AGM vs. Lithium: Which on is right for you?

When it comes to deciding between an AGM battery and a Lithium battery, the application, intended use, expected life expectancy and budget play a major role.

There can be many issues that need to be factored in your purchase. We have put together a Pro’s and Con’s list to help highlight the advantages of each.

Pro’s of AGM Batteries

AGM batteries are more affordable

They deliver a higher output – provide high bursts of power when required such as starting an engine or providing emergency or backup power. AGM’s also have high charge acceptance.

They are spillproof – AGM batteries can be placed in any orientation which offers greater mounting flexibility as they will not leak

They are durable – AGM batteries are designed to be sturdy, handling vibration particularly well

They are resistant to vibration – The electrolyte soaked glass mats in between each lead plate act like a damper. The plates are compressed between the mats making AGM batteries highly resistant to vibration. This makes them suitable for vehicles that operate in high vibration conditions (i.e. ATVs, 4WDs & SUVs).

Con’s of AGM

AGM batteries have a shorter cycle life compared to Lithium batteries

AGM batteries can only be discharged to 50% Depth of Discharge

Costly to produce due to the design of AGM batteries, extra steps are required in the manufacturing process and cannot be produced using the same manufacturing equipment as their flooded counterparts

AGM batteries struggle to disperse heat. As heat impacts battery ageing and cycle life, it is not recommended to install AGM batteries in environments subject to high temperatures.

AGM batteries – for a wide variety of applications and uses.

Recreational AGM Batteries – powering long distance journeys on recreational vehicles. AGM Batteries are also resistant to vibration making them suitable for all kinds of terrains in Australia and New Zealand.

Deep cycle AGMs batteries are commonly used for powering accessories and are ideal as secondary batteries in caravans, campers and 4x4s. They are also suitable for seasonally used applications such as ATVs, UTVs and Powersport vehicles which require high power and vibration resistance.

Automotive AGM batteries are commonly used in vehicles with high-electrical demands such as those with Stop Start technology. By not idling, Stop Start technology reduces fuel consumption and CO2 emissions making it a win-win situation for the planet and the wallet.

General purpose AGM batteries are perfect for everyday use and are suitable for alarm systems, automation systems, vending machines, electronic equipment, e-scooters, bikes and more.

Industrial AGM batteries are suitable for applications such as aerial work platforms, floor sweepers, floor scrubbers, material handling and backup power systems. These batteries are high performing, long lasting, resistant to the stress of repeated cycling and are maintenance free.
