Practical Information

What should be done if the battery voltage is below 12.4V under open circuit condition? 
The battery should be connected to supply charge with 1/20 amperes of the Nominal Capacity.

What is the reason if the voltage of battery connected to vehicle is above 14.2V or 14.5V? 
Vehicle generator regulator is defective.

What is the reason if the voltage of battery connected to vehicle cannot reach 13 Volts?
Vehicle generator regulator or charge dynamo is defective.

What is the reason if the voltage of battery connected to vehicle is above 13.5V? 
One of the diodes of the charge dynamo has burst.

What is the reason if the voltage is above 13 Volts when the vehicle is idle? 
Vehicle generator regulator is defective.

What should we do if the indicator (lamp) is not green color in the new battery?
The ball of the indicator may have got stuck. The battery should be shaken to the right and left.

What is the reason if the label on the battery is shriveled and the colors of the screen-painting have been distorted?
The battery has been overcharged. The charge dynamo should be checked.

What is the reason if the voltage of one of the batteries is low, in vehicles using two batteries? 
One of the batteries is drawing 12 V current.

What should be done to obtain 12 V current in vehicles using two batteries? 
A converter must be placed in the circuit and current should be drawn from both batteries.

What is the reason if increasing values are observed for acid densities, from the negative cell to the positive cell?
The frame cable has become oxidized or the battery cannot obtain enough frame.

What is the reason if the acid color is not clear and is brown? 
The battery may have been overcharged, may have expired, the active substance in the plaques have drained down and mixed in the electrolyte.

What is the reason if the battery is not working in the morning but is working during the day?
The acid densities and voltage of the battery should be checked, if there is no problem with the battery, then the injector, starter motor and the heater plugs, if diesel, of the vehicle must be examined.

What would happen to the battery if the vehicle is used for a few times each month? 
The battery shall undergo sulfation due to standby loss and the vehicle shall become inoperable. Therefore the vehicle should be operated for at least 10 minutes, once every 15 days during summer and once a week during winter.

Can normal be used in commercial taxis? 
12V - 72 Ampere TAXI BATTERY must absolutely be used.

Which battery should be used in buses? 
Batteries produces specifically for buses should must be used.

What is the reason if in diesel vehicles, the vehicle is not operating even if acid density and voltage values are normal? 
The heating plugs of the diesel vehicle may be defective. The plugs should be checked.

What should be taken into account when mounting and removing the battery to and from the vehicle.
When removing the battery from the vehicle, first the negative cable end should be removed, and when mounting, first the positive cable end should be connected.

Should the acid be poured if the battery is not used?
Battery acid should never be poured.
