycle history in that register, so the device may flag a fault even when the cell is fully charged. The fix is one complete charge-discharge cycle run outside clinical duty — let the pump draw the cell down to its low-voltage cutoff, then recharge to 100%. After that cycle, the BMS registers valid history and clears the fault flag.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAVI pump will not power on after battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSealed lead acid cells self-discharge during storage, and if the terminal voltage drops below approximately 10.5V, the BMS enters a protection state and blocks normal startup. The pump shows nothing — no display, no alarm. Connect the pump to mains power and leave it on charge for a minimum of 24 hours before attempting to power on from battery alone. This allows the charge IC to trickle the cell back above the BMS recovery threshold, typically 11.8V, before switching to bulk charge mode.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381384577114,"sku":"BWCS-SHT160MD-1","price":310.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381384609882,"sku":"BWCS-SHT160MD-2","price":370.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381384642650,"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\/avi-110-replacement-battery-12v-2300mah-sealed-lead-acid","provider":"BatteryWeb","version":"1.0","type":"link"}
