Replacing the battery today is a costly affair as prices have skyrocketed and are in no rush to return. But starting a car is getting more difficult every day and the service has to be replaced inexorably. How to independently and correctly make a decision without overpaying, but without often slandering honest people? Details are on the AvtoVzglyad portal.
“Oiling”, but won’t start? And if you “light up”? Then he drives and does not “sneeze”. Khan battery. This is what self-diagnosis of a car battery looks like, applied in every yard or garage cooperative from Kaliningrad to Vladivostok. At a car service, they can add professional expertise: with the help of a charging plug, they “jump” the battery and analyze its consumption. If the “voltage” has dropped below 7 volts – writing waste, the engine will no longer start. However, between black – in the trash – and white – the engine starts – there is a “grey zone” that is rarely talked about. Knowledge is power, and in our case money too.
Before you wave your card at the register, there are a number of actions you need to perform, each of which can cancel a trip to the store. Let’s inspect the contacts and connections first and make sure there are no oxides and other debris on them. If so, it’s worth cleaning as the contact patch could cause a problem. We should not forget about other “contacts”: the most common example is the mass, the attachment to the body has long rusted and rests on one copper hair. At this rate, no battery is enough to start the engine.
The battery has been removed, it is time to inspect it. And washing: thick dirt and cracks on the case do not contribute to high-quality work. Since it has come to use the hands, it is no sin to check or even replace the “liquid” in the battery – electrolyte. It tends to boil away which is also what causes the battery failure. It’s cheap and the result is clear.
After examining the wires and the battery itself, you need to mount the system in place and connect a multimeter – a simple and inexpensive device that can answer many questions. The normal voltage for a car battery is 12.8 volts. If the device shows less than 12.4 muted, it’s worth raising the alarm. The battery is not charged. Why? Cold starts, short trips, power leakage, extra consumers. There could be many reasons, but the conclusion is the same: the battery is doomed.
To delay the implementation of this, you need to remove the battery and completely discharge it – a two-wire light bulb can handle it. Then we charge with a simple charger, which the neighbor can find, and continue to observe. If there were no more than three full discharges, the battery can still be revived. More is no more. Even a full charge via the socket does not give any result: the battery does not last, literally discharged before our eyes. Irreversible processes have already started in it, so you still have to go to the store. But already with a sense of satisfaction and full confidence in the decision.
