It matches the SNLB-264 OEM part number and fits the same battery bay without modification. Capacity is rated at 27.75Wh, consistent with the original cell specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eV7, H8, and V8 platform fit:\u003c\/strong\u003e\n    These three models share a common battery bay geometry, connector pinout, and BMS handshake protocol. The shared power architecture means one cell SKU covers the full scanner family without adapters or wiring changes.\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 discharge on a medical-grade load tester. The BMS negotiation completed correctly, charge termination triggered at the expected voltage, and protection circuits responded normally to overload simulation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, allow the scanner to complete its full power-on self-test without interruption. Medical ultrasound devices run a BMS verification routine at startup — cutting power during this sequence logs a false battery fault that persists until the next full reboot cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice not completing boot sequence on new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eHandheld ultrasound scanners run a power integrity check before completing boot. A new Li-Polymer cell can sit just below the BMS pass threshold if it has partially self-discharged during storage. The device reads this as a power fault and halts the sequence before reaching the main interface. Charge the battery fully before the first boot attempt — the scanner's charge IC may apply a conservative pre-charge trickle to new cells, so allow at least a full uninterrupted charge cycle before drawing conclusions about battery condition.\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\"\u003eThis alarm occurs when the BMS compares the new cell's discharge curve against the OEM chemistry profile stored in firmware. A fresh cell's internal resistance profile differs slightly from a conditioned one, and the scanner interprets the early voltage response as low capacity. This is not a faulty battery — it is the BMS calibration window. Run one complete charge-to-discharge-to-full-charge cycle before clinical use, and the firmware will update its reference curve. After that cycle, the alarm threshold aligns correctly and the false trigger stops.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381436448858,"sku":"BWCS-CRV800MD-1","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381436481626,"sku":"BWCS-CRV800MD-2","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381436514394,"sku":"BWCS-CRV800MD-3","price":47.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CRV800MD-1.webp?v=1778900838","url":"https:\/\/batteryweb.com\/products\/carejoy-v7-replacement-battery-111v-2500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
