Shield do an 88 A/h type 421 battery. There is no drawback to fitting a higher capacity battery other than cost. If you want these batteries to last, trickle charge them when not in use.
n.b. I'm not sure how you buy these now, they were supplied dry in the past with acid in bottles to fill them yourself. New regs now in force prohibit this.
I think it's pretty normal though for a battery to bubble slightly when charged - that's why they are vented. Is that the only reason to change it?
8A charge is about as much as you'd want on an A7.
