How’s your battery?

How’s Your Battery?


Take any car with an old battery that is four years old, add worn spark plugs, and a plugged fuel filter, then try and start this car on a cold winter morning. You see, a cold battery has far less power than a warm one. So if our car doesn’t start in the first, second or third rahhh, rahhh, rahhh of the starter, the battery runs out of power before the engine starts.

But most batteries will give us a warning before they fail, a warning most of us usually ignore. You should know that when your starter just clicks, or cranks your cold or hot engine very slowly, you need to have your electrical system checked. At S&S, we will load test your battery, compare the CCA (cold cranking amps) it has with what the tag says it should have. Say the test says your battery has 375 CCA, but the battery tag says it should have 650 CCA, that’s a pretty strong sign this battery is going to fail soon. But your battery worries are over if it has 672 CCA and it’s tag says it has a 650 CCA rating.

We will also test the alternator amp output at idle and at 2000 rpms. We will verify the diode pattern is good, make sure the regulator is working right and test the starter draw. We will also check for major shorts and draws. All of this is generally around $45.

Remember, a major difference between an inexpensive and a top quality battery is generally the warranty and the weight. A battery uses lead and acid to make electricity. A battery that weighs 20 pounds is likely to have a shorter life and provide less electricity than one that weighs 32 pounds. We also find the inexpensive batteries generally have less CCA’s than their tag says they should, while top quality batteries generally weigh more and have more CCA’s than their tag says they should.

So a fresh battery, a set of new spark plugs, and a new fuel filter would be a good way to insure your engine starts as fast as possible.
