A dead battery is a frustrating and inconvenient automotive problem. If you find that the battery is usually dead when you start the car in the morning, it could be because you need a new battery. But where do you start and how do you determine the correct battery for your vehicle? Read on for some helpful tips.
Get a new car battery
One option is to call your local garage. They will select and install a battery that is most appropriate for your car and your budget. There are several factors to consider when choosing a battery and they include your car’s electrical system and the size of the car battery pack your vehicle needs.
The other option is to obtain and repair a new battery yourself. It is not difficult to do and could save you a lot of money. You just need to know how to choose the right battery.
Different types of car battery
There are two basic types of batteries which are called wet cell batteries and VRLA batteries. It is important that you choose the correct type for your car, as well as the correct group size.
- Wet cell car batteries
They are also sometimes called flooded batteries and are a category of lead-acid batteries. Inside these types of batteries, there is a liquid electrolyte so that they can be recharged. This is done when the engine is running. If you have this battery in your car, you will need to check the dilute acid level. The water in the solution can evaporate and will need to be refilled. Distilled water must be used and you must get the correct ratio of water to acid for the battery to function properly. One version of a wet cell battery is a semi-solid electrolyte battery which you can see described as a sealed battery. These do not have to be recharged.
There are two versions of the wet cell battery. The first is a SLI (start, light, ignition) battery that will start your car with a short burst of power and also powers the lights and ignition. However, once the car has started, the alternator provides the power it needs to keep running. Most cars have this type of battery.
The second version is a deep cycle battery that can also be called a marine battery. These will last longer and can supply power for a longer period. They can be downloaded repeatedly without breaking the bank.
This means valve regulated lead-acid battery. They are sealed and do not vent gas (hydrogen) so they are perfect for small spaces that have ventilation and are easy to store. They are also very safe.
You have the option of a gel cell battery or an AGM battery. As the name suggests, the gel cell battery contains a gel electrolyte rather than a liquid one. They are very resistant, very resistant to heat and are not damaged by shocks. They work like a normal wet cell battery, but are sealed so they don’t evaporate. You can also choose an absorbed glass mat battery where the electrolyte is held on glass mats. They work the same as wet cell batteries, but battery acid cannot spill.
Different sizes of car battery
In addition to the type of battery, you must also choose the correct size. Car battery sizes are described in terms of battery group size. So what does the size of the battery pack mean? It is an industry standard that describes the height, width, and length of the battery. It also describes the location of the positive and negative posts on the battery, which is called polarity. Because the batteries are standard size, it is easier for vehicle manufacturers to design the engine compartments.
Battery pack size is a simple industry standard, making it easier for you to find the right battery when you need to replace it. You do not need to pull out your tape measure to find out the size of your battery pack, it will be printed on the battery label and indicated in your owner’s manual. You can also use a car battery pack size chart that is available online. The battery group is specific to the year, make and model of your car. The most common battery pack sizes are 24, 24F, 25, 34, 35, 51, 51R, 52, 58, 58R, 59, and 65.
Manufacturers tend to favor a particular battery group size. Many General Motors vehicles in the US have side post batteries. These don’t …
