Car Battery Tester - More Info

All drivers at some time in their driving career have had to suffer with a flat or low charged battery. In the old days of the 1970s, a car battery tester was only found in a mechanics workshop, nowadays however, the car battery tester is found in most home garages. So, what exactly does it do? This device, when clamped to the positive and negative terminals of your car battery, will tell you the condition of your car’s battery. If the reading is low and you have just been driving, you can be sure that within the next few days your car’s battery is going to die. If it happens to die somewhere out on the highway and then you’re going to have to pay a great deal of money to get your car towed to the nearest service station for repair. Checking your battery at home, allows to you to prepare for the inevitable. 
     
The car battery tester has evolved over the years, once a cumbersome machine that required two people to move it around; it is now a hand held device which can deliver readings in seconds. The Chinese made XIELI car battery tester is one such hand-held device. The operator connects it to the positive and negative terminals and then presses the “check” button, within seconds, on the small display; one can read the battery’s condition which appears in three different colors, red, blue and green, for easy reading. After using the car battery tester, it may be a good idea to test whether your car’s battery is actually holding its charge. Turn the vehicle’s lights on for ten minutes without the engine running. Once ten minutes have passed, start the engine. If the vehicle soon starts, then it is safe to say your battery is in good condition. If, however, your car doesn’t start soon, then perhaps it is time to call the garage and order a new battery.
     
When checking your car battery experts advise wearing protective clothing, like gloves, eye glasses and rubber boots. Removing all kind of jewelry is a must as jewelry is a good conductor of electricity and one spark caused by you bracelet or some other trinket, may make you battery explode and you an X-ray. Another in important fact to remember is not to disconnect the positive battery terminal when the engine is running and this too could cause a spark and explosion. Finding the right car battery tester on the market is difficult, however asking your local mechanic which one he recommends would ensure your purchase the right one. The XIELI from China seems to work very well however.
