It slots in as a direct swap for part number 23149-01 — the original cell used in TOPAZ units deployed at retail point-of-sale. The battery powers the terminal during operation and keeps it running through brief power interruptions at the checkout counter.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTOPAZ platform fit:\u003c\/strong\u003e\n    The TOPAZ uses a 14.4V multi-cell Ni-MH pack with a specific connector and BMS handshake. Cells outside this voltage range will not complete the terminal's internal power negotiation — the unit will refuse to boot or will fault on startup.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through a full TOPAZ boot sequence and live transaction simulation. The BMS accepted the handshake without faulting, the charge IC entered normal top-off mode as expected, and the terminal completed PCI boot without interruption.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst deployment tip for TOPAZ:\u003c\/strong\u003e\n    After installation, complete one full transaction cycle before putting the terminal into a live queue. The TOPAZ 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\"\u003eWhy the TOPAZ reboots mid-transaction after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe TOPAZ receipt printer draws a sharp current spike when it fires — enough to trip the BMS overcurrent threshold on a pack that hasn't completed its first full charge cycle. The terminal reads this as a voltage fault and resets. This is not a faulty battery. Charge the pack fully before first use, then run one complete transaction including a printed receipt. After that cycle, the BMS calibrates its cutoff curve to the terminal's actual load profile and the reboot behaviour stops.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTerminal not powering on after sitting unused in a drawer\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge at roughly 1–3% per day. A TOPAZ terminal left unused for several weeks can drop the pack below the BMS recovery threshold — typically around 10.5V for a 14.4V Ni-MH pack. At that level, the BMS locks the cell out as a protection measure and the terminal shows no response on power-up. Connect the terminal to mains power and leave it on charge for a minimum of 4 hours before attempting to boot. Most packs recover fully from this state if the cell voltage hasn't dropped below 9V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415939579994,"sku":"BWCS-VFT901BL-1","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415939612762,"sku":"BWCS-VFT901BL-2","price":73.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415939645530,"sku":"BWCS-VFT901BL-3","price":81.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VFT901BL-1.webp?v=1779758255","url":"https:\/\/batteryweb.com\/products\/verifone-topaz-replacement-battery-144v-1500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
