{"product_id":"enct4008q5v50ma","title":"Neware CT-4008Q 5V50mA Battery Testing System, ENCT4008Q5V50mA","description":"\u003cp\u003eThe Neware CT-4008Q is a high-precision battery testing system specifically designed for R\u0026amp;D labs and quality control, particularly for small-format cells like the pouch cells, coin cells, and 18650s you are working with. The \"Q\" in the model name stands for Quintuple (5) ranges, meaning each channel can automatically switch between five different current scales to maintain extreme accuracy from micro-amps up to the full rated current.\u003c\/p\u003e\n\u003cp\u003eThe CT-4008Q series is the \"low-current\" high-precision branch of Neware's 4000 series. (1) \u003cstrong\u003eVoltage Range\u003c\/strong\u003e: Typically 0V to 5V (standard for Lithium chemistries). (2) \u003cstrong\u003eCurrent Ranges\u003c\/strong\u003e: Most common configurations are 5V 10mA, 50 mA, 100mA, 1A, 6A, or 12A. (3) \u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.05% of Full Scale (FS). Because of the multi-range switching, it remains accurate even when testing at very low C-rates. (4) \u003cstrong\u003eData Acquisition\u003c\/strong\u003e: Sampling rates up to 10Hz (100ms per point), which is essential for capturing the voltage plateaus during SEI formation or Pulse tests.\u003c\/p\u003e\n\u003cp\u003eIt can be mainly used for: (1) \u003cstrong\u003eDCIR Testing (Direct Current Internal Resistance)\u003c\/strong\u003e: The software can automatically calculate the internal resistance of your pouch cells, which is a primary indicator of how well your tabs were welded and how well your electrolyte has wetted the electrodes. (2) \u003cstrong\u003eCycle Life Testing\u003c\/strong\u003e: You can program thousands of \"Charge-Rest-Discharge-Rest\" loops to see how your battery degrades over months of use. (3) \u003cstrong\u003eC-Rate Characterization\u003c\/strong\u003e: Easily test how your pouch cell performs under high power (fast discharge) versus high energy (slow discharge). (4) \u003cstrong\u003ed(Q)\/d(V) Analysis\u003c\/strong\u003e: The high precision of the 4008Q allows you to perform Differential Capacity Analysis. This helps you identify specific electrochemical reactions and phase transitions occurring inside your cell that aren't visible on a standard voltage curve.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"height: 1218.4px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"height: 47.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eENCT4008Q5V50mA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"height: 47.6px;\"\u003e\u003cem\u003ePower\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eAC110V or 220V±10%, single phase, 50\/60Hz, 40 W\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 67.2px;\"\u003e\n\u003ctd style=\"height: 67.2px;\"\u003e\n\u003cp\u003e\u003cem\u003eVoltage Features\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"height: 67.2px;\"\u003e\n\u003cul\u003e\n\u003cli\u003e25 mV ~ 5V (the minimal discharge voltage could be 0)\u003c\/li\u003e\n\u003cli\u003eAccuracy: ± 0.05% of F.S.\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 227.2px;\"\u003e\n\u003ctd style=\"height: 227.2px;\"\u003e\u003cem\u003eCurrent Features\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"height: 227.2px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eThere are three current ranges:\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e          Range 1: (5 uA - 1 mA) \u003c\/p\u003e\n\u003cp\u003e          Range 2: (1 mA - 25 mA)\u003c\/p\u003e\n\u003cp\u003e          Range 3: (25 mA - 50 mA)\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAccuracy: ± 0.05% of F.S.\u003c\/li\u003e\n\u003cli\u003eThe cut off current at the constant voltage: 2 uA (range 1);
