What factors affect the internal resistance of Panasonic battery?
Panasonic battery plays a very important role in our life. Do you know what factors affect the internal resistance of Panasonic battery? Here is a detailed introduction:
What are the factors that affect the internal resistance of Panasonic battery in use? Let's take a look at the following
1. Temperature: Panasonic battery is very sensitive to temperature. The influence of high temperature of 102 ° f on the internal resistance of the battery is very small (less than 2%). Low temperature will have some effect on the internal resistance, but when the electrolyte temperature is not lower than 65 degrees Fahrenheit, the effect of temperature cell internal resistance is very weak.
2. Charge and discharge: in the same environment, discharge 20% of the electricity of Panasonic battery in various ways, which will only have a very small impact on the internal resistance of the battery. In the actual test, 20% of the battery power is discharged at a lower rate, and the change of the internal resistance of the battery is observed to be less than 3%;
3. Sulfuration: because the negative electrode is in the state of incomplete charge for a long time, some active materials become irreversible lead sulfide, which increases the resistance of the paste;
4. Drying up: only VRLA (valve regulated lead-acid battery) will have this kind of situation, resulting in complete disconnection of conduction path and adjacent grid.
