What is the difference between SLA and VRLA batteries?

SLA and VRLA are different acronyms for the same battery, Sealed Lead Acid or Valve Regulated Lead Acid. AGM, Absorbed Glass Mat refers to a specific type of SLA/VRLA where the electrolyte is absorbed into separators between the plates consisting of sponge like fine glass fiber mats.
  • Is there lead in batteries?

    Lead and lead dioxide, the active materials on the battery's plates, react with sulfuric acid in the electrolyte to form lead sulfate. The lead sulfate first forms in a finely divided, amorphous state, and easily reverts to lead, lead dioxide and sulfuric acid when the battery recharges.
  • Can you charge an AGM battery?

    Some have different settings for charging flooded, gel and AGM batteries. It's quicker to charge at higher amperage, but it also can generate a lot of heat, which reduces the life of a battery, just like the heat of summer. Alternators are NOT chargers. Don't rely on your alternator to do the work of a charger.
  • Can you charge a gel battery?

    Gel cell batteries are deep cycle batteries that contain an electrolyte which is suspended in a gel solution between lead plates. You can recharge a gel cell battery with a gel cell battery charger. Constant voltage charging is one of the best charging methods, which you can accomplish in one of two ways.

How does a VRLA battery work?

A VRLA battery utilizes a one-way, pressure-relief valve system to achieve a “recombinant” technology. This means that the oxygen normally produced on the positive plate is absorbed by the negative plate. Water (H2O) is produced instead, retaining the moisture within the battery.
  • What is the meaning of SMF in battery?

    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. Just like other batteries, it also emit H2 and O2 gases and due to sealed batteries both these gases combine to form water.

  • What voltage to charge an AGM battery?

    Deep Cycle AGM:- AGM batteries should be charged using a charger with a mode switch for AGM type batteries. It is recommended to use a charger, current limited to 20% or 0.2C of the batteries capacity at a charging voltage of between 14.6 – 14.8V following deep cycle use, or 13.6V13.8V for standby use.
