Ever had one of those dreaded moments where your car won’t start no matter how many times you turn the key? Chances are, your battery’s the culprit.
But don’t fret! We’ve got your back with this simple, no-fuss guide. From spotting the signs of a failing battery to replacing it like a pro, we’ll help you get back on the road in no time. So let’s dive right in!
How does a Car Battery work?
Think of your car battery as the heart of your vehicle’s electrical system. It powers essential components like the lights, audio system, starter motor, and fuel pump.
The battery works through a chemical process. When electrons flow from the cathode to the anode, it stores energy in the form of chemical potential. When you start your car or use electrical systems, the electrons flow in the opposite direction, converting that stored energy into electricity to power your car.
Usually found in the engine compartment, the battery supplies energy when the engine is off or when the electrical demand exceeds what the alternator can provide.
When does your Car Battery need to be replaced?
Now that you understand how your battery works, spotting potential issues becomes easier. By recognising the warning signs early, you can change your car battery before it leaves you stranded. Look out for:
-
Sluggish engine start
If your engine starts slowly, it’s a dead giveaway (pun intended) that your battery is taking its last breath. When batteries age, they lose their ability to generate current, causing the engine starter to receive less power.
-
The check engine light pops up
A lit-up ‘Check Engine’ light doesn’t always indicate an engine problem. However, it could be your car telling you about a dead battery.
-
Dim headlights and electrical problems
When your battery is losing its power, it results in dim headlights, dim interior lights and the overall electrical system of your car doesn’t work properly.
-
Your battery is corroded
If both terminals of your car battery turn brown, white or blue/green, it’s time to get a new battery. Because a corroded battery prevents your car from starting.
-
Swollen or bloated battery Case
If you see that the battery case seems enlarged or bloated, the battery is likely defective and has to be replaced right away.
How to know when your Car Battery is dead?
Car batteries have varying lifespans based on different factors such as quality, driving conditions, climate, maintenance, and how they were initially installed and stored. For instance, a battery that frequently experiences cold temperatures generally has a shorter lifespan compared to one kept in warmer climates.
However, on average, a car battery can last longer for about three to five years. With proper care and car maintenance, your car battery can last up to 6, or 7 years. Read your car’s manual to know the exact lifespan of your car battery.
Easy steps to change your Car Battery
If your battery is dead and needs replacing, here’s how you can install your new battery and be back on the road in no time!
Step 1: Safety comes first
Before getting started make sure you’re wearing gloves and glasses. Also, make sure your car is in ‘Park’ or ‘Neutral’ and keys are removed from the ignition.
Step 2: Disconnect old battery
Start with removing the negative ‘-’ terminal first and then the positive ‘+’. First, you need to open the nuts and bolts anticlockwise to remove the black cable connected to the negative terminal and the red cable connected to the positive terminal.
Gently lift both cables off the battery terminal, ensuring they don’t touch any metal surfaces.
Step 3: Clean the battery tray
Clean the battery tray with a baking soda and water solution to get rid of any corrosion or leftovers before installing a new battery. Rinse with fresh water and let it dry completely.
After removing an old battery you have to dispose of it very carefully at your nearest recycling centre or you can also give it to an auto parts store that accepts used batteries.
Step 4: Install a new car battery
First of all, you have to place the battery in the tray making sure it’s well seated. While installing a new battery you have to reverse step 3 and first connect the positive terminal with a red cable.
Use a spanner or pliers to tighten the nut or bolt on the positive terminal. Make sure it’s snug, but not too tight.
How to maintain your new Car Battery?
The key to extending your car battery’s lifespan is regular care. Follow these simple tips to keep your battery performing at its best for longer:
-
Regular cleaning
Periodically clean the battery terminals to avoid the build-up of corrosive material.
-
Add water carefully
If you see that the electrolyte levels have dropped (the plates will be exposed), refill them with distilled water. It’s better to use a funnel or sports bottle while adding water to the battery.
-
Avoid short trips
Short trips prevent your car’s battery from fully charging. Maintain your battery’s health by driving it regularly and for longer periods.
-
Use a battery maintainer
If you won’t be using your car for an extended period, connect it to a battery maintainer e.g. Battery tender or maintainer. This device will keep your battery fully charged at a safe level.
-
Keep it warm
The cold weather is harmful to your battery’s health. That’s why it’s advised to keep your battery warm by engine or a battery heater. When your battery is warmed enough it consumes relatively less power.
