FAQs - VRLA batteries
How are VRLA batteries constructed?
All lead acid batteries are constructed from positive and negative lead plates connected in series to make 2V cells. The electrolyte can be in many forms and immobilised in different materials depending on the battery technology.
There are two main subtypes of lead acid battery – traditional flooded wet cell batteries and Valve Regulated Lead Acid (VRLA) batteries. Note - VRLA batteries are sometimes referred to as Sealed Lead Acid (SLA) batteries.
VRLA batteries are different to flooded wet cell batteries because they are designed in a way so that they can be tilted without leaking acidic chemicals. Another important feature of VRLA batteries are the valves which sit at the top above the battery to release gas as the battery pressure increases.
There are two primary types of VRLA batteries available - AGM (Absorbent Glass Mat) and Gel. Both AGM and Gel batteries have the same container, plates and pressure relief valves. The difference comes down to the type of separator used which sits between the lead plates. Each type of separator has certain advantages and disadvantages when used in different applications. The plates thickness, quantity and structure differs between these battery technologies.
VRLA batteries are being more commonly used in a wide range of applications due to their advantages over flooded wet cell batteries.
What are the benefits of using VRLA batteries?
Unlike flooded wet cell batteries, VRLA batteries can be installed either upright or on-side as they are considered to be “sealed” and therefore spill proof.
VRLA batteries are also maintenance free and therefore do not require to be topped up with water.
Other benefits include:
- Very low/no gassing
- Minimal corrosion
- Ability to function well in high temperature and cyclic sites
- Air transportable - they can be shipped as non-dangerous goods
- Lower impedance
What applications are VRLA batteries ideal for?
- Fire and pumping (e.g. diesel starting pumps for fire systems)
- Security systems
- IT infrastructure
- Emergency lighting
- Industrial controls
- Mobility scooters
- Electric wheelchairs
- Solar powered road signs (VMS boards, portable traffic lights, radar signs etc)
- Electric vehicles (gold buggies, floor cleaning machines etc)
- Solar lighting
- Material handling equipment
