Car Battery Replacement In Johnson City, TN

CCA or Cold Cranking Amps are a measure of how long a battery can deliver power at 0 degrees Fahrenheit for 30 seconds and not drop below 7.2 volts

RC stands for "Reserve Capacity" and is the number of seconds a battery at 80 degrees Fahrenheit takes to discharge 25 amps until the volts drop below 10.5amps

If you continually need a jump start, it could be a few problems with your charging system.

1. You may need a new battery (The mechanics at our Johnson City, TN shop can check your battery for free)
2. Your alternator may not be operating. If your alternator is not working properly, it will not charge the battery.
3. You may be missing a belt that helps to turn the alternator. Or the belt is slipping. This is often called the serpentine belt.
4. The pulley for your serpentine belt may be stuck, or missing. If the belt is missing, your alternator will not spin and charge the battery.
5. Your battery cables could be loose. A tech will test your battery and also test for tightness of the wiring bolts to your battery.
6. Your start may be be bad. This will always cause a battery to run out of power, especially when the vehicle is parked.
7. You may have faulty wiring or an electrical issue with your car. A technician will test all electrical components if your battery and alternator are working.

• Wet Cell Battery: A wet cell battery is the most common type of battery. It comes in two styles: Serviceable and Maintenance Free. This type of battery is in the majority of vehicles. The cells are filled with electrolyte.
• Absorbed Glass Matt (AGM): Glass matt is placed in between the plates inside the battery. These batteries can produce more power in a smaller battery and are better if you are not using the vehicle every day they hold their charge over time without use.
• GEL Cell Batteries: these are similar to the AGM battery because of the electrolyte which is suspended. The absorbed glass matt (AGM) is still considered a wet cell battery. This battery doesn’t do well if it is overcharged. Make sure to charge with the proper charger. These are very deep cycle and do better in hot applications.
• Deep Cycle Battery: This is a battery designed to have less quick delivery and is designed to have better energy delivery over a longer period of time. Deep Cycle batteries are made for marine and golf cart applications.
