A beginner’s guide to batteries

When you're in the market to buy a new battery it can be overwhelming to have so many choices in front of you. In this article, we aim to give you a helpful overview of the different types of batteries and uses. We'll cover starting, semi-cycling, dual-purpose and deep cycle batteries. Understanding the differences and purposes between these batteries is crucial to selecting the right one for your needs.

Starting batteries: powerhouses to start up your engines

Also known as cranking batteries, starting batteries deliver a quick burst of power to start an engine. They are designed to provide a large amount of current rapidly and this is their main purpose. Starting batteries are not intended to be used for sustained power over an extended time. Doing so can cause damage to the battery. Starting batteries are commonly used in automotive capacities. They're helpful for starting cars, motorcycles and trucks.

Deep cycle batteries: sustained power over time

In contrast to starting batteries, deep cycle batteries are designed for sustained power. They can withstand deep discharges and also recharges. Deep cycle batteries do this without significance performance or capacity loss. Their characteristics make them ideal for applications requiring a reliable power source for extended periods. Common uses of deep cycle batteries include caravans, RVs, boats and solar energy systems.

Starting and semi-cycling batteries: a hybrid solution

Starting and semi-cycling batteries combine the characteristics of both starting batteries and deep cycle batteries. They have high cranking power and limited cycling capabilities. This means they have the ability to start engines and occasionally be used for longer periods of time. However, they are not ideally used for long-term, deep cycling applications. These batteries are useful for situations where someone wants the ability to start an engine and have some ability to power accessories in vehicles.

Dual-purpose batteries: the all-rounder

Dual-purpose batteries have effective starting and deep cycling capabilities. They provide the high cranking power required for engine start-up and can also handle moderate cycling. These batteries are widely used in marine applications and other scenarios where someone might want a reliable combination of starting and cycling capabilities.

Choosing the right battery for your needs

In summary, each type of battery serves a specific purpose in different applications.

• Starting batteries are tailored for high cranking power.
• Deep cycle batteries offer continuous and sustained power.
• Starting and semi-cycling batteries give you engine-starting capabilities with added limited cycling.
• Dual-purpose batteries can get your engine started and provide deep cycling that gives you power for extended periods.
