Why Battery Health Actually Matters
Because it’s the heart of your car
✅ No battery = no start
✅ No start = no work, no shops, no nothing
But not all dead batteries are really dead
Some just need a jump
Some need the bin
Let’s break it down
Signs Your Battery Just Needs A Jump
If it’s acting tired
But not totally gone
✅ You left your lights on overnight
✅ Car clicks or cranks slowly but doesn’t start
✅ You’ve not driven it in a while
What to do:
✔ Jump start it with cables or a portable battery
✔ Let it run for 20–30 minutes or drive around
✔ If it starts fine next time — you’re probably good
Signs You Need A New Battery
This is when it’s game over for your battery
✅ It dies again right after a jump
✅ It’s more than 3–5 years old
✅ The engine won’t crank at all
✅ You hear fast clicking — or nothing
✅ Dashboard lights flicker or dim weirdly
✅ You see corrosion around the battery terminals
Basically
If it keeps letting you down
Stop begging it to live
How To Do A Simple Battery Health Check
You don’t need a mechanic
Just some basic checks
1. Check The Age
Most batteries last 3–5 years
Look for a little sticker on top — usually shows the install date
2. Look At The Terminals
✅ Are they clean
✅ Or covered in white crusty fluff
If they’re dirty
✔ Disconnect the battery
✔ Clean the terminals with baking soda and water
✔ Reconnect and try again
3. Try A Voltmeter
✅ If you’ve got one, check the voltage
✔ 12.6V = perfect
✔ 12.4V = okay
✔ Below 12.0V = replace soon
✔ Below 11.8V = bin it
4. How Does It Start?
✅ If it starts fine once jumped but dies again overnight
That’s a sign the battery is toast
Or something else is draining it
My Story With Battery Drama
Once had my Citroën die on a cold Monday morning
Jumped it
Worked
Died again next day
I kept jumping it for three days like a stubborn ex
Finally got a new battery — fixed it instantly
Lesson: stop dragging it out — just replace the thing
Quick Tips To Avoid Battery Hassles
☑ Drive your car regularly — short trips drain batteries
☑ Keep terminals clean
☑ If your car’s parked for long — use a trickle charger
☑ Don’t ignore slow starts — it won’t fix itself
☑ Replace it before winter if it’s nearly done — cold kills batteries fast

At least 20–30 minutes — or better, take it for a proper drive.
