Both instruments use the same voltage rail and battery form factor, making this cell a direct fit for either unit. The Z-200 and Z-500 are non-destructive elemental analysis instruments used in field and clinical material testing.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eZ-200 and Z-500 shared battery platform:\u003c\/strong\u003e\n    SciAps built both the Z-200 and Z-500 around the same 14.4V battery architecture. The connector, physical envelope, and BMS handshake protocol are identical across both models, so one cell covers either instrument.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and load cycles on XRF analyzer-class equipment. The BMS communicated state-of-charge correctly across all test cycles, and the protection circuit responded as expected under full instrument load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test procedure:\u003c\/strong\u003e\n    After installing this battery, allow the Z-200 or Z-500 to complete its full power-on self-test without interrupting the boot sequence. The instrument's BMS runs a verification routine at startup — cutting power during this phase logs a persistent battery fault that will not clear until the next complete reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice not completing boot sequence on a new battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Z-200 and Z-500 run a BMS handshake during startup that checks state-of-charge and cell voltage before allowing the instrument to reach the ready state. A new cell that shipped at storage charge — typically around 3.7V per cell — can sit just below the threshold the device expects for a confident boot. The instrument interprets this as a fault and halts the sequence. A single full charge before first use brings all cells to 4.2V and clears the condition on the next power cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alarm triggering immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS calibration issue, not a cell defect. The Z-200's charge IC applies a conservative state-of-charge model during the first few cycles, and the instrument's low-battery threshold is tuned to the OEM cell's discharge curve. A replacement cell with a slightly different internal resistance reads lower on that curve in the early cycles. Run one complete charge-discharge-charge cycle under normal instrument load, and the BMS recalibrates its capacity estimate. After that cycle, the alarm threshold tracks correctly against actual remaining charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381408071770,"sku":"BWCS-SND205MD-1","price":87.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381408104538,"sku":"BWCS-SND205MD-2","price":103.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381408137306,"sku":"BWCS-SND205MD-3","price":115.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SND205MD-1.webp?v=1778615901","url":"https:\/\/batteryweb.com\/products\/sciaps-z-200-replacement-battery-144v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
