Johnny's Auto & Marine Electric Service

Johnny's Auto & Marine Electric service means quality work.

Today's auto electric systems are getting more intricate and are stressing the limits of current technology but they are basically the same design as 30 years ago

Before replacing any battery due to a failure, have the battery and the car's electrical system tested for proper functioning.  Replacing a dead battery only to have another few weeks later due to a weak alternator or a parasitic drain on the system is not only frustrating but can be expensive and dangerous as well. 

An average battery should last 3-5 years in average climates but those in high heat or extreme cold areas may last only 2-3 years.  The replacement battery should always have the same or higher CCA rating (cold cranking amps) as the original and be of the same or compatible "group size" to fit the battery tray and cable connections. 

Your car's electrical system should be completely checked and tested every two years or whenever serviced for any type of driveability problem.  Many problems associated with day-to-day driveability are caused by voltage variations and must be the first step in troubleshooting any problem.  This is due to the use of computerized controls in most cars these days and even quite minor voltage changes can alter the controls.
