Tubular batteries last at least twice as long as normal flat plate batteries, this is because the positive active material does not shed off due to the protection offered by the tubes. Typical life ranges from 4 to 8 years. We will go in details what is a battery, how it works and the difference between tubular and normal batteries.
What is a battery?
A battery is a storage device for electrochemical energy which is being used for lighting and electrical applications.
What is the use of the battery in an inverter setup?
The battery is the backbone of your inverter system. The performance and life of an inverter largely depend upon the battery quality. The battery is responsive of the length during which your inverter will be able to run your equipment. This is what is called the battery capacity.
Which types of batteries are available.
Tubular Wet cell: This is the ideal battery for deep cycle usage with Luminous Inverters and Solar Home UPS. Designed exclusively for inverters and UPS, this is an excellent product that provides the longest duty life with minimal maintenance needs. This battery is particularly suitable for use in areas with frequent power cuts. The recommendation is to go for Tubular as they last much longer.
SMF AGM: Deep Cycle SMF (Sealed Maintenance Free) / VRLA Valve Regulated Lead Acid) batteries for backup applications, which although they are not perfect for inverters, do the job pretty well – without needing any maintenance whatsoever. We always recommend you choose a reputed brand, since there are many sub-par SMF batteries available in the market
SMF GEL: The SMF Gel batteries provide a good in-between option. They are usually much better than Standard VRLA batteries, utilizing specialized gel electrolyte to reduce negative plate sulphation in the battery, thus helping them to be last longer. They also have the added advantage of being maintenance free. Of course, this also usually means these batteries are more expensive than the Tubular or SMF ones.
Benefits of tubular batteries over flat batteries:
Why are tubular batteries most suitable in a UPS application?
A tubular battery uses technology that seals the active material in polyester tubes called gauntlets, instead of pasting it on the surface of the plate. As a result, there’s no shedding or corrosion, ensuring long battery life. Owing to their toughness and durability, tubular batteries can operate at extreme temperatures and are used in high cyclic applications involving frequent and prolonged power outages.
Bonus: What are the features that should be considered while buying a battery?
There are three primary points that need to be taken into consideration while buying a battery.
Size, Power and Warranty: When buying a new battery, we suggest you purchase a battery with the highest amp hour rating and warranty possible. Of course the physical size, cable hook up and terminal type must be taken into consideration too. Be sure to purchase the correct type of battery for the job it is expected to do. The freshness of a new battery is very important. The longer a battery sits idle and is not re-charged, the more damaging sulfation build up there may be on the plates. Most batteries have a code of the manufacturing date on them. Remember, the fresher the better!
