Sealed lead acid battery, also known as a lead-acid battery, is the oldest type of rechargeable battery and one of the most common energy storage devices. These batteries were invented in 1859 by French physicist Gaston Planté, and they are still used in a variety of applications. Most people are accustomed to using them in vehicles, where they have the ability to provide high currents for cranking power.

Q8: How can you tell if a battery is good or bad?
A8: You should first check the battery for defects such as a broken circuit, a short, or a broken container. If an outward problem is not apparent, then you will have to check the battery's capacity using known measuring techniques to ascertain the problem.
Q9: Why "zero voltage" might happen?
A9: Zero voltage means there is a broken circuit. There could be several reasons for a zero voltage state.
1.There could be a broken electrode column
2.Welding defects of the partition
3.Welding defects of the terminal
