Car Battery Jargon Explained

The battery is a vital part of your vehicle’s components. Without an effective battery, your car isn’t going anywhere. The mixture of fuel and air in your engine’s combustion chamber is ignited by starting up the battery and this then runs all the electrical gizmos inside the vehicle. Of course, it gets a lot more technical than that but for most of us, the scientific explanation is not needed. What is needed, however, is a basic understanding of the jargon when it comes to choosing the right battery for our car. Here we attempt to explain what some of this jargon means:

Amperage/AH

AH stands for Ampere Hours and means the sustained power a battery can omit on a constant basis. Most cars will only take a certain power level of the battery. If you intend on running lots of electrical components, built-in gadgets etc then you might want to choose a battery with a slightly higher AH.

CCA

Most often seen as a 3-digit number, CCA stands for ‘Cold Cranking Amps’. This tells you about the battery’s ability to give enough power to get the starter motor running during cold weather. Cold engine parts will have more resistance than warm ones, so the battery needs that little extra push to get things running.

Charge

Batteries need constant charging, and this normally takes place through regular usage, levels being topped up by the alternator.

Cycle

When a battery has gone through the complete process of discharging all its energy and being recharged, it is said to have gone through a cycle. For an online Car Battery Supplier, visit Car Battery Supplier Groves Batteries

Deep Cycle

A battery said to be ‘deep cycle’ means it has been designed to go for longer periods of time before needing to be charged again.

Electrolyte

This is a substance containing electrically charged particles called ions. Sulphuric acid is the electrolyte used in most standard lead-acid batteries. Mixed with water, this provides the perfect solution for storing electrical power.

Elements

The various rows of both positive and negative plates inside a battery are called elements.

Lead Acid Battery

These are the most commonly available car batteries. They consist of a plastic container filled with water, sulphuric acid, lead plates, and elements.

SLA

A Sealed Lead Acid battery is regulated by valves and requires no maintenance. They also cannot leak and due to this can be positioned in any way, sideways or upside down.

Starting Battery

This is a battery designed with extra CCA for quick, smooth start-ups even in cold weather.

Sulphation

This causes many batteries to fail. If a semi-charged battery is not used for a period of time, then sulphation can occur which causes an unpleasant ‘eggy’ aroma to emit from under the bonnet of your car.

Terminals

These are the two pegs that stick up from the top of the battery and are used to attach the electrical cables.

Voltage

This refers to the power that is needed to run the battery energy around the vehicle. Most vehicles operate on a standard 12 volts.
