That's just ONE of the problems of HD batteries in parallel, a cell shorts(***) in one, the good, FULLY CHARGED parallel battery rapidly discharges into the ~10 volt HD battery.
*** Very common lead-acid battery failure mode.
2 batteries in parallel, if one battery has a cell that shorts, there is a lot of current and a lot of heat. Its only a matter of time before it goes poof.
