Car Battery Diagnostics: How to Save on Costly Repairs with Simple Methods

In this article, we are going to cover the best car battery diagnostics tips without breaking the bank.

Let's talk about some diagnostic tricks about your car battery you’re gonna love!

Car battery issues are one of the most common reasons for breakdowns, accounting for about one-third of all car issues reported. Ignoring the early warning signs of a failing car battery can leave you stranded at the most inconvenient times.

Knowing how to diagnose car battery issues can empower you as a car owner and potentially

save you from hefty repair bills. In this article, we will explore five simple methods to help you identify common car battery problems before they escalate.

Visual Inspection:

Mechanic Inspecting Car Battery

Begin your diagnostics by conducting a visual inspection of the car battery. Check for signs of corrosion, which appears as a white, powdery substance on the battery terminals. Corrosion can inhibit proper electrical connections and lead to battery inefficiency. Additionally, examine the battery case for any cracks or damages. If you notice leaks or bulges, it's a clear indication of a failing battery.

Mechanic Test Voltage

Voltage Test:

To perform a voltage test, you'll need a digital multimeter. Set the meter to DC voltage and attach the red probe to the positive terminal (+) of the battery and the black probe to the negative terminal (-). A fully charged battery should read around 12.6 volts. If the voltage is significantly lower, it could indicate a weak or discharged battery. If the reading is below 12 volts, it's time to recharge or replace the battery.

Load Testing:

Load testing helps determine how well your battery holds a charge under operating conditions. While some modern battery chargers have a built-in load testing feature, you can also take your battery to an auto parts store or a mechanic for a more accurate assessment. During the load test, the battery is subjected to a simulated electrical load, and if it fails to maintain an adequate voltage, it's time for a replacement.

Car Mechanic conducts battery test

Cranking Test:

A cranking test evaluates the battery's ability to deliver power when starting the engine. Engage the ignition while observing the cranking speed and listen for any sluggish sounds. If the engine turns over slowly or you hear a clicking noise, it's likely due to a weak battery. However, if the engine cranks normally but fails to start, the issue might lie elsewhere in the vehicle's electrical system.

Electrolyte Levels Check (For Non-Sealed Batteries):

For non-sealed batteries, check the electrolyte levels in each cell. Use a hydrometer to measure the specific gravity of the electrolyte. Ensure all cell readings are consistent; variations could indicate cell deterioration. Low electrolyte levels or significant differences between cells might mean your battery is nearing the end of its life.
