What is a Sealed Car Battery?
A sealed car battery, also known as a Valve Regulated Lead Acid (VRLA) battery, is a type of lead-acid battery characterized by a limited amount of electrolyte (“acid”) in the form of a gel or absorbed into a fiberglass mat. Unlike flooded lead-acid batteries, these batteries are designed to be maintenance-free, meaning you don’t need to add water or electrolyte periodically. They are sealed, preventing evaporation and spillage, and are safer to handle.
Sealed batteries come in two main types: Gel Cell and Absorbed Glass Mat (AGM). Gel Cell batteries use a jellified electrolyte, while AGM batteries use a fiberglass mat to hold the electrolyte. Both types are spill-proof, thanks to their sealed design, which also allows them to be mounted in virtually any position.
How it works and its common uses
Sealed car batteries work on the same basic principle as regular lead-acid batteries. They convert chemical energy into electrical energy through a series of chemical reactions. The main difference lies in the physical state of the electrolyte and the sealed design.
When you start your car, the battery supplies a burst of energy to the starter motor. Once the car is running, the alternator takes over to power the electrical systems and recharge the battery.
Sealed batteries are commonly used in cars, motorcycles, boats, and RVs, especially in applications that require a spill-proof battery. They are also used in UPS systems, alarm systems, and for many other industrial purposes.
In the automotive world, sealed batteries are often used in high-performance and luxury vehicles due to their superior vibration resistance and ability to deliver high currents. They are also favored in vehicles with advanced electrical systems because of their deep cycling capabilities.
While sealed batteries are maintenance-free, they are not entirely foolproof. They still need to be charged properly to prevent damage. Overcharging can lead to a condition called “thermal runaway,” which can destroy the battery.
Did you know that the first sealed lead acid battery was invented in 1957 by the Gates Rubber Company? They’ve come a long way since then!
“Sealed batteries are a game-changer in the automotive world. They offer safety, convenience, and high performance, making them a popular choice for many applications.”
