A good tip is to scrap and clean the clamps with water and sodium bicarbonate.
A good alternator must charge between 13.5 and 14.2 volts maximum
Note: Recharge and service for damages not attributable to the manufacture of the battery are borne by the customer.
Effects of insufficient loading:
Sulfation and progressive loss of capacity.
Sulfation is not to be confused as a source of breakdowns in the Batteries, with lead sulphate forming in the plates as a natural part of the discharge process. During this process, the active material of the positive and negative plates is converted into lead sulphate which is finally crystalline and is easily reduced by the charge stream.
Sulfation or sulphated plates are referred to as a source of damage to large crystals or crusts of lead sulphate, which may be formed in the plates as a consequence of the incorrect use of the Battery.
The sulphate thus formed is very resistant to further transformations and usually adopts a greyish white color in the negative plates and milky white in the positive ones, although the color is not always a reliable criterion to appreciate the sulfation. Sometimes the color is often quite dark and the presence of the sulphate is revealed on a rough, hard surface and of sandy consistency when rubbed between the fingers. Negative plates do not give a good metallic glow when scratched with a knife
Deformation of the plates. This deformation is due to sulfate occupying more volume than active matter.
Other possible causes of sulfation:
● Carts in the workshops
● Vehicle inactivity
● Short journeys (eg islands, short distances in cities
Ways to appreciate the insufficient battery charge:
By the densimeter: Density readings give decreasing values.
By the voltmeter: The total voltage of the battery in discharge does not reach 9 volts.
Causes of exhaustion or discharge of Batteries:
● Faulty or maladjusted current regulator.
● Faults in the connection circuit.
● Faults in insulation of cables that can cause earth leakage.
● Storage without recharging (stock sulphation) – the battery must be checked periodically in its storage, if it reaches 12.2 vlts we must recharge it.
Ways to avoid overcharging and insufficient battery charge:
● Check and adjust the current regulator.
● Check the connection circuit.
● Check the electrical circuit for any leads.
● Check the Batteries in storage.
EXPLOSIONS (no guarantee)
Causes: Flames or sparks produced by the poor connection of the terminals that ignite the gases (hydrogen and oxygen) that are released during charging.
Static sparks that occur more easily when the humidity of the atmosphere is reduced.
attendance:When working with or near batteries and before approaching a flame or an object in ignition, it is necessary to be careful to blow inside the cells to expel the gases that are in its upper part.
To avoid sparks produced by removing the terminal clamps or accidental short-circuits, disconnect the charging circuit before removing the connectors from the terminals of the Battery.
To avoid static sparks, you must discharge the electricity by touching a grounded metal before working on the Battery.
Note: There is only guarantee when there is an internal short and an electrolyte level below the bridges, by statistic, this case is presented in 10%.
Iron, manganese, chlorine and chlorides, minerals
Some of the impurities mentioned above are normally found in water and exert their influence on the shorter life of the battery, hence the great importance of adding only distilled or deionized water to the electrolyte.
Intentional or accidental contamination:
Nails, coins, metallic elements, foreign bodies, brake fluids, Acpm, oils, detergents.
Maltreated Terminals (No Warranty)
No guarantee will be granted when the battery in claim
The post has been rebuilt
Terminal wear due to loose connection or bad connector.
Signs of blow or maltreatment of the terminal at the time of installation or maintenance.
Signals on the terminal have had voltage on the connectors, usually in heavy duty.
Twisted posts and posts and broken frames.
