⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems.
•Wear gloves and goggles to protect from acid and corrosion.

Symptoms

•Engine cranks slowly or takes longer than usual to start
•Dashboard warning lights, particularly the battery or check engine light, are illuminated
•Electrical accessories operate weakly or intermittently
•Corrosion visible on battery terminals
•Unusual, clicking noise when turning the ignition
•Battery age is over three to five years, depending on the brand

Diagnostic Steps

1
Inspect the battery terminals for corrosion and ensure they are tight.
2
Check the age of the battery; look for a sticker or engraving indicating the manufacture date.
3
Test the battery voltage using a multimeter; a healthy battery should show around 12.6 volts or higher when not under load.
4
Perform a load test on the battery with a load tester to check its ability to hold voltage under load.
5
Inspect the alternator's performance to ensure it's charging the battery correctly.
6
Check for any parasitic drain that could be discharging the battery when the vehicle is off.
