All three models run on the same voltage rail and share an identical physical form factor and connector. Capacity is rated at 12.95Wh — matching the original specification for these terminals.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eG3, G870, and K370 compatibility:\u003c\/strong\u003e\n    These three terminals share the same battery bay dimensions, connector pinout, and BMS communication protocol. A single GX01-spec cell covers all three 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 full charge cycles on a G3 unit, monitoring BMS handshake acceptance, charge IC behaviour during top-off, and cutoff response under combined display, printer, and wireless draw. The BMS accepted the cell within the first complete boot-charge cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst deployment tip for POS terminals:\u003c\/strong\u003e\n    After installing the battery, complete one full transaction cycle — including a receipt print — before deploying in a live environment. The terminal maps battery capacity during normal operation and requires at least one complete power cycle to calibrate the charge indicator accurately.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eReceipt printer causing battery drain on the G3 and K370\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe thermal printer inside these terminals draws a sharp current spike each time it fires — typically the highest single load event the battery handles. On a degraded cell, this spike can sag the voltage enough to trip the BMS overcurrent protection and reboot the terminal mid-receipt. A fresh GX01-spec cell with full capacity handles this spike without voltage sag. If the terminal still reboots during printing after a battery swap, check that the charge IC has completed a full top-off cycle before blaming the cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTerminal not completing PCI boot sequence after battery installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe G3 runs a PCI security boot sequence on startup that requires a stable, verified power source. A brand-new cell can fail this check if the BMS handshake hasn't been accepted yet — the terminal interprets an unverified battery as an unstable supply and halts boot. This is not a faulty battery. Connect the terminal to the charger, allow one full charge cycle to complete, then power on again. The BMS handshake completes during that first charge and the boot sequence proceeds normally from that point.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415930241114,"sku":"BWCS-TLK370BL-1","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415930273882,"sku":"BWCS-TLK370BL-2","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415930306650,"sku":"BWCS-TLK370BL-3","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TLK370BL-1.webp?v=1779758145","url":"https:\/\/batteryweb.com\/products\/tactilion-g3-replacement-battery-74v-1750mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
