The AV500 is a handheld clinical device that projects infrared light onto skin to map vein patterns for venipuncture and IV placement. This battery replaces OEM part numbers 110-00003, 120074-O, ACCUAVBA500, and BA500.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAV500 platform fit:\u003c\/strong\u003e\n    The AV500 uses a single-cell 3.7V Li-ion pack with a BMS that handshakes with the device charge IC at startup. All four OEM part numbers above share the same connector pinout, voltage rail, and BMS communication protocol — this replacement matches that configuration.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the AV500 power-on self-test sequence and confirmed the BMS passed the device's battery verification check. Charge acceptance, thermal response, and cutoff thresholds all fell within the device's expected operating range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation startup protocol:\u003c\/strong\u003e\n    After fitting this battery, let the AV500 complete its full power-on self-test without interruption. The device runs a BMS verification cycle at boot — cutting power mid-sequence registers 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\"\u003eAV500 not completing boot sequence on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe AV500 runs a hardware self-test at every startup, including a battery state check against a minimum voltage threshold. A new cell that has partially self-discharged in storage can sit just below that threshold, causing the boot sequence to stall or abort. This is not a faulty battery — it is the BMS rejecting a cell it has not yet characterised. Charge the battery fully before the first power-on, then allow the device to complete its self-test without interruption.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator not reaching 100% on the first charge cycle\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe AV500 charge IC applies a conservative current limit when it first encounters a new cell, which can cause the indicator to plateau below 100% and stop climbing. This is the charge controller applying a cautious ceiling until it has completed one full characterisation cycle — not a defective battery or faulty charger. Remove the battery, reinsert it, and start a second full charge cycle. After one complete charge-to-discharge-to-charge cycle, the IC adjusts its limit and the indicator should reach full charge normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43303978500186,"sku":"BWCS-VAA500MX-1","price":60.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43303978532954,"sku":"BWCS-VAA500MX-2","price":71.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43303978565722,"sku":"BWCS-VAA500MX-3","price":79.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VAA500MX_1.webp?v=1777520735","url":"https:\/\/batteryweb.com\/products\/veins-accuvein-av500-illuminator-replacement-battery-37v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
