Although battery clamps are small, improper handling can cause serious consequences, including battery explosions and equipment damage. This article summarizes five common misconceptions to help you avoid these risks.

Taboo 1: Reverse Polarity
Consequence: Reversing the positive and negative poles can cause a battery short circuit, instantly generating thousands of amperes and potentially causing an explosion.
Correct Operation: Clamps are marked with "+" and "-" polarity; be sure to check the battery markings before connecting.
Taboo 2: Operating Without Disconnecting Power
Consequence: Plugging or unplugging a clamp while power is on can cause arcing, burning contacts, or even fire.
Correct Operation: Turn off the power to the device before connecting or disconnecting the clamp.
Taboo 3: Using Corrosive Cleaners
Consequence: Cleaners like gasoline and alcohol can damage the insulation layer of the clamp, increasing the risk of electrical leakage.
Correct Operation: Wipe the contacts with a dry cloth or a small amount of specialized electronics cleaner. Taboo 4: Prolonged Exposure to Humidity
Consequences: Moisture infiltration can cause contact oxidation, increased contact resistance, and increased heat generation.
Correct Operation: Store in a dry, well-ventilated area and avoid use outdoors in the rain.
Taboo 5: Forcing a Damaged Clip
Consequences: Deformed contacts may lead to poor contact and device failure.
Correct Operation: Replace the clip immediately if cracks or deformation are detected; do not continue to use it for cheap.
