r******g

The electrode materials of HoldPeak are carefully delivered to the factory in the form of black powder that is almost indistinguishable. The product can improve the stability of the electrocircuit effectively

w******q

Once the cell assembly is complete, HoldPeak must be put through at least one precisely controlled charge/discharge cycle to activate the working materials. The product can withstand the fluctuations of large voltage

e******e

The anodes and cathodes materials of HoldPeak are dealt with by our technical staff under complete procedures. These procedures include mixing, coating, compressing, drying, and slitting. It, processed in dust-free workshops, contains no impurities

v******q

The processes of HoldPeak involve blending the raw materials, specialized grinding of the raw materials, inert atmosphere firing of the raw materials, and a final grind of the finished product. Its ultra capacitance can be up to 330,000uF

j******l

HoldPeak has undergone a series of tests before its shipping. These tests include cell-cycle life, impedance measurements, and over-discharging. The product is extremely miniaturized, occupying little space

p******m

The product has good quality and excellent performance. It has the advantages of low loss and high overload capability
