How to Choose the Best Car Battery

There are some essential features to choose the best car battery.


Neither too big nor too small. And, never like this time, it is essential to take literally what you have just read.

Yes, because a battery that is too large risks not entering the space that each vehicle dedicates to it. On the other hand, a too-small one leaves a space, not necessarily pleasant from an aesthetic point of view and, in any case, will provide non-standard performance. At the height of the machine, you have purchased.

How to Choose the Best Car Battery


The average voltage, i.e., the result of the chemical reaction between the plates (both positive and negative) of the electrolyte, sulfuric acid, and water. Usually, the voltage is 2 volts for each battery cell, and, on average, the cells are 6. So the average voltage is 12 volts.

Beyond the average and what happens from a chemical point of view, the advice is to contact an auto electrician to understand which voltage is best for your car.


It’s one of the most critical factors to consider, but it’s often overlooked. Perhaps also because it is a very technical aspect but, without a shadow of a doubt, we can say that a large part of the operation of a battery depends on the amperage, which you can find with the word Ah.

It consists, in fact, of the charge necessary for the supply of one ampere of electric current for one hour.

A very important aspect, especially during the ignition phase, in this case, is called CCA (cold start amperage). Fundamental to start the engine in the best and correct way; in detail, at a temperature of 17.8 ° C below zero, the CCA is the amount of amperes the battery can support for half a minute. Why this temperature? Because it is the maximum limit for which the engine starts. Going further, it just doesn’t start.


We tell you in no uncertain terms: if you make a mistake with the battery for the car, and therefore not compatible with the car you have, you risk having wasted your money. Maybe you can easily mount it, but you will immediately understand that something is wrong in a short time: for example, the car does not provide the desired performance, or it suffers uphill.

“How do I know the battery is suitable with my vehicle?” the query comes at this stage. There are, in this sense, several answers. The most common, especially if the car is still the same, is to check the previous battery. There are labels attached with all the technical data. Just mark them on a piece of paper or take a photo, and you certainly won’t go wrong.

Or, you can read the car’s instruction booklet, where you will surely find all the necessary information. Or, again, you can go to your trusted auto electrician and get all the necessary information.

Finally, you can check the web and get detailed information about it.

Date of Production

We certainly don’t want to say that buying an outdated car battery means buying it used. But, anyway, if the date is 5 or 6 years earlier, we are almost there.

Time passes, technologies are being innovated, and, above all, if you have a new car, you certainly cannot rely on a battery that is ten years old. A glance at the production date is never a waste of time.


Do not be fooled in this regard and try to arrive at the purchase prepared. As for car batteries, there are two types of guarantees. The first concerns individuals and the second companies or subjects with a VAT number.

In the first case, the warranty lasts two years and cannot be shorter as any dealer and workshop must comply with the Consumer Code. As regards, however, a person who asks for an invoice to deduct the VAT, the guarantee will be halved, which will be for only one year.


True. Probably on some instruction booklets, you will find written that that specific battery does not need maintenance. In reality, however, that doesn’t mean you have to leave it to its fate.

But you can lean towards a battery that limits maintenance to the maximum or that is made in such a way that easy. For example, every couple of months, you need to check the electrolyte level, including its density.

Also, pay attention to the terminals: essential, especially if the battery is low, you must always keep them clean from dust and all the dirt inside the car.

Also, clean the outside of the battery and do a recharge cycle anyway if you don’t use it for a fortnight. You never know.


If you ask this question to Google, you will find the preview of the answer: 6 years. The speech, however, is much more complex. We would say 6 to 8 years at best, for example, if you do routine maintenance on both the car and the battery itself.

Or that you live in an old-fashioned Mediterranean climate, i.e., cool in winter/autumn and warm in summer. Indeed, one factor is enough to overturn this discourse.

For example, in warmer cities, the battery lasts less because the heat damages it. Or, if you live in the mountains, the effort of the climbs could shorten your life.
