Car Battery Buying Guide

The car battery can be an absolute nightmare when it goes wrong as it is required for almost every electronic device in your vehicle. Even when starting your vehicle, you may think that it is something mechanical but often it is simply a battery that is not produce enough cranking power.

Obviously, not all cars will use the same battery and some require far greater power compared to smaller vehicles. Using the wrong battery can cause unnecessary stress upon other components and therefore, its important to get the correct battery.

Below we cover every aspect of a car battery to hopefully improve your knowledge and ensure you get the best bang for your buck.

Types of Car Battery

Car batteries can be recognized as two different types, which include a lead acid battery, which is a standard car battery and the more modern AGM battery (Absorbed Glass Mat). Both come with separate benefits as discussed below.

The lead acid battery is the cheaper of the two and much more widely used with car owners. Older lead batteries use to require regular maintenance by topping up the water in the electrolyte solution. However, these days they are maintenance free and retain their fluid. The one major downfall with a lead battery is that they cannot hold charge for as long as the AGM alternative and may suffer from long discharges.

As car battery technology has improved, the more modern AGM battery has been the first choice for many car owners. This is due to the ability to withstand many recharging cycles and repeated draining. On top of this, they have been designed to withstand modern luxuries found in the cars of today such as stop-start systems, additional electronic load and much more.

Cold Cranking Amps

Cold Cranking Amps is often referred to as CCA and it is measured by the number of amps a battery can output when the temperature is at zero degrees Fahrenheit.

For drivers of large gas engines or diesel powered vehicles, this is a figure you should be looking out for. Diesel cars in particular draw a large amount of current in order to heat the glow plugs and start the car and having a large amount of CCA will help starting the car in cold weather in the winter.

The majority of car batteries will be labelled with either a letter “N” or “S”, which means North for cold weather and South for hot weather. When choosing a battery, you should pay close attention to this label and the climate you live in.

Service Life and Warranties

When purchasing top rated car batteries, you expect to have a longer service life compared to a cheap battery. This is often the case with Odyssey batteries leading the pack with up to 10 years of battery life.

New car batteries should almost all come with a warranty that should at least be 2 years. Many reputable brands have longer but comes with an increased price tag.

A car battery can lose health by general poor maintenance. For example, letting the battery drain frequently to the point that it requires jump starting is not ideal. Using a portable jump starter once or twice in its whole life time won’t do much damage but every other week certainly will.

If the car is not used regularly, we highly recommend using a car battery maintainer, that ensures the battery level is topped up to a safe level all the time.

How to Diagnose a Dead Car Battery

If you car battery goes flat, don’t immediately think that it is dead and now unusable. Many car owners will do this and spend unnecessary money on a brand new car battery, which of course is not cheap. Below are some signs that your car battery is dying and you need a new one:

  • Low battery fluid/acid level
  • Slow cranking of the engine (Even more so when its cold)
  • Old age (Usually above 8 years)
  • Leaking battery near the positive and negative connections
  • Engine Management light appearing unexpectedly
  • Many jump starts in a short period
  • Working some days and not the other days

If you are experiencing multiple of the above symptoms and have a fully charged battery, then its probably dead. However, if it is not fully charged, it may be struggling to recharge and especially so if you are only doing small trips. We highly recommend using the best car battery charger you can get your hands on and allow the battery to reach full charge and then test the battery again before purchasing a new car battery.

To save money, many people may opt for a second hand car battery, however we strongly recommend that you do not. You may get lucky but half the time you may find yourself getting out the jumper cables from the trunk and asking for help.

At the end of the day, even the best car battery is not too pricey considering their life expectancy and high performance.

Top Battery Brands

  • Odyssey
  • Optima
  • Bosch

How to Safely Remove a Car Battery

Whether your car battery has died or you are using the battery elsewhere, there is a safe way to remove the battery. To safely take a car battery out of the car, use the following steps to safely remove your car battery:

  1. Turn your engine off. Ensure you are in park (or in gear for manual cars) and you have the handbrake applied.
  2. Open bonnet and place pad over wing. Ensure that the bonnet is at its highest position and that the protective pad or blanket is placed on the wing. This ensures that no battery acid leaks out onto your paintwork.
  3. Remove any bolts or straps that are holding it in. To ensure that the battery doesn’t move around whilst the car is being driven, there are usually bolts or straps holding it in place. Remove these in order to take the battery out with ease (as shown in image above).
  4. Remove negative cable connection first. The negative cable is removed first because its connected to the chassis of the car. Removing the positive cable first could cause a short if you accidentally hit the chassis with a wrench. Starting with negative, use a wrench to loosen the nut and pull up the cable with your hand. Repeat for the positive cable.
  5. Remove the car battery. Take the battery out slowly, avoiding hitting the paintwork and place out of the way. If its leaking, do not let the battery acid drip onto any paintwork, clothes or yourself.

It is always good practice to clean up the battery tray of any debris or rust build up. When cleaning, ensure that you use gloves in case there is acid present.


Your car battery is a critical part of any vehicle you own and without it, you will be unable to start your car or use any electronics inside the car. For this reason alone, its worth paying the extra for the best car battery you can buy. All of our recommendations above are suitable for a range of vehicles, conditions and budgets.
