  • Know how a Lead Acid Car Battery Works

    Have you ever wondered how does a lead acid car battery works, then wonder no more #MidasPower At Randburg Midas we do not only supply new batteries, we also have a great range of battery chargers. Lead oxide plates interacting with sulfuric acid in a car battery is what creates the electrical current used by the car’s starter and electrical system. That’s the basic and simple description. In order to gain a better understanding of how a car battery works, you need a little more than just the bare basics. The following paragraphs will describe some construction features of a lead acid twelve volt car battery and then give a more complete description of the chemical processes your battery undergoes during the charge and discharge cycles. Construction Your car’s battery has a specialized hard plastic shell which contains the sulfuric acid electrolyte and the lead oxide plates. The top cover is made from a slightly thicker and heavier piece of plastic. From this top plate is a heavy lead oxide suspension matrix which supports the lead oxide plates and the separator plates. If the separator plates weaken or fail, the battery can short out internally. The material most often used for separator construction these days is rubber. In a lead acid car battery, the lead oxide plates alternate positive and negative, or cathode and anode. The greater the surface area of the plates, the more current the lead acid battery will be capable of supplying. Typical methods of increasing the surface area of the lead oxide plates and thus increasing output is by intentionally pitting the plates and drilling holes in them. Other chemicals and metals are added to the lead oxide of the plates in order to stabilize them and to slow down their rate of degradation under extreme usage. Many manufacturers use a red lead and sulfuric acid dilute paste that is pressed into the holes in the plates. The use of this mixture greatly enhances electron transfer as well as multiplies the usable surface area of the plates. The Chemical Process In a lead acid car battery, electrical current is created during the discharge cycle as the lead oxide plates absorb sulfate from the diluted sulfuric acid solution. The amount of current produced depends on how much sulfate the electrolyte is able to give up during discharge. When the battery is charged, the process is reversed. Current is pushed through the positive…

  • Cleaning Your 4×4 after Mudding

    Cleaning your 4×4 after mudding is not fun or an easy task, but if you follow these tips it will be done in no time #Carwash Randburg Midas has an impressive range of cleaning products, and if we don’t have what you are looking for, we will get it especially for you. Mudding is awesome! Man and machine against Mother Nature. It’s fun, it’s dirty, but it is a chore to clean your rig. Mud gets everywhere and as soon as you think you’ve got it all there’s more. Here is some advice for getting your rig clean after she’s all muddy. The sooner, the better. Mud is different everywhere. In some regions it’s thin and watery; in others it’s thick like wet concrete. No matter what type of mud your rig is covered in the sooner you wash it off, the easier it will come off. This is simple common sense, but for a few drivers out there this goes against natural instinct. Driving around town with a truck covered in mud is like a badge of honor. But, soon as that mud dries it literally can become like concrete in your undercarriage. My advice is as soon as you’re done mudding go wash your truck. Use high pressure. Cleaning your rig is chore, speed up the process and use some muscle with high pressure. There are two options to consider when it comes to washing with high pressure. Pressure Washer: This is the best choice if you have the space (yard or drive way) and the money to invest. Don’t forget, all that mud has to go somewhere – after you’re done cleaning your 4×4 you’ll most likely need to clean your driveway. Be cautious, higher PSI and paint don’t play nice together. You can also buy a U-Shaped attachment for your pressure washer to easier reach the undercarriage. Car Wash: A DIY car wash is great because the pressure is higher than using a standard hose and you don’t have to clean up! Another bonus is many car washers have a warm water rinse which makes mud removal easier. Don’t forget under the hood. The engine bay is an area of much debate on how to clean. Depending on the age of your vehicle there is going to be anywhere from a little to a lot of precious electronics under there – which you DO NOT want soaking…
