Yes, acid neutralises alkali, but there's two schools of thought on this. I prefer to not introduce another wet, corrosive chemical into the tight, awkwardly shaped cavities that are called battery compartments. Liquids can leak through holes in the compartment and find their way onto PCBs and components.
