At the beginning of each season some of us realize that our tires or batteries should be replaced for peace of mind . Especially those of us that are dry campers who go down gravel roads and do not ...

It is not hard to find other AGMs with fast charge specs.
Per the Enersys(Odyssey) Technical Manual:
On page 17, please observe 'Table 6: fast charge capability' where it can be seen that an Odyssey can be charged to 100% in 30min at a charge rate of 3.1c10.
For example, the ODYSSEY ® 31-PC2150 battery is rated at 92Ah when discharged at the 10-hour rate (9.2A for 10 hours).
Using the above spec, this battery can be 100% charged in 30min at 3.1 x 92 = 285A at 14.7V with temperature compensation.
Another mfgr is Optima which has a temp comp fast charge spec of 15.6V at unlimited Amps so long as battery temp is under 125F, switch to float when accepance current reaches 1A.
