The Ultimate Guide to Buying the Right Car Battery

We all know how frustrating it can be when our car battery dies. We are in the middle of nowhere, and there is no cell phone reception or gas station in sight. If this has happened to you before, then you know that it's important to have a spare battery on hand at all times. This buying guide will give you some tips for finding the right car battery for your vehicle so that this problem never happens again.

What Are The Different Types Of Car Batteries?

The different types of car batteries are lead-acid, Valve-Regulated Lead-Acid (VRLA), nickel-metal-hydride, and lithium-ion. Each type has its advantages and disadvantages.

Lead-Acid 

Lead-acid is the most common type of battery. It's inexpensive, stores a lot of energy, but it's heavy, and it doesn't last as long as the other types of batteries. But you can charge your batteries using Battery Trickle Chargers to keep your batteries safe.

VRLA

Valve-Regulated Lead Acid (VRLA) is more expensive than a lead-acid battery, but it doesn't require maintenance, and you don't need to check its electrolyte levels. It's also lighter than a conventional car battery. The biggest problem with this kind of battery is that it can explode.

Nickel-Metal-Hydride

Nickel-metal-hydride is the newest type of battery on the market today. It's lightweight and doesn't require maintenance, but it's more expensive than both lead-acid and VRLA batteries. They also don't last as long as lithium-ion batteries since they deteriorate faster when stored in a discharged state.

Lithium-Ion

Lithium-ion batteries are the most expensive type of battery, but they have a lot of advantages over the other types of batteries. They're lightweight, last longer than any other battery type, and don't require maintenance. The only downside is that they can be dangerous if not handled properly.

Things To Consider While Purchasing Car Batteries

Battery Size And Capacity

Car battery size is measured by the number of ampere-hours (Ah) it can hold. The higher the Ah capacity, the longer its life will be and the heavier it will carry around. It must have a minimum reserve capacity for proper functioning during extreme weather conditions such as hot and cold weather. However, you can check Car Audio Batteries to keep your car music system outstanding and enjoy music for a long time.

CCA Rated And Spillproof Batteries

A battery that is not CCA rated may still be used, but it is best to choose a battery with the correct CCA rating for your car. The best car battery must be spillproof and have a tight case cover to prevent leakage of electrolyte and acid fumes that can damage the vehicle's electrical wiring system.

Immobilizer Protection

It should also have immobilizer protection which protects it from theft by disabling the engine when anyone tries to start it without disconnecting or removing its battery.

Cranking Power

Car batteries must have a high cranking power to start the engine even in extreme weather conditions and start with low voltage input from the starter motor. The best car battery has good vibration resistance like AGM Marine Batteries that can withstand vibrations during normal driving and rough road use.

Conclusion

In conclusion, you must take the time to research and understand the different types of car batteries available before making your purchase.  By following the tips in this guide, you should find the perfect battery for your vehicle. Enjoy shopping.
