Sealed Lead Acid Battery Questions

Also called SLA, VRLA (valve-regulated lead-acid battery), sealed lead acid batteries have many applications in the current world. From contemporary bikes, ATVs, house alarm systems, toys, backup systems, exercise gear, generators and the list continues. These batteries are available in all shapes, voltages, amperages and dimensions. If you’re not familiar with SLA batteries, then this guide will assist with any questions that you might have. Additionally, it’s encouraged to read if you’re considering replacing your present sealed lead acid battery.


Do I Have To Use The Same Battery Manufacturer?

No, you might use different manufacturers so long as the voltage and measurements fit your original battery. The gap in power (Ah) shouldn’t harm your unit. Check your system manual for maximum and minimum power requirements.

Can I Select An SLA With Different Capacity?

You may pick a battery using another capacity provided that it’s within exactly the exact same selection. By way of instance, if your existing battery is 4Ah you can pick a battery that’s rated at 4.5Ah or 5Ah. Be aware; the battery dimensions can change with a greater capacity. Always match your present voltage and size into the replacement you choose.

What Is The Life Of An SLA Battery?

The existence of a sealed lead acid battery depends upon a range of variables such as program, operating temperature as well as the charging system. Generally that an SLA will endure between 300-500 cycles. Never keep the battery in a discharged or partially charged condition. To prolong the life span of your battery life, make sure you recharge your battery .


What Is The Shelf Life Of My Sealed Lead Acid Battery?

Each of SLA batteries self-discharge. If the battery isn’t recharged occasionally, its whole capacity might not be recoverable. Ordinarily, SLA batteries self-discharge 3 percent each month. We advise that you recharge and check every 3 months. SLA batteries shouldn’t be kept longer than six weeks without being recharged. Store the battery in a dry, cool location.

Do I Need To Drain My Sealed Lead Acid Battery To Prevent Memory Effect?

No. Draining your SLA battery may lead to damaging it.

The Battery Is Swollen, What Does That Mean?

Immediately remove the battery in the device. A battery gets bloated because of overcharging. Excessive current will flow in the battery following the battery has reached a complete charge. The continuous current will lead to decomposition of the water from the electrolyte and early aging. At elevated levels of overcharge a battery will progressively warm upward. As it gets warmer it will take more present, heating up much farther. This is known as thermal runaway and it could ruin a battery in as little as a couple of hours.

How To Connect A Battery In Series And Parallel?

It’s possible to join your own SLA battery in parallel or series. Joining your SLA batteries in string will create a greater voltage. By way of instance, linking two 12 Volt batteries will provide you an output of 24 Volts.

Joining your batteries in parallel increases the capacity (Ah). To learn more, please reference to’Joining Your SLA Batteries Together’.

How Do I Charge The SLA Battery?

Some machines charge the SLA battery, such as some house alert or backup systems. Meaning, you don’t need to take the battery out and control it on a battery tender.

Should you have to control your SLA battery with a battery tender, then picking out the suitable battery charger can affect the operation and service life of a sealed lead acid (SLA) batterycharger. As a general rule of thumb when choosing a charger for an SLA battery would be to use one which is no more than 20 percent of their potential rating of the battery (in a 20hr. Speed ).

Case in point; to control a 12 volt / 7.5Ah battery pick a charger with a maximum cost output of 1.5 Amps (7.5 x 0.20 = 1.5).

What Terminal Do I Need?

Since SLA batteries have been employed in an assortment of merchandise, batteries can be found in many different different terminal configurations. Please consult with our battery terminal webpage for dimensions and pictures of the various terminals.

I Dropped The SLA Battery, What Do I Do?

Please use protective equipment before tackling the battery to prevent exposure to sulfuric acid. Use rubber or neoprene gloves, safety glasses, acid resistant boots, apron as well as clothes. Neutralize any spilled electrolyte or exposed battery components with soda ash or sodium bicarbonate until fizzing stops. Set the broken battery in a heavy gauge plastic tote or other non-metallic container. Recycle the battery instantly. Don’t store old lead acid batteries, particularly lead acid batteries with a broken case.

How Do I Recycle My SLA Battery?

Go to our Battery Recycling page to learn more about how to correctly dispose of your sealed lead acid battery.

SLA, VLRA, AGM, Is There A Difference?

SLA (Sealed Lead Acid) and VRLA (Valve Regulated Lead Acid) are unique acronyms for the identical battery. This battery type includes the following attributes: Maintenance-free, leak-proof, place insensitive. Batteries of the type have a security port to discharge gas in the event of excessive internal pressure build up. AGM (Absorbed Glass Mat) refers to a certain sort of SLA/VRLA in which the electrolyte is absorbed to separators between the plates composed of sponge such as good glass fiber mats. SLA batteries have been split up into certain subsets batteries.

AGM And Gel Cell Batteries Difference?


The two kinds of batteries have been sealed, valve regulated batteries permitting them to be utilized in virtually any position. The difference is in the method by which in which the electrolyte is immobilized. At a gel-type battery that the liquid electrolyte becomes a gel directly after the battery is stuffed. Gel batteries utilize another sort of separators that aren’t absorbent. Due to the plan, gel cell phones do not offer you the exact same power capability as do precisely the exact physical dimension AGM battery. By way of instance, an AGM battery that’s 12V 100AH, whereas, by way of instance, a gel cell battery at precisely the exact same size case would just be graded at 84AH. On the other hand, the Gel Cell excels in slow release prices and slightly higher working temperatures. The inner design is differently.

GEL Vs. (AGM) Sealed Lead Acid Batteries

Enough liquid to keep the mat moist with all the electrolyte and when the AGM battery is broken no free liquid can be found to escape.

Gel Cell batteries feature a silica kind gel where the battery electrolyte is suspended. This thick paste-like substance enables electrons to flow between plates however won’t flow in a gel if the instance is broken.

More frequently than not, AGM batteries have been wrongly recognized as Gel Cell Batteries. Both batteries have similar characteristics like being non-spillable, able to be mounted at almost any position, very low self-discharge, safe to be used in restricted ventilation regions, and could be transported via ground or air securely without any special handling.

AGM Batteries are favored when a great deal of amps could be deemed necessary. Typically, recharge can be done with a fantastic quality conventional battery charger. The lifetime expectancy (quantified as cycle lifetime ) remains excellent in many AGM batteries if they aren’t discharged more than 60 percent between recharges and/or recharged completely every 3-6 weeks.

Gel Cell Batteries don’t offer you the exact same power capability as do precisely the exact same physical dimension AGM batteries. On the other hand, the Gel Cell excels in slow release prices and slightly higher working temperatures and with exceptional deep cycle capacity. 1 large problem with Gel Cell batteries that have to be addressed is your CHARGE PROFILE. Gel Cell batteries have to be recharged properly or so the battery will endure premature failure. Please refer to this specification sheet to get the maximum charging current limitation.
