How To Keep The Battery Alive Without Removal?
When a car battery is plugged in, the car always eats the energy emitting from the battery. Yes, even if you keep your car parked, the car soaks the power inside the battery. If that happens, the battery should run out in a week of regular use, right?
The main work of the car battery is igniting the engine. That doesn’t eat much power. But you run all the other accessories like headlights, music system, heater, etc., these also run on the battery. So, it’s not obsolete to think that the battery will run out in a week. But would it?
The answer is no. Just like any inverter, the car engine juices up the battery. When the RPM hits at least 1000, the battery starts recharging itself. So, that means, when you drive your car, you’re technically adding more life to the battery.
It’s understandable that battery dries out when the car ignites or the accessories run, but why does it drain while the car is parked? The answer is very easy. Think about TV in standby mode. It doesn’t take much electricity but still eats a little bit off the line. In the case of cars, the same thing happens.
So, if you ignite a car and keep the engine and the accessories running without driving it, it’s like watching TV or running the ac. That’s when more electricity is consumed. But when the car is parked, it’s in standby.

So, How Can You Keep The Battery Okay Then?
It’s easy but repetitive. All you have to do is start the car every now and then and run it for at least 5-10 minutes in neutral and reach at least 1000 RPM. That way, you can fill up the lost charge when your car was idling.
But it’s not only about the repetition but also about the fuel. When you ignite the car and accelerate putting it in neutral, it’ll consume some fuel. So, to make this happen, you need to waste some fuel for preserving the battery. So, it’s not considered the ideal way although the battery remains in the best possible shape.
How To Keep The Battery Alive With Removal?
This process is cost-free but you need a special skill to make it happen. All you have to do is remove the battery from the car and keep it in someplace safe.
Someplace safe means keeping it far from your loved ones, especially the children. The battery has a toxic substance inside. That is quite harmful to your skin. So, keep it somewhere children don’t have the access.
Now, you know when to keep your battery, let’s concentrate on how. The idea of removal has two reasons. One, to keep the battery unplugged and ensure the preservation of power and two, keeping it in a dry and moderate temperature place.
A little bit of moisture can cause the battery to lose the optimal temperature for staying alive. What you can do is clean it every once in a while with a dry piece of cloth.
Do not keep the battery directly on the surface. Always keep a floor mat that soaks moisture to keep it dry and nice. This method is more acceptable because you don’t have to waste any money to store the battery and you can keep the battery alive for a brisk 4 to 6 months. Not bad, huh?
