Understanding Car Batteries
The Basics of Car Batteries
A car battery is a device that provides electrical energy to a vehicle. It is typically made up of six cells, each with lead plates that are immersed in a solution of sulfuric acid and distilled water called electrolyte. When the battery is charged, a chemical reaction occurs in each cell, which converts lead plates and electrolyte into lead sulfate and water. This process produces electrical energy that powers the car’s electrical system, such as the starter, lights, and radio.
Common Battery Problems
Car batteries can often fail due to various reasons, including overcharging, undercharging, sulfation, or a damaged or leaking cell. Overcharging can cause the battery’s plates to corrode and its electrolyte to boil. Undercharging, on the other hand, can cause sulfation, a buildup of lead sulfate crystals that can inhibit the battery’s ability to hold a charge. A damaged or leaking cell can cause electrolyte to leak out and weaken the battery’s capacity.
When it comes to the voltage of a car battery when not running, it should typically be between 12.6 and 12.8 volts. A voltage of less than 12.6 volts can indicate that the battery is not fully charged, while a voltage of more than 12.8 volts can indicate that the battery is overcharging or overheating. It’s important to check the battery voltage regularly, especially if you’re experiencing any issues with starting the car.
Regular maintenance of your car battery can help prolong its life and improve its performance. This includes checking the battery connections, cleaning any corrosion, and topping up the electrolyte levels if necessary. It’s also important to avoid overcharging and undercharging the battery and to keep it in a cool, dry place when the vehicle is not in use.
- Tip: If you’re planning on storing your car for an extended period of time, you may want to consider disconnecting the battery or using a battery tender to maintain the battery’s charge.
Idle Battery Voltage
