One of the overlooked aspects of vehicle maintenance is making sure your battery is in tip-top shape.
Having your car’s battery unexpectedly die can really throw a monkey wrench into your day. If nobody is around to jump your vehicle or you do not have a set of jumper cables, that means calling a tow truck or triple-A for help, and in the case of inclement weather, or your work is 20 or 30 miles out of town, perhaps waiting an hour or more for help.
A car battery tester is an easy and cost-efficient method of making sure your battery is up to the challenges you place on it.
Battery testers are relatively cheap, easy to use, and a great way to avoid a tow truck or getting stuck.

How can you tell if a car battery is good or not?
There are several obvious signs of trouble for a car battery. The first, and obvious is if the battery light flashes on your dashboard. In older cars that do not have a voltage meter on the dashboard, frequently the check engine light will go off.
However, even if the voltage light doesn't flash on your dashboard, there are other indicators of a problem.
One of those indicators is if your engine cranks very slowly, or takes several tries to get it going. Assuming there is no problem with your alternator, this is a warning sign.
Another indicator is if your car needs frequent jump-starts. The occasional jump-start may okay, but if you have more to jump-start your car even once per week, there is probably a problem.
Notice your headlights seem unusually dim? Well then probably you do not have enough juice.
There are others.
A battery will typically last around 4 years, so if it's been a while, it doesn't take a rocket scientist to figure out your old battery is shot.
Another sign, indicating you definitely need a new battery is if your battery, either in cold or extremely hot weather is swelling. Swelling indicates your battery is dying from the inside out.
Another is if you open the hood of your car and there is a rotten egg smell. This likely is an indicator that your battery is leaking and leaky battery acid can destroy many parts of your vehicle, so get a complete check-up.
However, one way to tell for sure, absent all of these methods is to have a simple car battery tester. If there is not your car you can find here https://sampleproposal.org/blog/car-lease-proposal car lease proposal examples.
Most car battery testers are designed to test 12 volt car batteries, but if you also have a motorcycle, it may be a 12 volt or a 6 volt battery. So if you have both, which most people do, then buy a multi-battery automotive battery tester.
Are car battery testers accurate?
It depends on whether you have a car battery tester or whether you purchased a multi-meter tester.
Let us explain. With a multi-meter tester, which is a simpler device, you can tell whether your battery has enough voltage going through it. However, this doesn't tell whether you have enough amperage in your car to start your car or truck.
In cold weather particularly, a multimeter tester may indicate the battery has sufficient voltage, but only a car battery tester will tell you if you have sufficient amperage.
The way a car battery tester works is that it will show you the voltage, the same as a multimeter, but then you adjust the car battery tester and it puts a load onto the battery, the same as if you were actually trying to start your car.
Naturally, an automotive battery tester is more expensive than a multimeter, sometimes twice as expensive, but the accuracy of the devices is so much better.
It should be noticed that the latest and the greatest in terms of an automotive battery tester is Bluetooth. Several manufactures now make battery testers that allow you to check your battery's health via Bluetooth.
Of course, people living in Arizona or Florida will not necessarily need Bluetooth, but if you live in Minnesota where the temperature drops into the double digits, being able to test your battery in the warmth of your garage beats the heck of standing in the freezing cold.
Is 11.9 volts enough to start your car?
No. a battery showing less than 12 volts shows the battery is in discharge.
What charge does a car battery need to start?
Typically, 13.7 – 14.2V is the minimum volts necessary to start a car, but again, it also depends upon the amperage the battery delivers.
So to keep your car or truck battery in good shape, do yourself a favor and buy yourself a battery tester that will also determine the amperage load delivered by your car's battery.
