The car battery is on strike, time for a change? Not necessarily. If necessary, the battery can still be made usable again with a battery pulse.
The low car batteries are a major issue in modern cars. Because power consumption is high: assistance systems, seat heating, navigation systems – everything has to be supplied with electricity. The alternator provides replenishment while driving. But especially on short journeys, the journey does not take long enough to fully recharge the battery. This will damage the battery over time.
Battery Pulse: what is it actually?
Many car batteries run out after just four years. That does not have to be that way. A supposedly broken starter battery can be given a new freshness with the help of a battery pulse. The battery pulse, also known as a desulfator, is supposed to give batteries that were believed dead to new life. This is a small device that is connected to the plus and minus poles of the battery. It emits current impulses at certain intervals that are supposed to make the battery functional again. Important: The battery pulser is not a battery charger, it only ensures that the battery can be charged again.
Almost all common car batteries are lead batteries. They consist of lead plates in a sulfuric acid mixture. When the battery is discharged, sulphate crystals form, which normally dissolves again when the battery is charged. However, if the battery is not fully charged over a longer period of time, the crystals will be deposited on the plates (sulfation). The result: the battery’s charge capacity drops. At some point, the sulfation has progressed so far that the battery can no longer be charged. Usually, at this point the car battery is “pronounced dead” and needs to be replaced. However, you can sometimes reverse the sulfation with the battery pulse. The voltage peaks of the battery pulse should break up the sulfate crystals and reverse the sulfation. The battery pulser can either be connected when the battery is already on strike, but it can also be permanently attached to the battery as a precaution so that sulphate deposits do not arise in the first place. Even high-quality chargers sometimes have a desulfation program. However, they are only suitable for short-term use.
What Are the Advantages of The Battery Pulse?
• Protect the environment: Every broken car battery generates a few kilos of toxic waste. The longer the battery can be used, the better it is for the environment.
• Get full power: If the pulser is permanently connected to the battery, no deposits will form in the first place. So the battery always delivers full power.
• Save money: A new car battery costs between 50 and 200 euros, depending on the type. If you have them installed in the workshop, you pay another 30 to 50 euros more. For comparison: a battery pulse costs around 50 euros.
How Else Can You Take Care of The Battery?
• Charge regularly: Short journeys in particular can affect the battery. It should therefore be recharged regularly with a charger. The same applies if the car is parked for a longer period of time: Connecting a charger to maintain the charge prevents starting problems. Car battery chargers under test
• Keep the battery clean: If the poles of the battery are dirty, leakage currents occur which can lead to discharge.
• Keep an eye on the voltage: With a battery tester or retrofittable voltage displays for the cockpit , you can check the battery voltage. If it falls below 12.4 volts, it is high time to recharge.
