Seal Lead Acid Battery- Maintenance, Cycle Life And Leakage
If you are not sure what are seal lead-acid batteries? Or don't you know how to maintain it? So you have landed on the right page, as this guide helps get all the answers related to SLA battery!!
A valve-regulated lead-acid (VRLA) battery, commonly referred to as a sealed lead-acid (SLA) battery, is a type of lead-acid battery characterized by a limited amount of electrolyte ('depleted' electrolyte) absorbed in a plate separator or formed into a gel; the distribution of negative and positive plates to allow the recombination of oxygen within the cell and the presence of a relief valve.
There are two primary types of SLA batteries:
1.Absorbent glass mat (AGM)
So are you ready? Let's get in!!
How do you maintain a sealed lead-acid battery?One of the best purchases you can make is buying an SLA (Seal lead acid) battery. Renowned for their great heat resistance and longevity, these batteries will give you 10-15 years of steady output if you take good care of them. SLAs do not need a lot of upkeep, but this does not indicate that they are resistant to damage or decreased performance. You must take proper care of your SLA batteries to provide you with optimum output for as long as possible.
Let's dive into knowing the methods on how you can maintain your SLA batteries.
Lead-acid batteries are vulnerable to undercharging and overcharging, which means that you need to consider the battery's power and ensure that it is ultimately charged at all times. You should also ensure that the battery is not discharged below critical levels. Overcharging and undercharging decrease the battery's power and dramatically reduces its existence. If you care about your SLA battery, consider its power and invest in a voltmeter or other measurement tool to calculate the voltage at regular intervals when the battery is being charged and in service.
?Use The Right Charger At All Times
In addition to controlling the charging speed, it is important to ensure that the correct charger charges the batteries. A good charger should be both temperature and voltage-controlled to avoid overcharging and damaging the battery plates.
?Store The Battery In Good Conditions
SLA batteries are responsible for self-discharge, and if you do not store them carefully, their life cycle will be shortened. Immediately after use, these batteries are usually very hot, and if you don't store them in a well-ventilated space, self-discharge will be easy. It is advisable to keep SLA batteries away from the elements in a cool, dry, well-ventilated space. Batteries should not be close to opening flames because they can quickly catch fire and combust, causing accidents.
If you keep the battery for too long, it is good to practice to take the voltage readings on a monthly basis and to raise the charge accordingly. Storing the battery for too long would discharge it, and if you use it in that condition, you risk spoiling the battery plates. Batteries are not recommended to be kept for longer than six months without usage.
?Keep The Terminals Clean
After charging or after use, ensure that the battery terminals are washed to remove any residue on the terminals' surface. Residue on the battery terminal's surface decreases the batteries' performance, and its power is not entirely exploited. Take good care of your SLA battery, and in return, it will serve you for several years.
How long do sealed lead acid batteries last?Based on the manufacturing process of the battery, sealed lead-acid batteries will have a life span of anywhere from 3-5 years all the way up to 12+ years.
The life of the sealed lead acid battery will depend on a variety of factors, including application, operating temperature, and the charging process. Never keep your battery in a discharged or partially charged state. To prolong the life of your cell, make sure to recharge your battery in advance of storage.
Can sealed lead acid batteries leak?Sealed Lead Acid batteries (SLA) are specially designed to be fully maintenance-free. Sealed Lead Acid batteries fall In the group of VRLA (valve-regulated lead-acid) batteries. As opposed to normal flooded lead-acid batteries, they do not need the daily addition of water to the cells ventless steam.
The electrolyte (battery acid) in an SLA battery is fixed in the battery and sealed using special pressure valves and will never be opened. These batteries are engineered to be leak-proof and non-spillable and can therefore operate without leakage in either place. When the SLA battery is opened and correctly treated, sealed lead-acid batteries do not pose a risk of leakage without physical damage to the case.
Absorbent Glass Matting
Modern Sealed Lead Acid batteries also use Absorbent Glass Matt (AGM) technology; small thin fiberglass strands that have been woven into a mat are made of Absorbent Glass Matt. For the battery to function properly, the mat is built to contain the amount of electrolyte (battery acid) required for each cell.
Due to its acidic nature, the absorbent glass mat will not absorb the acid but will retain it and is not susceptible to damage. Sandwiched between plates, the absorbent glass mat is gently squeezed and soldered or welded in place. Sealed lead-acid batteries are particularly resistant to vibrations because of the tight quarters inside the battery.
The absorbent glass mat is built to retain the acid and not spill when a sealed lead acid battery with AGM technology is broken. Sealed Lead Acid AGM batteries have much less electrolyte (battery acid) than regular lead-acid batteries, often referred to as an acid starved battery.
ConclusionTake good care of your SLA battery, and in return, it will serve you for several years. We hope the above tips for maintaining your SLA battery will help you get the most out of it.
