I guess the downside of AGMs is the price however there are plenty of upsides starting with the length of service life which should be 2-3 times that of wet cells. There is NO checking for levels on an AGM. There is no concern about venting. The only checking to be done is perhaps connections at the battery. You can locate an AGM anywhere you please. They don't even have to be mounted upright. Mount them INSIDE if you wish. In boats it is not uncommon to find AGMs located in spaces inside the cabin. They can withstand a deeper discharge, & recover, than a wet cell. They accept a bulk charge rate better than a wet cell. They lose less charge in storage than wet cells.
Yes, the wet cells are cheap on the initial setup but over time are they a better way to go? My first AGM, a 4D case size, had a 215AH rating & gave a service life of 9 years. Every year it sat in storage for over six months with NO trickle charge or top up charge.
