Power On! Getting Back to Basics With Different AGM Battery Types and More
The global battery market is projected to soar to $100 billion by 2025. This surge is driven by growing sustainability concerns, prompting more people to switch from fuel vehicles to electric-powered ones, including e-bikes. Additionally, the industry's growth has led to the increased use of battery-powered machines like forklifts in factories.
As a result, new battery consumers are emerging. But how much do you really know about batteries? Here's a comprehensive guide on AGM batteries and more to help you make the right choice.
Types of Batteries
When classifying batteries, there are two main approaches: by application or by construction.
Classification by Application
There are three primary types of battery applications: automotive, deep-cycle, and marine.
Automotive: Starting batteries, also known as SLI (Starting, Lighting, Ignition), are used to start and run an engine. They require a large amount of current for a short period and have a large number of thin plates made from a lead ‘sponge.’ These batteries can last for thousands of cycles in normal use but will fail after 30-150 deep cycles due to the rapid degradation of the lead sponge.
Deep-Cycle: These batteries are designed to be discharged up to 80% repeatedly. They have thicker, solid lead plates, which provide less surface area and lower ‘instant’ charge compared to starting batteries. To maximize their lifespan, it's best to keep the average cycle at 50%. If used for starting purposes, ensure the battery is 20% larger than a traditional starting battery to deliver the same cranking amps.
Marine: Marine batteries are a hybrid between deep-cycle and starting batteries. They have lead sponges like starting batteries but are heavier and coarser.
Classification by Construction
There are three main types of battery construction: flooded (wet cell), gelled, and Absorbent Glass Mat (AGM). All three contain lead acid but differ in their internal design.
Differences Between Flooded, Gel, and AGM Batteries
Each type of battery construction has its unique advantages and maintenance requirements.
Flooded Batteries: These use lead plates, plate separators, and a sulfuric acid electrolyte. They vent gases instead of recombining them, requiring regular maintenance to top up the electrolyte. Flooded batteries are cost-effective but have high resistance and the weakest internal construction.
Gel Batteries: Containing sulfuric acid turned into a jelly-like mass with Silica Gel, these batteries prevent spills even if broken. They require careful charging to avoid damage and have stronger internal construction than flooded batteries but are still weaker than AGM batteries.
AGM Batteries: Sealed and using a fine Boron-Silicate glass mat, AGM batteries are 95% saturated, preventing acid leaks even if broken. They are the most impact-resistant, have the least internal resistance, and are maintenance-free. AGM batteries also don't require special charging care and can use the same voltage as standard batteries.
Pick the Right Battery for the Job
The global demand for batteries, including AGM batteries, is growing as more people transition to electric vehicles and companies expand their use of battery-powered equipment. Before choosing a battery, it's crucial to understand its pros and cons.
