Can I Start My Car Engine with Battery Charger Attached?

The answer to this question is generally no, you should not start your car engine with a battery charger attached.

Why not?

There are a few reasons why it is not advisable to start your car engine with a battery charger attached:

• Safety hazard: When a battery charger is connected to your car’s battery, it is supplying a high amount of current. If the charger is not properly connected or if there is a short circuit, it could cause sparks or even an explosion.
• Damage to the charger: Starting your car engine can put a lot of strain on the battery charger. This can damage the charger and shorten its lifespan.
• Damage to the car’s electrical system: Starting your car engine with a battery charger attached can also damage the car’s electrical system. This is because the charger can send a surge of current through the system, which can damage sensitive components.
