It fits the TTM-50003 and TTM-00536 survey tablet platforms used in restaurant and hospitality feedback terminals. Capacity is sourced from product data at 56.24Wh — not estimated from web references.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTTM-50003 and TTM-00536 platform fit:\u003c\/strong\u003e\n    Both models share the same ZP100 battery bay, connector pinout, and BMS handshake protocol. A single cell configuration at 7.6V nominal covers the voltage rail for both units without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through full charge and discharge cycles on a ZiOSK terminal and monitored BMS communication. The protection circuit responded correctly to charge termination and low-voltage cutoff — no false shutdowns or error flags during the session.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the ZiOSK tablet:\u003c\/strong\u003e\n    After fitting this battery, run the tablet through one full charge cycle before returning it to floor service. The ZiOSK firmware maps battery state during the first complete charge, and skipping this step causes the percentage indicator to display incorrectly during the first several operational sessions.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the ZiOSK terminal shuts down at survey launch despite showing charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen a guest taps to start a survey, the tablet wakes the display, re-initialises the touch layer, and polls active sensors simultaneously. That combined draw spikes current demand for 200–400ms. If the battery's BMS protection threshold is set conservatively — as it is on aging cells — this spike trips a soft cutoff before the OS can log a low-battery event. The terminal shuts down cleanly, which is why it looks like a software crash rather than a power issue. A fresh pack with healthy internal resistance handles the surge without hitting the cutoff threshold.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eZiOSK tablet not powering on after sitting unused in a hospitality stockroom\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge at roughly 2–3% per month, and the ZP100 pack has no trickle keep-alive when the tablet is off. After several months in storage, cell voltage can drop below the BMS recovery floor — typically around 2.5V per cell — which locks the pack in a protective sleep state. The tablet won't respond to the power button because the BMS won't pass current to the board. Connect the original ZiOSK charger and leave it for 30–60 minutes without pressing anything — most BMS circuits will re-initialise once the charger pushes voltage above the 3.0V-per-cell recovery threshold.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360674906202,"sku":"BWCS-ZSK100SL-1","price":78.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360674938970,"sku":"BWCS-ZSK100SL-2","price":91.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360674971738,"sku":"BWCS-ZSK100SL-3","price":101.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZSK100SL-1.webp?v=1778616178","url":"https:\/\/batteryweb.com\/products\/ziosk-ttm-50003-replacement-battery-76v-7400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
