Not necessarily, but it is possible to damage the internal connections sufficiently to render the battery useless. Our warranty applies only to manufacturing defects and workmanship issues; the policy does not cover damages suffered due to product mishandling.
While the answer to the first part of the question requires a detailed response, the short answer is that the extremely high purity (99.99%) of our raw materials makes our product very special. The technology is not new; the sealed lead recombinant technology was invented and patented by us back in 1973.
The cold cranking ampere (CCA) rating refers to the number of amperes a battery can support for 30 seconds at a temperature of 0°F until the battery voltage drops to 1.20 volts per cell, or 7.20 volts for a 12V battery. Thus, a 12V battery that carries a rating of 600 CCA tells us that the battery will provide 600 amperes for 30 seconds at 0°F before the voltage falls to 7.20V.
Yes, a transformer/rectifier can be used but it must be DC using a REGULATED power supply holding a minimum of 13.6 volts to maximum of 13.8 volts. This voltage is equal to the 'float' voltage that an Odyssey EPS battery charger supplies. Higher voltage (say 14.8 as used under a boost charge) over a period of hours will shorten the life of the battery considerably. Voltages higher than 14.8 will overcharge the battery in a short time and damage the battery beyond repair. This may include the bulging of the case itself.
No, the ODYSSEY is NOT a gel cell. It is an absorbed electrolyte type battery, meaning that there is no free acid inside the battery; all of the acid is kept absorbed in the glass mat separators. These separators serve to keep the positive and negative plates apart.
The key difference between the gel cell and the absorbed glass mat (AGM) cell lies in the fact that in the AGM cell all of the electrolyte is in the separator, whereas in the gel cell the acid is within the cells in a gel form. In fact, if the ODYSSEY battery were to split open, there would be no acid spillage!
