How to charge OPzV battery?


Theoretically, the more complete the charge of the OPzV battery, the more completes the chemical reaction between the electrolyte and the plate in the battery. When all available active substances in the battery have been converted, the battery is in a fully charged state. The key point of valve regulated lead-acid battery maintenance is to ensure the charging effect of the battery and establish an effective charging method for OPzV battery.


If the charging voltage is too high, the charging current will increase, and the generated gas is greater than the recombination efficiency, which will cause the battery water loss.


If the charging voltage is too low, the negative lead plate will be sulfated, the charging receiving capacity will be reduced, and the capacity will be attenuated. It is easy to appear a single backward OPzV battery, resulting in voltage difference and affecting the service life of the battery. What kind of charging voltage should we use?


1) Floating charge

The optimal ambient temperature of an OPzV battery is 5 ~ 30 ℃, and the battery is usually in a floating charge operation state. The room is equipped with an air conditioner to keep the ambient temperature at 20 ℃, and the floating charging voltage of the battery is 2.23v/each battery at 20 ℃. If the battery is operated under the ambient temperature below 20 ℃ for a long time, the temperature compensation coefficient is usually ± 3mV per degree centigrade. That is, when the temperature is low, the floating charge voltage is increased; when the temperature is high, the floating charge voltage is reduced.


2) Equalizing charge

When the battery runs for a long time, it is found that the voltage drop of an individual battery is too large (for example, the floating charge voltage measurement is less than 1.8V), it is necessary to adopt the method of balanced charging to adjust. At the same time, periodic equalizing charging can ensure that the OPzV battery is in a fully charged state and prolong the service life of the battery. In addition, it is suggested to charge the battery every 6 months for about 10 hours, and the average charging voltage is 2.35v/OPzV battery.


The charging method of the OPzV battery also affects the service life of the battery. By mastering the performance characteristics of the OPzV battery, users can control the charging voltage to charge the battery according to different ambient temperature conditions. The most important thing is that the maintenance and charging of the OPzV battery must be carried out by professionals. Non professionals should not touch the battery at will. Daily use must comply with the requirements ofOPzV battery and charging equipment. Protective equipment (mask, goggles, gloves, etc.) should be used when working with the OPzV battery or near the battery.
