Car Battery Buying Guide
Every car requires a working battery in order to start the car. The battery of course operates a range of features including power windows, lights, stereo, on board computer, engine systems and much more.

There are a range of factors to consider from the correct battery for your car, fuel type, sizes and much more. Take a read of the buyers guide to increase your knowledge for the best buy for your needs and requirements.
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 cold starting.
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.

The best brand car batteries in the US are Optima and Odyssey whereas in the UK, almost all top rated batteries are Bosch.
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 fully recharged your battery, then its probably dead. Before throwing it away, be sure to bring the battery back to live with a powerful jump starter and test to see whether it holds its charges once more.
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:
- Turn your engine off. Ensure you are in park (or in gear for manual cars) and you have the handbrake applied.
- 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.
- 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.
- 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.
- 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.
