NOVA Quality Control System and Cerficate:
Q1. What's the warranty of NOVA Lithium-Ion battery?
A1: 12 months if there is quality problem caused by non-artificial reason, we can give you replacement
Q2. What effect can the temperature brings to the battery performance?
A2:
Among all the environmental elements, temperature has biggest effect on the battery performance. The electrochemical reaction on electrode / electrolyte interface is connected with the temperature. The electrode / electrolyte interface is considered to the heart of the battery.
If the temperature gets lower, the reaction rate of the electrode also gets lower.
If the battery voltage keeps invariable, the discharge current becomes lower, and also the power output will reduce.
If the temperature goes up, the condition is reverse. That is, the battery's power output will increase.
Temperature will also affect the speed of the transmission of the electrolyte.
If the temperature goes up, the speed of transmission will be faster.
If the temperature goes down, the speed of transmission will be slower.
Some tests shows the temperature also affect the capacity of the same battery.
If the temperature goes up, the capacity will be higher.
If the temperature gets lower, the capacity will be decrease.
Q3. Can you customize the dimension
A3: Yes, we have complete associated equipments to create a new dimension or capacity
