4 or 5 years old? It is likely still in warranty: go get a
replacement. My guess is it is likely the 1A solar charger overdid it
over time. A full time battery minder/desulfator type of charger is
probably a better way to keep it topped off and healthy.

I have a 1 amp (I think) solar panel keeping it topped off and occasionally I switch it to the breakaway battery. Probably been 6-8 months since I've used it and when I did.. it died rather quickly... charging would bring it back... but again sagged quickly. The cells were a little low on water but not below the plates... topped them off and put it on a batteryminder maintenance charger...
