Internal resistance or impedance measurements are a common method to assume the condition of a lead-acid battery. The readings could lead to predictions about the state-of-charge (SoC) and/or state-of-health (SoH) condition of a battery without the necessity of performing a full charge/discharge cycle. In practice, the readings
There are two general types of lead-acid batteries: closed and sealed designs. In closed lead-acid batteries, the electrolyte consists of water-diluted sulphuric acid. These batteries have no gas-tight seal. Due to the electrochemical potentials, water splits into hydrogen and oxygen in a closed lead-acid battery.

THE STORY: I have several portable 200Watt speaker systems that I use for our outdoor events. They come loaded with a 12V 7A standard acid-lead batteries. When brand new, I can use such a speaker and almost max output for 3-4 hours. One year has passed and now their use time is down to 50min to maybe 1h. YES, I did by new 12V 7A batteries, but

Recently, I was asked to help a customer with a battery circuit in which he wanted to put 10 12V batteries in series to increase the A/H rating by ten times. I knew that this was not the correct method to do what he wanted to do. In short, batteries in series increase the source voltage to the circuit, while batteries in parallel increase available current. If you look at

The charging voltage for the valve regulated lead acid battery should not be in excess of the gassing voltage, which is 2.4~2.5V/cell. The gassing voltage varies with temperature, and is decreased as the temperature is increased. Its temperature coefficient is –5.0mV/°C/cell.
The lead acid battery maintains a strong foothold as being rugged and reliable at a cost that is lower than most other chemistries. The global market of lead acid is still growing but other systems are making inroads. Lead acid works best for standby applications that require few deep-discharge cycles and the starter battery fits this duty well.
