BU-403: Charging Lead Acid

The lead acid battery uses the constant current constant voltage (CCCV) charge method.

6 FAQs about [Principle of Constant Temperature Lead-Acid Battery]

How does operating temperature affect the life of a lead-acid battery?

Operating temperature of the battery has a profound effect on operating characteristics and the life of a lead-acid battery. Discharge capacity is increased at higher temperatures and decreased at lower temperatures. At higher temperatures, the fraction of theoretical capacity delivered during discharge increases.

What are the properties of lead acid batteries?

One of the most important properties of lead–acid batteries is the capacity or the amount of energy stored in a battery (Ah). This is an important property for batteries used in stationary applications, for example, in photovoltaic systems as well as for automotive applications as the main power supply.

How do thermal events affect lead-acid batteries?

Thermal events in lead-acid batteries during their operation play an important role; they affect not only the reaction rate of ongoing electrochemical reactions, but also the rate of discharge and self-discharge, length of service life and, in critical cases, can even cause a fatal failure of the battery, known as “thermal runaway.”

What are the performance factors of lead-acid batteries?

Another important performance factor for lead–acid batteries is self-discharge, a gradual reduction in the state of charge of a battery during storage or standby. The self-discharge takes place because of the tendency of battery reactions to proceed toward the discharged state, in the direction of exothermic change or toward the equilibrium.

What factors limit the life of a lead-acid battery?

The factors that limit the life of a lead–acid battery and result in ultimate failure can be quite complex. The dominance of one over another is bound up with the design of the battery, its materials of construction, the quality of the build and the conditions of use.

How long does a lead acid battery last?

The end of life is usually considered when the battery capacity drops to 80% of the initial value. For most lead–acid batteries, the capacity drops to 80% between 300 and 500 cycles. Lead–acid battery cycle life is a complex function of battery depth of discharge, temperature, average state of charge, cycle frequency, charging methods, and time.
