Modern vehicles in and around Chicago run on 12 volt electrical systems. 12 volts is enough to get the job done for Chicago drivers without having so much power that there is danger of electrocution. But today's vehicles have more electrical components and do-dads than ever before. This really strains your electrical system, making it hard for the battery to keep up. Think about it: electric seats, seat heaters, power locks windows and sun roofs. And then us Illinois drivers have all the power outlets for our cell phones, computers and DVD players.

We also have navigation systems and powerful stereos. Plus there are all the engine and transmission computers, traction control, stability control, anti-lock brakes, sensors and on and on. Even the security system is running off the battery while the car is turned off.

Fortunately, battery technology has given Chicago drivers resilient batteries that are able to meet these strenuous requirements. But the fact is, batteries just wear out over time. Eventually, every battery gets to the point where it cannot hold enough of a charge to start your vehicle. Sometimes batteries need to be replaced because they have just worn out. Or, in other cases, they have developed a leak which makes it even more important to get it replaced.

Special safety precautions are taken when working with batteries at Tuffy Chicago (Diversey Pkwy) in Chicago, Illinois. These precautions also apply to anyone who is poking around the battery. Batteries contain sulfuric acid that can damage your eyes and burn your skin, so safety glasses and rubber gloves are a must for any Chicago resident working with their battery. Be careful to not spill acid on your clothes or the vehicle's paint. Of course, avoid short circuiting the battery as well.

Sometimes there is quite a price range in Chicago auto part stores for batteries that will work in a particular car. Think of it as "good," "better" and "best." More expensive batteries have a longer warranty and are guaranteed to last longer. As with most things, paying a little more up front saves in the long run for Chicago drivers.
