Accumulated corrosion on the battery terminals. In this article we advise you to do to avoid cracking. And how to clean the starter battery, traction or any acid-lead battery of the sulfate accumulated outside. We will still always recommend that a qualified and experienced technician carry out these tasks, which can become dangerous. You can contact Renobat.

The appearance of cracks in the housing or battery case can cause sulfuric acid leakage from the Outside.

Clean Battery Terminals

This situation can occur when:

Are received blows or by Excessive vibration Due to a bad mechanical clamping between the battery and the base that keeps it attached to the car frame.

Excessive vibration also causes the contacts between the battery terminals and the connection terminals of the wires that attach them to the terminals to become loose.

Therefore, a false contact is produced which will cause failures in the operation of the equipment and electrical devices of the car. In addition to the possibility that dangerous sparks may arise.

This in the long run is detrimental to your company as it increases the risk of accidents and reduces operationality.

a battery with cracks in the housing or enclosure constitutes a potential explosion hazard.

Battery cracked-Battery terminal cleaningA battery with cracks in the casing must be replaced. It takes a lot of risk to work that way.

In this case the only possible solution is to replace it with a new or used one, which is in good condition and with Load. But never scratched.

however, to avoid this type of breakdown, it is advisable to periodically check the screws and tighten their anchorage to the frame if they have loosened.

Also avoid hitting the battery with blunt objects. For example: A metal Hammer when adjusting the connection terminals of the cables to the terminals, because it can also Cause cracks in the housing or box.

With the time of use of the car it is normal for the battery to accumulate dust and dirt, and also to show traces of dry sulfate on the outside caused by the accidental spillage of the Electrolyte.

This usually occurs because the plugs of the vessels or cells located at the top or battery cover have not been kept tightly closed. O the electrolyte level has been exceeded when you last filled your glasses with distilled water.

Sometimes we can find corrosion formation in the base and metal parts that hold the battery to the frame of the car also caused by the accidental spillage of the electrolyte.

Tips for removing dirt and corrosion from batteries:

  • Battery Terminal cleaningCheck that all the plugs located on the top of the battery for each vessel or cell are tightly closed to prevent the electrolyte from spilling out from the outside.

  • Clean the outside of the battery with a non-metallic bristle brush to remove any traces of sulfate from the electrolyte that has been inadvertently spilled before. and is already dry (whitish appearance).

  • Once the sulfate has been removed, pass through the outside of the battery a cloth impregnated in a solution composed of 125 grams of sodium carbonate (or sodium bicarbonate), dissolved in a liter of tap water. Remove until all surfaces are completely clean. Then dry it all with another clean cloth or absorbent paper.

  • Remove any corrosion from the metal base that holds the battery to the car frame, or any other metal parts adjacent to it, with a metal bristle Brush.

  • Then pass a cloth impregnated in the aforementioned carbonate or bicarbonate solution and then dry with a clean cloth or absorbent paper.

  • It is advisable to paint the oxidized metal parts with some type of anti-corrosive paint after cleaning them.

To perform any of these operations it is necessary to have qualified and experienced personnel.

Renobat is available to make a free review of the battery just contact us or contract our maintenance services or battery optimization. So our technicians can do these tasks at the same time.
