It fits the 6210 portable POS unit used by merchants for card transactions. Swap it in when the original cell no longer holds charge through a shift.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLoyalPay 6210 fit:\u003c\/strong\u003e\n    The 6210 terminal runs a single-cell 3.7V rail. This cell matches that voltage, the physical connector pinout, and the BMS communication protocol the terminal expects on boot. No firmware flags or hardware modifications needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through repeated transaction loads — display on, wireless active, receipt printer firing. The BMS held stable under combined draw spikes and cut off cleanly at the low-voltage threshold without causing a mid-transaction reboot.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-deployment tip for the 6210:\u003c\/strong\u003e\n    After fitting the battery, complete at least one full transaction cycle before going live. The terminal maps battery capacity during normal operation and needs 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 not completing PCI boot sequence after battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe 6210 runs a PCI security check on every power-up. A freshly installed cell may not yet have a confirmed BMS handshake with the terminal's charge controller, causing the boot sequence to stall or loop. This is not a faulty battery — it's the terminal waiting for a validated charge state. Plug into the charger, let the unit reach at least 3.9V, then power on from a connected state for the first boot.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery indicator stuck at 99% after first charge completes\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNew lithium-ion cells arrive partially charged, and the 6210's charge IC enters a top-off phase rather than a full charge cycle on first use. The indicator sits at 99% because the terminal hasn't logged a complete charge curve for this cell yet. Run the battery down through normal use until the terminal prompts a low-battery warning, then charge uninterrupted to 100%. After that single calibration cycle, the indicator tracks accurately.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415926866010,"sku":"BWCS-NEP6210BL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415926898778,"sku":"BWCS-NEP6210BL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415926931546,"sku":"BWCS-NEP6210BL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NEP6210BL-1.webp?v=1779758086","url":"https:\/\/batteryweb.com\/products\/loyalpay-6210-replacement-battery-37v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
