This sludge or mud can short out the plates of a cell and when it happens, it could kill the battery. The flakes form into a sludge that settles at the bottom of the battery case. Under normal conditions, a battery will already show signs of aging on or after its third year.īecause of the regular contraction and expansion of the plates during the discharge and charge cycle, the active positive materials of the plates flake off causing the battery to “age” or lose some of its capacity. Batteries are assigned a lifespan of from three to five years. The normal cause of death of a battery is age. You know that batteries die, but do you know why? There are a number of reasons why batteries die, but the sure sign of death is when the battery plates’ active material is no longer able to deliver a discharge current which could be due to the following: Your battery may not yet be completely dead, but it’s getting there. These signs and symptoms may just be warning signals. When the “Check Engine Light” icon on your dashboard lights up, this could be another sign of a weak or failing battery. “Check Engine Light” warning signal is lit A parasitic drain can render your battery dead.ĥ. Other causes of a battery drain are bad diodes of the alternator and grounded relay switches. This could be caused by lights (trunk lights, signal lights, headlights, hood lights or globe box lights) that do not turn off when you close the car door. A recurring starting problem is a sign that your battery is being drained during the night by a parasitic draw.Ī parasitic draw or drain is a continuous drain on a battery’s power even when the engine is shut off. But, two days after it happens again, the car refuses to start. One morning, your engine starts with one click, the next morning it takes several attempts to crank it, the next day everything is fine again. It might be crying out already for a replacement. If aside from an engine that does not turn over, you also can’t turn on your lights, you better have your battery check. When the alternator is not in operation, the battery powers your electrical system. The engine won’t crank and start and the lights are offĪ situation where your engine refuses to crank and start and the lights (headlights, dome lights, etc) won’t turn on is a clear indication that your battery is in trouble. There could be other causes of such a plight such as lack of fuel or a worn starter, but 98% of the time, the culprit is a weak or flat battery.ģ. This is a case where your engine cranks when you turn the key, but refuses to run.

The battery leads can also work loose, or the case may crack through being bumped about.There are times when the engine will start, but this is after several attempts of cranking it. Make sure that the battery is not loose in its mounting, or This is a fire hazard in any circuit, but becomes an even greater one in the battery-starter circuit, which has around 300 amps flowing through it. Be sure to examine it also.Īnd solenoid for loose connections, which can cause sparking. Some cars have another earth lead between theĪnd the body or chassis.

There must be a bare-metal contact for proper earthing. Remove these deposits also from the battery carrier or any other metal parts - they are very corrosive.ĭoes not cure the trouble, examine the earth lead - particularly where it is attached to the body or

The mating surfaces of both connectors and battery posts must be free from dirt and corrosion.Īny green or white powdery deposits must be removed, and the metal surfaces beneath brightened. The Ford type has a flat cable connector bolted to a flat battery post. The clamp is secured by a bolt the cup by a screw into the top of the post. The most common types of connector are a clamp thatĪround the battery post, or a cup that fits over it. Unless they are in good condition, the current cannot flow through them properly - and sometimes not at all. If you suspect the circuit, look first at the battery-terminal connections.

If, however, the battery is fully charged, the trouble is probably in theĮither way, lack of power is preventing theįrom working - though there may be just enough
