What is an SMF battery?

What is an SMF battery?

SMF (Sealed Maintenance Free) batteries also known as the Valve Regulated Lead Acid (VRLA) batteries. These flat plate batteries that do not require topping-up and normally do not emit any fumes or gases on a continuous basis. The latest gas recombination technology ensures no emission of fumes.

Where SMF batteries are used?

VRLA/SMF batteries have a wide array of applications, which include inverters, automotive industry, emergency lights, solar industry, weighing machines, UPS systems, telecom equipment, emergency lights and small home UPS systems.

What is a battery in construction?

Battery Construction A twelve-volt battery has six single cells in series producing a fully charged output voltage of 12.6 volts. A battery cell consists of two lead plates a positive plate covered with a paste of lead dioxide and a negative made of sponge lead, with an insulating material (separator) in between.

What is inside a sealed lead acid battery?

A Sealed Lead Acid Battery (SLAB, for short) is made up of plates, lead, and lead oxide solution with a 35% sulfuric acid to 65% water ratio.

What is the life of SMF battery?

6. If the equipment is not using for long time, it should be charged once in every week. If the battery is allowed to charge and discharge frequently, its life can be extended to 3-5 years.

What is C rate for battery?

The battery C Rating is the measurement of current in which a battery is charged and discharged at. The capacity of a battery is generally rated and labelled at the 1C Rate (1C current), this means a fully charged battery with a capacity of 10Ah should be able to provide 10 Amps for one hour.

Are bigger batteries better?

However, some may assume that it is referring to a battery that is physically bigger in size. If all specifications of the battery are the same, there is essentially no advantage of a physically bigger battery. In fact, it is better that the battery is smaller to suit the limited space available in a car.

What happens when a lead acid battery is overcharged?

OVERCHARGING A LEAD ACID BATTERY As a result of too high a charge voltage excessive current will flow into the battery, after reaching full charge, causing decomposition of water in the electrolyte and premature aging. At high rates of overcharge a battery will progressively heat up.

How do you bring a dead lead acid battery back to life?

Attach a battery trickle charger or a computerized smart charger to your old lead acid battery, and allow charging continuously for about a week to 10 days. The extremely slow charging rates dissolve the de-sulphation that kills the battery, and revives it back to being able to hold a usable charge.

Which battery is best for inverter SMF or Tubular?

Tubular Batteries Vs Normal Batteries

Tubular Batteries Normal Flat plate batteries
High Price. Affordable price.
Fast charging battery. Charges slowly compared to tubular batteries.
Recommended for high productive applications. Recommended for small homes and budget-conscious people.
Highly reliable Reliable

What is the meaning of SMF battery?

Answer Wiki. 3 Answers. SMF battery which means Sealed Maintenance Free battery are sealed completely because there is no need to add water. The electrolyte used is in the form of gel which fills the cavity of plates.

Why okokaya SMF batteries?

OKAYA SMF batteries are made with the modern Japanese technology, using the in house special lead-tin-calcium alloy and specially imported Absorbent Glass Mat, fabricated in tough ABS containers for increased durability. The latest gas recombination technology ensures no emission of fumes.

What is the operating temperature range of SMF batteries?

Permissible operating temperature range of SMF batteries is 15 deg C to 50 deg C, but using within an operating range 5 C to 35 C will extend service life. Below – 15 deg C, the battery changes its chemical composition and cannot hold a charge.

What are the different types of batteries used in substations?

Different types of battery used for auxiliary power supply in substations and power plants. In industrial or substation applications mainly three types of batteries are used namely: Vented / Flooded Lead Acid batteries. Sealed maintenance free batteries/Valve Regulated Lead Acid. Nickel Cadmium (Ni-cd) batteries.
