IMO, no. Most of the water lost is because of electrolysis due to
overcharging. Since the electrolysis produces relatively pure hydrogen and
oxygen, the loss is only water. Very little acid is lost. And too much
acid is more of a problem then too little.
As Peter suggested, you could measure the concentration with a hydrometer;
but be sure to fully charge the battery first. The concentration naturally
drops as the battery is discharged (the sulfur ions combine with the lead
and lead oxide plates to produce electricity). It's probably also best to
run a desulphation cycle first.
