- Q: How to repair the battery?
- Charge the battery at constant voltage. It is the beginning of the time, using 0.1C ~ 0.25C current charge, to 16.2V later, by reducing the current method to maintain the charging voltage, until the charge current drops to 0.03C when the stop charging.
- Q: How is the capacity of the battery defined?
- The capacity of the battery unit is AH (safety) is the product of current and time.
- Q: What are the technical parameters of the battery?
- Usually the capacity of the power supply is expressed by kV · A or kW. However, as a power supply VRLA battery, the use of security (A · h) that its capacity is more accurate.
- Q: How to determine the battery is good or bad?
- Instrument test: the general use of battery discharge tester, the test instrument two positive and negative clamp were holding the battery positive and negative electrodes, press the test button to observe the test instrument instructions.
- Q: What battery does the van use?
- The most obvious feature of lead-acid batteries is the top of the plastic cover can be unscrewed, there are ventilation holes above. These fillers are used to fill pure water, check the electrolyte and the use of exhaust gas. In theory, lead-acid batteries need to check the density of each electrolyte and the level of liquid, if there is a need to add distilled water. But with the upgrading of battery manufacturing technology, lead-acid battery development for the lead-acid maintenance-free batteries and colloidal maintenance-free batteries, lead-acid batteries do not need to add electrolyte or distilled water. Mainly the use of positive electrode to produce oxygen can be absorbed in the negative oxygen cycle, to prevent water reduction. Lead-acid water batteries are mostly used in tractors, tricycles, car start, etc., and maintenance-free lead-acid battery wider range of applications, including uninterruptible power supply, electric vehicle power, electric bicycle batteries. Lead-acid batteries according to the application needs to be divided into constant current discharge (such as uninterruptible power supply) and instantaneous discharge (such as car to start the battery).
- Q: What are the advantages of maintenance-free batteries?
- The advantage of a maintenance-free battery is that the service life is twice as long as the dry battery! And in the use of the process without maintenance! The voltage is also relatively stable.
- Q: What is the meaning of the battery above 12v65Ah?
- 12V represents the rated voltage. 65Ah indicates that the battery capacity (ie 1 ampere current can be used for 65 hours).
- Q: What is a maintenanceable battery?
- This is relative to a maintenance-free battery. Maintenance of the battery needs to be supplemented with electrolyte to ensure work, while maintenance-free is not required.
- Q: How does battery activation work?
- If you are talking about dry batteries, that is, to add sulfuric acid can use the battery (commonly known as water bottles), then it is because the long-term storage so that a high degree of oxidation of the negative board, plus acid will be a high temperature, Low, you can add acid in the pool after the addition of a small current for a long time to charge, you can solve. Generally with 0.05C charge to 3 times can be.
- Q: Lead-acid battery how to maintain?
- Open the rubber cap, exposing the exhaust raft, you can see the battery inside, some of the battery exhaust cutting can be unscrewed.
