Are these Ni-Cd batteries? Why doesn’t somebody make these in Ni-Cd? Wouldn’t they charge faster with Ni-Cd?
A. No, the ODYSSEY battery is NOT a Ni-Cd battery; it is an absorbed (starved) electrolyte valve regulated lead battery. In general, nickel cadmium batteries are much more expensive to manufacture and recycle, so they are far less cost effective than a lead acid product. A nickel cadmium battery would charge faster than a conventional lead acid battery; however, the ODYSSEY battery is NOT a conventional battery and its charge characteristics are somewhat similar to nickel cadmium batteries. In fact, with a powerful enough charger, it is possible to bring ODYSSEY batteries to better than 95% state of charge in under 20 minutes! That is very comparable to the fast charge capabilities of a nickel cadmium product.
