While standard cyclers measure capacity and cycle life, the SD (Self-Discharge) model is engineered specifically to quantify the minute electrochemical leakage that occurs when a battery is at rest.\u003c\/p\u003e\n\u003cp\u003eThe \"SD\" variant prioritizes voltage stability and current resolution over raw power. (1) \u003cstrong\u003eVoltage Accuracy\u003c\/strong\u003e: 7-digit resolution with a stability of ±0.01% FS. This extreme precision is required to detect millivolt drops over long rest periods. (2) \u003cstrong\u003eCurrent Resolution\u003c\/strong\u003e: 0.1 μA (100 nA). It can perceive the tiniest fluctuations in parasitic current. (3) \u003cstrong\u003eCurrent Range\u003c\/strong\u003e: 0 to 300 mA (optimized for small-format pouch and coin cells). (4) \u003cstrong\u003eInput Impedance\u003c\/strong\u003e: ≥1000 MΩ. High impedance is critical so that the tester itself doesn't \"drain\" the battery while trying to measure its self-discharge. (5) \u003cstrong\u003eFour-Range Switching\u003c\/strong\u003e: Like other 9000-series units, it automatically shifts between four current ranges (starting at the 150 μA scale) to maintain 0.02% accuracy across the entire spectrum.\u003c\/p\u003e\n\u003ctable style=\"height: 482.8px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 15.6026%; height: 47.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 84.0377%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eENCT9008SD5V300mA\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=\"width: 15.6026%; height: 47.6px;\"\u003e\u003cem\u003ePower\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 84.0377%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eAC110V or AC220V±10%, single phase, 50\/60Hz, 800W\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=\"width: 15.6026%; height: 47.6px;\"\u003e\u003cem\u003eChannel Numbers\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 84.0377%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003e8 channels\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 10px;\"\u003e\n\u003ctd style=\"width: 15.6026%; height: 10px;\"\u003e\n\u003cp\u003e\u003cem\u003eVoltage Features\u003c\/em\u003e\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width: 84.0377%; height: 10px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eVoltage Range: -5 ~ 5V\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eMinimal discharge voltage: -5 V\u003c\/li\u003e\n\u003cli\u003eAccuracy: ± 0.02% of F.S.\u003c\/li\u003e\n\u003cli\u003eStability: ± 0.01% 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: 262.8px;\"\u003e\n\u003ctd style=\"width: 15.6026%; height: 262.8px;\"\u003e\u003cem\u003eCurrent Features\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 84.0377%; height: 262.8px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eOutput Range: \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e           Range 1: 0-0.3 mA\u003c\/p\u003e\n\u003cp\u003e           Range 2: 0.3-3 mA\u003c\/p\u003e\n\u003cp\u003e           Range 3: 3-30 mA\u003c\/p\u003e\n\u003cp\u003e           Range 4: 30-300 mA\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAccuracy: ± 0.02% of F.S.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCV Cut-Off Current: ≥ 0.3μA\u003c\/li\u003e\n\u003cli\u003eStability: ± 0.01% 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: 67.2px;\"\u003e\n\u003ctd style=\"width: 15.6026%; height: 67.2px;\"\u003e\u003ci\u003eTime\u003c\/i\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 84.0377%; height: 67.2px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eCurrent Response Time: ≤2 ms\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eMin.
