All batteries age and the effects manifest themselves in diminished capacity, increased internal resistance and elevated self-discharge. A new battery (Figure 1) delivers (or should deliver) 100 percent capacity; an aged unit (Figure 2) may hold only 20 percent. In our example, the capacity loss is illustrated by placing rocks in the container.

Quicker charging times on faded batteries are noticeable especially with nickel-based batteries and in part also with lead acid, but not necessarily with Li-ion. Lower charge transfer capability that inhibits the flow of free electrons prolongs the charge time with aged Li-ion(See BU-409a: Why do Old Li-ion Batteries Take Long to Charge?)

Lead-acid batteries lose their capacity due to self-discharge during storage. Regular charging and maintenance is required, otherwise the battery will be discharged for a long time. lead-acid-battery-maintenace The amount of electrolyte decreases. For ordinary lead-acid batteries, the electrolyte level decreases, exposing the upper part of the plate to the air; for valve-regulated

In other words, the discharge capacity of a lead-acid battery exponentially decreases at high currents as shown in Figure 3 . The discharge characteristics of lead-acid batteries, which are mainly used for industrial purposes, are represented by the following Peukert''s law. t = Q p I k (1) where; Q p Discharge capacity when discharging at 1 A [Ah] I

A Guide To Lead-Acid Batteries

A Guide To Lead-Acid Batteries Structure and Operation Most lead-acid batteries are constructed with the positive electrode (the anode) made from a lead-antimony alloy with lead (IV) oxide pressed into it, although batteries designed for maximum life use a lead-calcium alloy. The negative electrode (the cathode) is made from pure lead and both electrodes are immersed in

As the battery discharges, the voltage decreases. A battery capacity chart can be used to determine the remaining capacity of the battery based on its voltage. For example, a 12V lead-acid battery that is fully charged will have a voltage of around 12.8V. As the battery discharges, the voltage will decrease. When the voltage drops to around 12.0V, the battery is

How Does Lead-Acid Batteries Work?

Lead-acid batteries are prone to a phenomenon called sulfation, which occurs when the lead plates in the battery react with the sulfuric acid electrolyte to form lead sulfate (PbSO4).
