Frequently Asked Questions
What is special about ODYSSEY batteries?
ODYSSEY® batteries provide double the power and triple the lifespan of traditional lead-acid models. Odyssey batteries are designed to handle up to an 80% Depth of Discharge (DOD), especially their AGM (Absorbed Glass Mat) models. This means you can safely use up to 80% of the battery's total capacity without significantly affecting its lifespan. They are ideal for diverse uses and performance needs, ensuring reliable support wherever you go.
What type of battery is an Odyssey battery?
Odyssey batteries are Absorbed Glass Mat (AGM) batteries, not gel or Ni-Cd. They use absorbed electrolyte technology, meaning no free acid is inside the battery.
How long does an Odyssey marine battery last?
Odyssey batteries can last up to 10 years, which is two to three times longer than conventional lead-acid batteries.
How should I store my Odyssey marine battery during the off-season?
Fully charge the battery, disconnect the negative cable, and store it in the boat or a cool, dry place. If fully charged and disconnected, Odyssey batteries can be safely stored for up to two years.
