What's Involved?
Slow engine crank:
If your car takes noticeably longer to crank when starting, it could indicate a weak battery.
Dimming lights:
When idling, if your headlights noticeably dim, this can be a sign of battery issues.
Clicking sounds:
Hearing clicking noises when attempting to start the car is often a sign of a failing battery.
Corrosion on terminals:
Visible build-up of white or green corrosion around the battery terminals indicates potential problems.
Swollen battery case:
A bulging, misshapen battery case is a serious sign that needs immediate attention.
Old age:
Even if your battery isn't showing symptoms, if it's more than 3-4 years old, it's a good idea to have it checked and potentially replaced.

What's Involved?
Visual inspection:
Checking for physical damage, leaks, swelling, or signs of corrosion on the battery case and terminals.
Terminal cleaning:
Removing corrosion from the battery terminals using a wire brush or specialized cleaning solution to ensure a good electrical connection.
Battery voltage test:
Using a battery tester to measure the battery's voltage under load to assess its health and ability to start the engine.
Cable inspection:
Checking the battery cables for fraying, damage, or loose connections.
Electrolyte level check (if applicable):
For non-sealed batteries, checking the electrolyte fluid level and adding distilled water if necessary.
Tightening connections:
Ensuring all battery terminal connections are securely tightened.
