Evil Spirit, Fred is correct, if the battery is in the factory location. ALL batteries are temp sensitive. Each have thier limits.

Gregsdart, Your thoughts on a fix would increase the life of your battery but using one charger like Crizila or Todd should do the same thing. Most "Smart" chargers have AGM charging abilities and can fast charge.

Rickster, the odyssey is also an AGM. They chose to use flat plates instead of a lead coil design. The term "dry" can really be used for all AGM batteries as there is no free flowing fluid. I avoid that term due to the fact there is a type of battery that IS truly dry. It has little more than lead and calcium powder.

All of the batteries mentioned are great! As I said earlier, every battery is built with a specific purpose in mind. In most cases, the battery that everyone is currently using will continue to "do the job". Battery life is my real concern.
