What is SMF Battery?

An SMF battery or also called Valve Regulated Lead Acid (VRLA) battery is simply a lead-acid battery in which the electrolyte has been immobilised in order to recombine hydrogen and oxygen. It has a sealed construction with pressure release valves to prevent gases from escaping, it is this which gives it its name.

What is SMF Battery Technology?

Because the electrolyte is no longer in a fluid state, due to being absorbed into a finely textured glass mat, the gases produced are not free to form bubbles and rise to the surface of the electrolyte. Instead, they are trapped in the immobilised matrix and forced to travel to the opposite poles by the pressure gradient produced when on charge. In a free liquid, this would be impossible.

What is AGM battery? What is AGM Battery technology?

AGM is the short form for Absorbent Glass Mat separator. It is in this separator which is made from 100% glass and feels like blotting paper, that the acid is stored.

AGM Battery uses:
12V AGM Batteries are suitable for Solar battery backup, UPS & Inverter systems, Switchgear & controls, Banks, Insurance & Office power backup, Traffic management systems

SMF Battery uses:

  • SMF Battery for inverter
  • SMF Battery for UPS
  • SMF Battery for Solar
  • SMF Battery for home inverters

Microtex 12v AGM battery – valve-regulated (VRLA) with high power density using absorbent glass mat are available in a wide range from 70Ah to 200Ah. VRLA 12v AGM Battery for the UPS & Inverter industry from Microtex are sealed maintenance-free batteries and come with assured quality. Microtex incorporates battery research and design from years of its own experience and that of reputed European Battery Scientists. Microtex 12v AGM battery series – delivers trouble-free performance with an ultra-long life on float applications. They are supplied in a charged condition ready for use.

What is VRLA SMF Battery? What is difference between VRLA and SMF battery? what does AGM stand for?

VRLA stands for Valve Regulated Lead Acid battery & SMF stands for Sealed Maintenance Free. Both are characteristics of a 12V AGM Battery. AGM stands for Absorbent Glass Mat separator.
