Cars

Did you ever go to jumpstart your car, and notice that you can barely see your battery underneath all the gunk? This ‘gunk’ is actually battery corrosion, which is formed by acid condensation. Since this is formed by acid, a basic chemical solution will do the cleaning trick. Battery acid is actually very easy to clean away with a common household item- baking soda! But still, precautions must be followed. This article will inform you step by step how to clean the battery while keeping safe.

First, you will need to gather supplies for this project. Most of these items you may already have in your home.
Safety glasses or goggles
Box of baking soda
Adjustable pliers with insulated handles
Screwdrivers with insulated handles
A small, stiff-bristled brush (an old toothbrush will work just fine!)
Assorted small open-end and box wrenches
Small metal or plastic scraper
Special battery tools, including a cable puller and cable terminal cleaning brushes
A turkey baster or small funnel
All-purpose household cleaner in a spray bottle
Sponges or clean cloths
A source of ample clean water such as a garden hose or a large bucket and sponge
Rubber gloves for protecting your hands

There are a few safety tips to keep in mind when getting ready to clean the battery. First of all, you safety glasses and gloves must be worn to protect your eyes and skin from sulfuric acid that can linger in the corrosion deposits. Also, this material can eat away at your car’s paint, so keep it away from that as well.

Because the amount of dirt and corrosion on batteries may differ from one another, battery cleaning will vary, so some of the steps below may or may not need to be performed. Sometimes, to thoroughly remove severe corrosion and dirt, you may even need to remove the battery from the vehicle.

First, scrape off any white or greenish corrosion deposits with the stiff-bristled brush or small metal or plastic scraper. Next, use the solution of baking soda mixed with water, approximately one heaping tablespoon to each pint of water. Carefully apply it to the outside of the battery and its cable connections with the turkey baster or small funnel. Then, you can use your brush to work the baking soda solution into the heavily corroded areas. If you find that the cable clamps or terminals are badly corroded at the battery, you can disconnect them for easier cleaning. For this, you may need to use pliers, assorted wrenches and a small battery cable puller to disconnect them. You should disconnect the negative first, followed by the positive.

Then, use your battery cable scrapers or brush to remove the corrosion from the terminals, battery posts and hold down clamps and brackets. Flush these parts with your baking soda solution to rid them of any trace of corrosion. After this, wash the outside of the battery, the cable ends and the hold down parts with a liquid cleaner in a spray bottle. After that, use a sponge or rag to get off any remaining dirt or grease. After everything is clean, dry off the battery and all its parts with a dry rag or cloth.

The final step is just reinstalling any part that was removed and tightening everything so it is secure. Reconnect the battery, positive cable first. You’re done! You’re battery is now safe and clean.

For most of the lifetime of automobiles, propulsion has been provided by the gasoline or diesel powered internal combustion type of engine. There have been brief flirtations with steam, electricity, and vehicles that could use a variety of fuels, but most of these have fallen by the wayside as the gasoline engine pushed billions of vehicles down the road.

However, this single-minded dependence on petroleum-based fuels, and lubricants too, has placed the planet on the edge of a new future…a future without petroleum or, at best, with limited petroleum resources. Government, business, and designers have combined efforts to come up with some sort of solution to at least part of the problem of maintaining our present way of life with the fact of decreasing petroleum supplies.

In previous incarnations of the personal vehicle, steam did not prove suitable for simple, daily operations, and electricity was limited by the speed with which battery charges dissipated, the length of time required for recharging, and the need to redesign and create an infrastructure for electric cars.

The recent solution has been the hybrid vehicle. The hybrid car combines gasoline engine technology, already fairly highly advanced, with a battery/electric motor combination, which also uses technology that is well known.

WHAT A HYBRID VEHICLE DOES

The gasoline powered engine can provide higher, sustained speeds for long periods of time and recharge the battery as needed by means of a generator (more on this in a moment). The battery/electric motor can provide the power to begin moving the hybrid vehicle, continue moving it at lower speeds and can power systems such as lights, radio, and air conditioner when the vehicle is at a stop. This simple step of having the vehicle turn the engine off during idle times such as at stop signs, stop lights, drive-thrus, and stop-and-go traffic can result in quite a fuel savings by itself.

The forward movement of the vehicle itself can help store power in the battery by turning the electric generator. One interesting aspect of this is that the electric generator which recharges the battery when turning in one direction is also the electric motor which draws power from the battery to move the car at lower speeds. This, in its most basic form, is done by reversing the spin of the central rotor of the generator/motor. This use of the same device to power the car and recharge the battery also allows for a unique feature – regenerative braking.

REGENERATIVE BRAKING IN A HYBRID VEHICLE

Regenerative braking is very simple in concept and turns a frequent and unavoidable expense into an asset in more than one way. In an ordinary vehicle, brake pads or shoes press against a rotor or drum to slow and stop the vehicle. This generates a lot of heat. Brake pads, shoes, rotors, and drums wear out due to the friction and heat and have to be replaced regularly. This can be expensive.

Stop-and-go city driving, tends to be the place where a large amount of braking occurs, so this is where most of the wear on brake parts occurs as well. With a regenerative braking system, such as that in the Toyota Prius hybrid, most braking will actually be provided by the electric motor itself at slower speeds. As you apply the brake, the electric motor which was propelling the car now reverses itself and becomes a generator recharging the battery as you slow and stop. The reversed motor creates torque which slows the vehicle and brings it to a stop, so the regular brake parts receive a lot less wear and need to be replaced less often.

FUEL ECONOMY AND “PLAYING THE LIGHTS” WITH A HYBRID VEHICLE

Add into the mix that stop-and-go city driving burns a lot of fuel. In a gasoline or diesel powered automobile, it takes much larger amounts of fuel to start a vehicle from a stop than to keep it moving. It requires less fuel to pick your speed back up when you have slowed down than to come to a complete stop and have to start from that point. Some truck drivers (and trucks burn a lot of fuel), have been taught to view events ahead and take their foot off the accelerator if they feel they may have to stop at a light that is red or “stale” green, or if there is congestion ahead which will slow them down anyway. This is called “playing the lights” and can result in significant fuel savings in any vehicle. A hybrid vehicle with regenerative braking is going to be saving wear and tear on brake parts, and taking it a little easier on the “go pedal” will help save even more in fuel costs if the driver is “playing the lights”.

A hybrid vehicle commonly improves fuel economy by using the electric motor to start the vehicle moving and by letting the battery take care of times that the car would normally be idling. A well designed hybrid car also sometimes allows the electric motor to assist the gasoline engine as well, thus adding to the fuel economy of a hybrid vehicle over a standard petroleum fuel car.

NOT ALL HYBRIDS ARE CREATED EQUAL

There are hybrid SUV’s and trucks, but these will not get the fuel economy of a smaller, lighter hybrid vehicle such as the Toyota Prius. Just to give an idea of the range, among hybrid cars, according to the federal government’s Fuel Economy website at http://www.fueleconomy.gov/feg/hybrid_sbs.shtml , the 2006 Honda Accord got an average of 28 MPG, while the Honda Insight got an average of 56 MPG, and the Toyota Prius got an average of 55 MPG. To illustrate how the difference in model can make a difference in fuel economy even among hybrid vehicles, hardly any SUV listed on the government’s website got over 34 MPG combined, and neither of the two hybrid trucks listed on my visit to the website, averaged over 20 MPG combined city and highway.

NOTE: I recently bought a Toyota Prius, and have been averaging almost exactly 55 MPG. I went on a trip, of over 2,000 miles, and 55 MPG was the fuel average for almost the entire trip. However, to emphasize how driving habits affect fuel economy, for over 1700 miles, I usually drove between 60 and 64 miles per hour on the highway, but during the last leg of my trip, I was in a hurry to get home and drove at 70 miles per hour. Driving at that speed cut my fuel economy down to under 50 MPG for that last portion of my trip.

OK, youve finally gotten through the front end part of buying your car. You have worked hard done some tough negotiating and feel like you have negotiated a good and fair deal on your car purchase and trade-in. Now its time to head into the dealers F&I (finance and insurance) department and go through the formality of signing the financing paper work on the back end of the deal.

You may have noticed a couple of terms: front end and back end. I used these terms to illustrate a point to you. From a car dealer perspective there are two distinct parts (profit centers) to each deal. The front end of the deal is the new car price, your trade in, any dealer add ons that they got you to buy with your new car, etc. All of this, most everyone is indeed familiar with. The second part of the deal, the back end, is not a place to let your guard down. The back end is the F&I department. The F&I manager is every bit as responsible for making sales numbers and profit margins as everyone else at the dealership and they are sales people NOT financial advisers and their purpose is to help maximize the profit on the deal.

Dont assume that you are going to be offered the best possible interest rate you can get by the F&I manager. Quite the opposite! Adding a point or two (or more) to your contract interest rate above what you qualify for is a serious profit maker for the dealer.

Also keep in mind that all of your hard work negotiating your deal on the front end has been by in large verbal and perhaps a handshake. True, as a result, you may have a signed buyers order or worksheet that the salesperson and or manager have signed off on, but it is in the F&I department where all of this gets put into contract form.

Stay focused. Some dealers and salespeople may even imply that in order for the deal to get approved, you have to finance through their finance department. You dont. In fact, if you have done your homework and found a better financing offer, you should take it. At the very least, you know what numbers you qualify for, and as such you should ask the car dealership to try to better what you already have.

Read the contract. Sound so basic, but most people dont. Dont just assume that everything that you negotiated with the dealership on the front end will make its way to the back end of your car deal. If youve had a long day negotiating to get the price you want, dont give it all back in the F&I department by getting lazy at this very crucial time.

Without question, the single biggest mistake car buyers make is failing to prepare. That, and setting your expectation that car buying and the negotiating process within can take at best several hours to accomplish. Know that you are going to be at the dealership for a while can help you stay energized and focused. Do your homework. Know your credit score. Get your financing pre-approved and see if the dealer can beat what you already have. Be familiar with all the areas of potential sales and profit that the dealer can potentially land. Know what extras (if any) you will and will not pay for. Make sure the contract in the F&I department reflects all the negotiations that you have worked to accomplish before hand. Then, finally, remain on your toes and dont drop your guard once in the F&I department.
