Sealed Lead Acid


Imagine that you are a sealed lead acid battery.

As an industry professional, you’re adaptable — and so are SLAs. You don’t require constant maintenance, just like an SLA. And you’re efficient, same for SLAs. Well, SLAs aren’t completely maintenance free because they do require cleaning and regular functional testing. But hey, so do you!

In all serious, SLAs, also known as valve-regulated lead-acid batteries to be official, are a type of lead-acid rechargeable battery. They’re the oldest type of rechargeable battery, and quite maneuverable. Due to their construction, some types — like the Gel and AGM types — can be mounted in any orientation.

Very basically, lead-acid cells consist of two plates of lead, which serve as electrodes that are suspended in diluted sulphuric acid, which then becomes the electrolyte. In common lead-acid cells, the diluted acid is in liquid form (flooded or wet cells). Also, the liquid could be turned into a paste-like gel by the addition of silica and other gelling agents (gel batteries).

What you really need to know is that SLAs can be widely used in large portable electrical devices and off-grid power systems, where large amounts of storage are needed at a lower cost than other low-maintenance technologies (like lithium-ion.

There are four primary main sealed lead acid battery types, with each specifically designed to best perform under certain conditions: general-purpose SLA batteries, deep-cycle SLAs, gel SLAs and high-rate SLAs.

The general-purpose is the most often used and accommodates the most applications. They work well for discharging and recharging and for back-up, with common applications including emergency lighting, security systems, consumer electronics and sump pumps.

Deep Cycle batteries provide excellent cycle life and are best used in demanding applications where the battery will be frequently discharged and recharged. Applications range from wheelchairs and scooters to marine product and lawn/garden equipment.

Gel batteries are ideal for customers who use their batteries very frequently or require their batteries to last a long time. They provide the greatest number of cycles compared to general purpose and even deep cycle batteries. Importantly, they require a different charging voltage than other SLA batteries, along with a charger specifically designed for them must be used. Among typical applications are wind generation, water pumping, remote monitoring and floor scrubbing.
Finally, high-rate batteries are different from the other types — they’re the SLA on steroids. They deliver higher watts per cell than traditional batteries, have a longer life, require minimal maintenance and typically have longer warranties than other SLA battery types. Note: They should never be used as the main source of power every day, unlike deep cycle or gel SLA batteries. Applications include medical equipment, internet housing sites and data centers.
