You must be rich to have all those AGM batteries - given the information on this thread I googled these batteries - the costs are a bit steep.

Standard flat plate lead acid Deep Cycle batteries can be irrepairably damaged if used for starting or where High amperage is required, as in winching, reason being, I have been told, is that the lead plates in Deep Cycle batteries are thinner (to get more in I presume) and high amp draws can overheat and distort the plates, occasional short starts will not harm, but it is not recommended and will void battery warrantee, Regards Frank.
