Product Details

opzs solar batteries belong to free maintenance rechargeable battery, Because of the advantages of the maintenance free battery, the consumption of the electrolyte is very small, and there is no need to supplement the distilled water during the service life. It also has the characteristics of high temperature resistance, shock resistance, small volume, small self discharge. The service life is generally two times that of the ordinary battery. There are two kinds of maintenance free batteries in the market: the first one is to add electrolyte at the time of purchase, and then do not need to maintain (add the supplement) in the use. The other is that the battery itself has been well sealed and sealed when it is out of the factory, so the user can't add any liquid at all.

Electrochemical reaction in electrodes


1. The electrochemical reaction of the valve controlled lead-acid battery is shown as follows. Charging is to recharge the external DC power supply on the battery, so that the power can be converted into chemical energy to store. Discharge is the release of electrical energy from the battery to drive the external device.


2. When the VRLA battery charge reaches its peak, the charging current is only used to decompose the water in the electrolyte. At this time, the positive electrode generates oxygen, the negative pole generates hydrogen, and the gas will overflow from the battery, resulting in the reduction of electrolyte and the need to add water regularly.


3. On the other hand, at the end of charging or overcharging, the charging energy is used to decompose water. The oxygen produced by the positive electrode reacts with the sponge like lead of the negative electrode, so that a part of the anode is not in full state, and the negative pole hydrogen is produced.
