It matches OEM part numbers V3M2, 40100023, and B16. Fits the same physical bay and connector as the factory battery.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVega 3000 and 3000P compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay dimensions, 3.7V supply rail, and BMS handshake protocol — this cell works in both without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through a full boot sequence on the Vega 3000. The BMS handshake completed on first power-on, the charge IC entered normal top-off mode, and the terminal reached the transaction-ready screen without error flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst deployment on a live countertop:\u003c\/strong\u003e\n    Complete one full transaction cycle before using the terminal in a live environment. The Vega 3000 maps battery capacity during normal operation and needs at least one complete power cycle to calibrate the charge indicator correctly.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTerminal rebooting mid-transaction after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Vega 3000 draws a short current spike when the receipt printer fires — this can trip a new battery's BMS overcurrent protection if the cell hasn't completed its first full charge cycle. The BMS on a freshly installed cell is in a conservative state until it has mapped the load profile. Charge the battery to 100% before the first transaction run. After one complete charge-discharge cycle, the BMS adjusts its overcurrent threshold and the mid-sale reboot stops.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTerminal stuck at a blank screen and not completing the PCI boot sequence\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Vega 3000 runs a PCI-compliant security boot that draws more current than standby — if the new cell hasn't been accepted by the BMS yet, voltage sags below the terminal's minimum operating threshold before the boot sequence finishes. This looks like a dead device but is a BMS initialisation issue. Connect the terminal to the charger, leave it for a full charge cycle without interruption, then power on while still connected to the charger. Once the boot completes with external power, the BMS registers the load profile and the terminal boots normally from battery at 3.7V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415931289690,"sku":"BWCS-CTA320SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415931322458,"sku":"BWCS-CTA320SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415931355226,"sku":"BWCS-CTA320SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CTA320SL-1.webp?v=1779758085","url":"https:\/\/batteryweb.com\/products\/castles-vega-3000-replacement-battery-37v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
