Gel Battery Advantages:
• Totally maintenance free
• Air transportable
• No corrosion
• Spill proof/leak proof
• Installs upright or on its side
• Superior deep cycle life
• Very low to no gassing (unless overcharged)
• Compatible with sensitive electronic equipment
• Superior shelf life
• Rugged and vibration resistant
• Very safe at sea with no chlorine gas in bulge (due to sulfuric acid and salt water mixing)
• Will not freeze to -20°F
• Lowest cost per month (cost / months of life)
• Lowest cost per cycle (cost/ life cycles)
Gel Battery Disadvantages:
• Higher initial cost
• Heavier weight
• Water can not be replaced if continually overcharged
• Automatic temperature sensing, voltage- regulated chargers must be used
• Charge voltage must be limited to extend life
(13.8 to 14.1 volts maximum at 68°F)
Absorbed Electrolyte Advantage:
• Totally maintenance free
• Spill proof/ leak proof
• No corrosion
• Installs upright or on its side
• Lower initial cost than gel batteries
• Compatible with sensitive electronic equipment
• Very low to no gassing (unless overcharged)
• Excellent for starting and stationary applications
• Will accept a higher charging voltage than gel batteries
Absorbed Electrolyte Disadvantages:
• Shorter life cycle than gel in deep cycle applications
• Automatic temperature sensing, voltage regulated chargers must be used
• Water can not be replaced if continually overcharged
• Charge voltage must be limited to 14.4 to 14.6 volts maximum at 68°F
