Loose Battery Terminals – Repair & Servicing in Hamilton

About battery terminals: 

Every car battery will have a negative and positive terminal. Battery terminals are usually made of lead, which offers high conductivity and low electrical resistance. 

These terminals are the first point of contact between the battery and your car’s electrical system. This means that if they become loose or fail, electricity may not be able to reach important parts of your vehicle. Sometimes, the terminals can become loose from the cables. This can cause not enough electricity to enter the rest of your car, causing symptoms similar to a flat battery.

Other common causes of terminal failure include corrosion, rust, or physical damage to the terminal.
What causes battery corrosion?


Symptoms of loose battery terminals:

Car will not start – If the cable has completely come loose from the terminal, the battery will not be able to send power to your car’s ignition upon startup. This will prevent your car from starting.

Battery dies quickly – If the battery terminals have a poor connection, the rest of your charging system will not be able to feed power back into the battery. This can cause the battery to run flat quickly.

Battery warning light – If your car’s charging system is struggling to transfer power to your car battery and the rest of your car, the battery light may appear on your dash. This is your car’s way of warning you that there is insufficient power.
