What are the factors that affect the internal resistance of the battery during the use of the battery
What are the factors that affect the internal resistance of the battery during the operation of the battery? Let's take a look at the editor below
1. Temperature: The battery is very sensitive to temperature. The high temperature of 102 degrees Fahrenheit has little effect on the internal resistance of the battery (less than 2%). Low temperature will have some influence on internal resistance, but when the electrolyte temperature is not lower than 65 degrees Fahrenheit, the influence of temperature battery internal resistance is very small;
2. Charging and discharging: In the same environment, using various methods to discharge 20% of the battery's power will only have a very small impact on the internal resistance of the battery. In a practical test, 20% of the battery power was discharged at a lower rate, and it was observed that the internal resistance of the battery only changed by less than 3%;
3. : Because the negative electrode is in an incompletely charged state for a long time, the local active material becomes irreversible lead sulfide, which increases the resistance of the paste;
4. Drying: As long as VRLA (valve-controlled Lead-acid batteries) will be in this situation, and finally the conduction path will be completely disconnected from the adjacent grid.
