Is your car battery draining super fast? Your car battery is the most important equipment needed in starting and driving your car. It sends power from the starter motor to the spark plugs, igniting your car fuels and giving power to other systems like lights, radio, airconditioning, etc.

And we are going to be dealing with that in this post because I can assure you your battery drains for so many reasons, even the ones we consider mundane.

So, I will list out various reasons for your battery drain.

2.Parasitic draw or drain
3.Excessive short drive
4.Corroded or loose battery cable
5.Defective alternator

HUMAN ERROR
The reason your car battery is draining could be because of some little errors on your part. In fact, most of the reasons for a battery draining is as a resultof this error. Leaving the lights on drains your battery. I know you may be guilty of that, but do that no more if you want your cary battery to last. Charging your devices drain your battery too.

PARASITIC DRAW OR DRAIN

HOW TO CHECK IF THERE’S PARASITIC BATTERY DRAIN
1.Connect a digital multimeter to the negative battery terminal of your car
2.Remove all the fuses one after the other (one at a time) while watching for changes in the multimeter reading.
3.Once the reading drops, you have found the problem!
How do you fix a parasitic drain?
1.Take off the negative battery terminal
2.Connect it between two wires
3.Start pulling the fuses
4.Turn off the switch on the overhead light
EXCESSIVE SHORT DRIVE
I know this might look outrageous but your car needs as much power as it depletes and short drives can’t ever give it that back. You can get any good battery charger to get your battery charged while it is sitting at home.
CORRODED OR LOOSE BATTERY CABLE
This won’t actually drain your battery but it will prevent it from charging as the alternator won’t recaive a good electricity.
SYMPTOMS OF LOOSE CABLE
Problem starting car
Hot ground wire cable
Headlight flicker
Low voltage car battery
HOW TO FIX A LOOSE CABLE
Tightening a loose positive or negative battery cable is quite easy and can be done in no time so far you know how to turn a wrench. Typically, there is be a nut attached to the battery terminal that you only need to turn to tighten up the connection. Yippee! You have the solution
DEFECTIVE ALTERNATOR
A car alternator is a type of electric generator used in automobiles to charge the battery and power electrical system when the engine is running.
When the alternator is bad (that is, not generating enough electricity), your car will not start. Learn how to detecta bad alternator here.
