Gel (or Gelled Electrolyte) Technology

Gel batteries are classified as a valve regulated lead (VRLA) battery, which uses a one way pressure relief valve system to achieve a “recombinant technology” that never needs watering and should never be opened.

What is Gel Technology?:

a close up graphic interpretation of gel electrolyte

The electrolyte in a Gel battery is permanently locked in a highly viscous gelled state instead of the traditional liquid form. Because there is no liquid-type electrolyte, it will not leak out of the battery if tipped on its side. The thick, gelled electrolyte and tightly packed plates also protect the battery’s power producing components. Gel battery designs have a superior deep discharge resiliency and can deliver two to three times the cycle life of an AGM product in the right applications.

Advantages Over Regular Flooded Batteries:

  • Higher tolerance against damage from deep discharge. (Optimized amounts of electrolyte (which is also referred to as “acid-starved”) allows the battery to use the power in the acid before the power in the plates. This minimizes the destructive nature of ultra-deep discharges. Ultra-deep discharging is what causes plate shedding, which can destroy a battery.)
  • Longer service life with superior cycling capability.
  • Superior vibration resistance.
  • Superior protection against plate damage from
    extended power draws.
  • Lower internal resistance for quicker power flows and faster recharge rates.
  • Slower self-discharge rates for better off-season storage.
  • Safer operation from spill-proof, leak-proof design which protects people and equipment, and enables installation in virtually any position (upside down installation is not recommended).
  • Maintenance free, never-add-water design.

Applications For Gel Are Many:

Deep Cycle, Deep Discharge

  • Commercial deep cycle applications.
  • Floor scrubbers.
  • Golf Cart/electric vehicles.
  • Marine trolling, sail boats.
  • Marine & RV heavy duty house power.
  • Personnel carriers.
  • Portable power.
  • Village power.
  • Wheelchairs/Scooters.

Standby and Emergency Backup Applications

  • Cable TV.
  • Computer backup.
  • Emergency lighting.
  • Renewable energy (solar, wind).
  • Telecommunications equipment.
  • UPS (uninterrupted power systems) requirements.

Why East Penn Gel Technology?:

Extensive research and development has allowed our company to design and incorporate several key design features that collectively create a superior product which provides highly efficient energy storage and power delivery solutions across a variety of markets.

East Penn’s gel products are recognized within the industry as the highest quality gel batteries available in today’s marketplace.

Several key design features account for this:


    One way, pressure relief valves maintain correct internal pressure for optimum performance – valves are UL recognized and 100% tested.


    Exclusive gel formula and proprietary computerized gel mixing operation that ensures controlled temperatures and homogeneous consistency for unequalled life and performance.


    Multi-staged filling and vacuum operation fills and vacuums each cell several times to ensure complete evacuation of air and complete gel-to-plate contact, with before and after weights compared to ensure proper gel levels.


    Dual layer separators which lock active material onto plates to prevent capacity degradation and allow the gel to reach the entire surface of the plates.


    Specially designed polyester fibre sheets wrap around the edge of each element (group of battery plates) to prevent “mossing” (plate growth) as batteries age.


    Heavy duty grids are designed for maximum durability in demanding deep cycle applications.

AGM vs. GEL - Which is Better?:

A Gel battery is better suited for super-deep discharge applications, which means it can withstand deeper discharges without damaging the battery’s performance. However, due to the physical properties of the gelled electrolyte, Gel battery power declines faster than an AGM battery as the temperature drops below 32ºF (0ºC). AGM batteries excel for high current, high power applications and in extremely cold environments.  AGM batteries deliver a better dual purpose solution for a combination of starting and accessory power.
