Why are VRLA Gel batteries so called?

VRLA Gel batteries are so called because they are VRLA (which is what makes them maintenance free) and they use gel.

What does Gel or T Gel stand for?

Gel or T Gel stands for thixotropic gel. Gel batteries or T Gel batteries are the same as VRLA Gel batteries. They are one and the same.

VRLA Gel batteries use a composite separator made of a glass mat bonded to a porous polyethylene or polyvinylchloride sheet. The batteries are then filled with a thixotropic gel mixed with sulphuric acid.

What are the advantages of VRLA Gel batteries?

Advantages of VRLA Gel batteries are:

  • Perform better than VRLA AGM batteries in regular deep discharge (>80% DOD) applications
  • Perform better than VRLA AGM batteries in low power applications

What are the disadvantages of VRLA Gel batteries?

Disadvantages of VRLA Gel batteries are:

  • Higher self-discharge rate compared to VRLA AGM batteries
  • Don’t perform as well as flooded or VRLA AGM batteries in cold temperatures (<40° F)
  • Don’t perform as well as flooded or VRLA AGM batteries when they regularly reach a shallow depth of discharge (<20% DOD)
  • More expensive than flooded and VRLA AGM batteries

Do you have VRLA Gel batteries?

Yes, we have VRLA AGM batteries.
