BAIJIAN - Third party testing organization
The electrode is mainly made of lead and its oxides、 and the electrolyte is a type of battery in sulfuric acid solution. English name: Lead acid battery. In the discharge state、 the main component of the positive electrode is lead dioxide、 and the main component of the negative electrode is lead; In the charging state、 the main component of the positive and negative electrodes is lead sulfate. It is divided into exhaust type batteries and maintenance free lead-acid batteries. The battery mainly consists of a tubular positive electrode plate、 negative electrode plate、 electrolyte、 separator、 battery slot、 battery cover、 pole、 and liquid injection cover. With the upgrading of battery manufacturing technology、 lead-acid batteries have developed into lead-acid maintenance free batteries and colloidal maintenance free batteries. There is no need to add electrolyte or distilled water in the use of lead-acid batteries. The main method is to use the positive electrode to generate oxygen、 which can be absorbed by the negative electrode to achieve oxygen cycling and prevent moisture reduction. Lead acid water batteries are mostly used in tractors、 tricycles、 and car starting、 while maintenance free lead-acid batteries have a wider range of applications、 including uninterrupted power supplies、 electric vehicle power、 and electric bicycle batteries. Lead acid batteries are divided into constant current discharge (such as uninterruptible power supply) and instantaneous discharge (such as automotive starting batteries) according to application needs
