Gelled Electrolyte (gel) and Absorbed Glass Mat (AGM) Batteries

Valve-Regulated Lead-Acid (VRLA):

EAST PENN Expertise and American Workmanship


Introduction

Valve-regulated lead-acid (VRLA) technology encompasses both gelled electrolyte and absorbed glass mat (AGM) batteries. Both types are valve-regulated and have significant advantages over flooded lead- acid products.

More than a decade ago, East Penn Manufacturing began building valve-regulated batteries using tried and true technology backed by more than 50 years experience. East Penn’s unique computer-aided manufactur- ing expertise and vertical integration have created a product that is recognized as the highest quality, longest lived VRLA battery available from any source.

East Penn’s gel and AGM batteries are manufactured to tough quality standards. East Penn manufactures high power gel and AGM batteries with excellent performance and life.


Applications

VRLA batteries can be substituted in virtually any flooded lead-acid battery application (in conjunction with well-regulated charging), as well as applications where traditional flooded batteries cannot be used. Because of their unique features and benefits, VRLA batteries are particularly well suited for:

Deep Cycle, Deep Discharge Applications

• Marine Trolling • Electronics • Sailboats • Electric Vehicles • Wheelchairs • Golf Cars • Portable Power • Floor Scrubbers • Personnel Carriers • Marine & RV House Power • Commercial Deep Cycle Applications

Standby and Emergency Backup Applications

• UPS (Uninterrupted Power Systems) • Cable TV • Emergency Lighting • Computer Backup • Solar Power • Telephone Switching • Village Power

Unusual and Demanding Applications

• Race Cars • Air-transported Equipment • Off-road Vehicles • Wet Environments • Marine & RV Starting • Diesel & I.C.E. Starting


What is a gel battery?

A gel battery is a lead-acid electric storage battery that:

  • is sealed using special pressure valves and should never be opened.
  • is completely maintenance-free.*
  • uses thixotropic gelled electrolyte.
  • uses a recombination reaction to prevent the escape of hydrogen and oxygen gases normally lost in a flooded lead-acid battery (particularly in deep cycle applications).
  • is non-spillable, and therefore can be operated in virtually any position. However, upside-down installation is not recommended.

* Connections must be retorqued and the batteries should be cleaned periodically.

What is an AGM battery?

An AGM battery is a lead-acid electric storage battery that:

  • is sealed using special pressure valves and should never be opened.
  • is completely maintenance-free.*
  • has all of its electrolyte absorbed in separators consisting of a sponge-like mass of matted glass fibers.
  • uses a recombination reaction to prevent the escape of hydrogen and oxygen gases normally lost in a flooded lead-acid battery (particularly in deep cycle applications).
  • is non-spillable, and therefore can be operated in virtually any position. However, upside-down installation is not recommended.

* Connections must be retorqued and the batteries should be cleaned periodically.
