⚡️ When the electrical current becomes unstable, charging and power delivery become more difficult. This can damage the vehicle’s electrical system and affect engine starting, potentially causing sparks during operation. In some cases, a loose terminal can cause nearby plastic parts to overheat and melt, leading to sparking and gradual corrosion or loss of lead at the battery terminal.
If any of these issues occur, the battery should be inspected immediately by a professional technician for safety.
🪫 Loose battery terminals can be caused by several factors, such as stripped terminal bolt threads that prevent proper tightening, deterioration of the lead terminal sleeve, damaged or broken lead terminals on the battery itself, or normal vehicle vibrations during driving that may cause the terminal to shift and loosen over time.
Therefore, always remember to regularly check your battery condition before use—and choose FB Battery, a premium-quality battery that gives you confidence on every journey.
