Test of AkkuFresh® by the Kindai University
Kindai University, formerly known in English as Kinki University, is one of Japan’s largest and most popular private, comprehensive research universities. It is highly regarded for its commitment to “practical learning” and its groundbreaking scientific research.
Comparison of voltage change between lithium-ion batteries with and without AkkuFresh® (Tested under the collaboration with Kinki University).
Tested batteries: Lithium-ion batteries for mobile phones made by the manufacturer K, which were charged and discharged more than 200 times and used for more than 1 year.
[Rated voltage: 3.6V. Charging capacity: 550 mAh.Charging time: 2.5 hours]
Test conditions:
● Continuous discharge with 14 ohms resistance.
● Ambient temperature: 25 ohms.
● Ambient humidity: 55%
● Tester: Manufactured by NEC.
The feature of lithium-ion battery for mobile phone is to keep going on with the same voltage for a certain time and to fall the power down sudden and sharply upon the charged electric power be used up.
The test result clearly indicates the battery with AkkuFresh® put on lasts much longer as shown by the D4 blue colored line in the graph.
Blue line = Battery with AkkuFresh®
Red line = Battery without AkkuFresh®
X = Voltage Y = Time (min.)
The Kindai University has clearly proved the effectiveness of AkkuFresh® Next Generation™ – the original nano-tech battery life foil technology.
*Similar test down by the Osaka University and Kobe University
The effect and performance of AkkuFresh® Next Generation™ depend on several factors:
Type of device (mobile phone/notebook/camera / etc.), brand, model, type of battery, age, status (total amount of charging-discharging cycles), external temperature, environmental conditions, and cellular network.
