The opening voltage of the lead-acid battery is to measure the voltage value measured in the case where the battery is not accessed, simply saying that the opening voltage of the mobile phone battery is the voltage value, non-working state measured in a state where the phone is not loaded. When the circuit is not currently flowing, the electricity poor is different between the battery positive and negative electrical poles, when the battery open circuit is measured, the battery should be in a steady state, the battery charge, discharge, or fill the distilled water, and then stand back and then measured. The battery open voltage can be measured by the voltage file of the multimeter, and the red and black tablets of the multimeter are positively connected to the battery, and the negative electrode is connected.1. Opening voltage: The electric potential of the battery is 2.045V. Therefore, the rated voltage is 2.0V. The relationship between the open circuit voltage and the electrolyte density of the battery can be calculated by:
Open circuit voltage = 1.850 + 0.917 (p-liquid-P water) or
Open circuit voltage = p liquid +0.84
The p liquid in the formula is the density of the electrolyte, and the pensity of P water is water.
2, self-discharge: lead battery is no matter whether it works. There is a discharge phenomenon inside, and white consumes electricity. The reason for self-discharge is also impurities in the inside of the battery.
