A car battery warranty usually lasts 24 months or a set mileage limit. It covers manufacturing defects and common issues. If the battery fails during the warranty, you can get a free replacement. After that, a pro-rated fee may apply. Review the specific conditions and coverage details before purchase to understand your rights. Key coverage … Read more

The car battery charging system uses an alternator to turn mechanical energy from the engine into electrical energy. The alternator has a stationary part called the stator and a spinning part called the rotor. As the engine runs, these parts work together to generate electricity, which recharges the battery while the car is moving. The … Read more

The alternator charges the car battery during driving. At highway speeds, it generates enough energy to keep the battery charged and powers onboard electronics like air conditioning and lights. When the vehicle is stationary or moving slowly, these systems can drain the battery, which slows the charging process. Idling affects the charging process significantly. When … Read more

A car battery cannot truly charge and discharge at the same time. Charging occurs when the alternator supplies current, while discharging happens when the battery powers car electronics. Techniques like trickle charging help manage small loads, but excess simultaneous charging can cause overheating and damage the battery. While the battery charges, it also supports the … Read more

To determine the age of a car battery, find it under the hood. Look for a sticker showing the manufacturing date, usually formatted as “MM/YY”. For example, “03/15” means the battery was made in March 2015. Knowing the battery’s age aids in evaluating its life, maintenance needs, and planning for replacement. Another way to assess … Read more

To recharge your car battery, first, disconnect the negative terminal. Then, connect the charger: positive to positive and negative to negative.

To charge a dead car battery, connect the battery charger to the vehicle’s battery terminals—positive to positive and negative to negative. Make sure to turn off the charger before plugging it into a power outlet. Set the correct charging settings and monitor the process. Always follow safety precautions to avoid mistakes. If using a battery … Read more

Car batteries can be the same size but have different Cold Cranking Amps (CCA) because of differing designs and materials. Higher CCA improves engine starting in cold weather. Batteries with higher CCA often contain more lead plates. Always select a battery that matches the designated group size for optimal fit and performance. Batteries of the … Read more
