6 Frequently Asked Questions about “Normal state of the battery plates”
What happens if a battery has a sulphated negative plate?
A battery with highly sulphated negative plates will eventually only accept a surface charge, resulting in a false positive high state of charge readings. In this condition, a battery may appear fully charged but have a very low capacity, as expressed in Amp Hour (AH) or Reserve Capacity (RC).
What is the state of charge of a car battery?
The State of Charge of an automotive battery is expressed as a Voltage (OCV) and is the force used to push the starting current known as Cold Cranking Amps (CCA) through the starter circuit to the starter motor.
What does a mud-positive plate mean on a car battery?
Muddy-positive plates are usually accompanied by negative plates that show signs of Sulfation. Since grid wires are the current collectors upon which electrical current is delivered to the starter (Cold Cranking Amps or CCA), corrosion decreases the electrical performance of the battery.
What happens if a battery is left in a discharged state?
In most cases this signifies the battery as not serviceable. Attempts to recharge batteries left in a discharged state, even at very low charge rates will lead to damage to the grid and active material interfaces and also sulphate deposits can be formed within the separators which produce dendritic shorts.
How long does a battery last?
Typically seen in a battery within 12 months service life. One cell will show a dramatically lower acid specific gravity reading than the others. The problem cell will usually boil visibly under a high discharge, all other remaining cells will show a good specific gravity reading of 1.26 or above.
What is a partial state of charge (PSoC) battery?
Moreover, modern vehicle batteries that operate in a Partial State of Charge (PSOC) condition, that seldom receive a full charge, and/or are constantly deeply cycled or micro-cycled combine with acid stratification to supercharge battery dry-out conditions and increase the likelihood of thermal run-away.
