What is the advantages of a gel lead acid battery


  • Maintenance free; can be mounted sideways; low self-discharge
  • Long lasting due to its ability to transfer heat to the outside
  • Performance stays high until the end of life, then drops rapidly
  • Produces water by combining oxygen and hydrogen
  • Safe operation and forgiving if abused; less dry-out than AGM
  • High cycle count, tolerance to abuse and heat
  • A large variety of battery sizes available


  • Higher manufacturing cost than AGM
  • Sensitive to overcharging (gel is more tolerant than AGM)
  • Moderate specific energy and load current
  • Subject to release gases. Ventilation needed
  • Must be stored in charged condition (less critical than flooded)
