In one sentence, describe what the following article is about: with water and baking soda. First, identify the positive side of the battery by finding the red cap. Always disconnect the negative side first. Turn the bolt connecting the wires to the negative terminal counterclockwise and lift the wire up. Do the same for the positive side, making sure you don't touch the 2 wires to any metal parts of the car. Then make a 1:1 mixture of baking soda and water. Dip a hard-bristle brush into the solution and scrub both battery terminals.  Wipe the terminals down with a wet rag when you're done. Remember to reconnect the battery properly when you’re finished. Always reconnect the positive terminal first. Rust and corrosion on the battery terminals inhibits its performance and lifespan. After you’ve cleaned the battery terminals, protect them from further corrosion with terminal spray. Hold the can 4 inches (10 cm) from the terminal and spray until the connection is coated. Then spray the other terminal.  Spray after the battery is reconnected to protect the terminal and connection point from corrosion. Terminal spray is available from auto parts stores. Only use products that are designed for use on battery terminals. Excessive vibration can damage the battery over time. The hold-down bar keeps the battery stable and prevents vibration damage. Test your battery hold-down by opening the hood and shaking the battery. If the battery moves, the hold-down is too loose. Locate the bolts connecting the hold-down to the battery. They're usually along the top of the battery, where the hold-down bar stretches across. Use a socket wrench and turn the bolts clockwise to tighten them.  There are different types of hold-downs on different cars. The most common type is a bar stretching across the top of the battery. This is easy to locate. Some cars use a hold-down pad instead. These are along the base of the battery. Look here if you don't see a bar across the top of the battery.  If the hold-down is damaged in any way, replace it right away. New parts are available at auto parts stores. If you live in a cold climate or winter is on its way, a battery heater can prevent your battery from dying in the cold. These are basically jackets that fit over the battery and keep it warm. Get a battery warmer from your auto parts store and follow the installation instructions for the product.  There are 2 main types of battery warmers. The first is insulated fabric that wraps around the battery. These are cheaper but less effective. The second is a rubber wrapping that inflates when you plug it in. This provides more insulation for the battery. For some warmers, you have to remove the battery completely to cover it. On others, the warmer wraps around the battery while it’s still installed. Follow the instructions on whichever product you use. Unscrew the vent caps on top of the battery and look inside each cell with a flashlight. The fluid should cover the battery plates. If it doesn’t, the level is too low. Pour in distilled water until the water covers the battery plates and reaches the bottom of the cell refill holes.  Wipe off any excess fluid with a rag before replacing the vent caps. Wipe away from the cells to prevent getting dirt inside your battery. You may have to use a flathead screwdriver to pop the vent caps off. Remember to put them back on securely. Only use distilled water, not tap water. Tap water has dissolved minerals that will affect the battery’s performance. Check the battery fluid levels every time you do an oil change, or roughly every 6 months. When it does come time to change the battery, always get a new one. Look on the side of the battery for the manufacture date. Find one that was manufactured within the last month for the best battery performance.  Getting a new battery is important because they deteriorate over time. A battery more than 1 month old will probably last a shorter time than a brand new one. Avoid buying a used, discount battery. These will almost certainly not last very long.
Summary: Clean the battery terminals Coat the battery terminals in terminal spray to prevent corrosion. Tighten the hold-down to prevent the battery from rattling around. Wrap the battery in a battery heater to prevent damage from the cold. Check the battery fluid level and add distilled water if it’s low. Buy a battery that’s less than a month old when you replace yours.

In one sentence, describe what the following article is about: If you want to swim to stay fit, you first must find a pool that is convenient to you. Ideally, you want to find an indoor pool so you can continue your swimming regimen year round.  Find out what classes are available at the pool, as well as the cost to use the pool. These fees can add up, so ask if you can purchase a monthly or yearly membership that will give you unlimited access to the pool for less money. Carefully inspect the pool and facilities. Ask staff about pool maintenance and make sure everything is kept clean and sanitary. One of the best parts about swimming to stay fit is that you typically don't need to invest in a lot of equipment to get started. However, you will need at least one swimsuit that is comfortable and functional for swimming.  If you're wearing a women's swimsuit, choose a one piece and move around in it to make sure it fits well and the straps won't slide off while you're swimming. Keep in mind that swimsuits stretch when they are wet, so be cautious about selecting a suit that is loose or stretchy. Polyester swimsuits hold up better in chlorinated water than suits made from other materials. If you're wearing men's swimming trunks, choose those that cling rather than board shorts or other loose, flappy shorts. You may want to cover more of your body for modesty reasons. Most pools allow full wetsuits that cover your arms and legs. Talk to the staff at the pool where you plan to swim so you can better understand your options. At a minimum, you'll probably want to buy a pair of goggles to protect your eyes from the chlorine. If you have longer hair, you also may want to get a swim cap to keep your hair from getting in your way while you're swimming. Chlorine can also change or fade your hair color, so you may wish to wear a cap to protect your color.  Some pools may provide towels, but you may want to invest in a more super-absorbent towel for quick hops out of the pool for a water or bathroom break. Flippers or fins, hand paddles, and kick boards are swimming equipment used in perfecting your stroke or increasing your speed. Many pools loan these out for free or for a small rental charge. If you find you use these items regularly in your swimming routines, however, you may eventually want to buy your own. If you have a hard time keeping water out of your nose, consider buying nose plugs. If you've never taken formal swimming lessons before, or if you last took lessons as a small child, you might want to take some lessons before you start swimming for fitness.   Working with a swim coach for your first few sessions will help you perfect your form and correct any bad habits you may have developed over the years. You also need to focus on your breathing technique. Incorrect breathing will sap your energy level and make your stroke less effective. Before you sign up for lessons, consider the type of training you are most interested in. Types of swim training include stroke development, training to improve starts and turns, sprinting, distance training, and open-water swimming. If you find yourself getting stressed out or feeling pressured or intimidated by more serious swimmers, take a moment to remind yourself of your reasons for swimming. Focus on your own goals, and try not to compare yourself to other swimmers you may encounter. What’s most important is that you get what you want out of your swimming experience.
Summary:
Scout out swimming locations. Buy appropriate swimwear. Get other equipment if needed. Learn proper stroke techniques. Enjoy yourself.
