You can conclude this if you wish. However, any auto battery will eventually die, and if it does not need to have water added before that point, it is not necessary to add water. Keep in mind, that selling auto batteries is a competitive business. If a company purposely caused premature failure of their products, they would lose business to their competitors.That reads that it is calculated to put less lead in and/or create x amount of sulfation at a given point.
But it may be more or just as beneficial business wise to hide fill ports, discourage maintenance, and create premature failure for replacement.
Either way is giving the business desired result.
Unnecessary, except for continued production and profitability, premature failure.
As a point of interest, the lead in the battery grids is an alloy. Pure lead would be too soft for manufacturing purposes. The old batteries used antimony alloyed with the lead. This caused a need to add water regularly. The "maintenance free" batteries use calcium instead of antimony. This sharply reduces the need to add water.
