- Incorrect Battery Type: Using the wrong type of battery for your vehicle can lead to poor performance, premature failure, or even damage to your electrical system.
- Overtightening the Battery Terminals: Overtightening the battery terminals can cause them to crack or break, leading to potential electrical issues.
- Reversing the Polarity: Connecting the positive and negative terminals incorrectly can cause serious damage to your vehicle's electrical system and potentially create a hazardous situation.
