What are the advantages and disadvantages of both types of sealed valve regulated batteries?
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 • Compatibl
