Lead / Acid batteries still work the same as ever. The trend has been to hide the cell covers ("It's sealed") so unscrupulous mechanics can increase sales, and that creates a market for battery "remanufacturers". If you mean by "get with modern times" trashing products as soon as the new gizmo smell wears off, that will never happen. Nor will it if you mean that one should learn to accept scams.I think you are stuck in the past..I knew that when you said remove the caps on the battery and check with a hydrometer....That was then..get with modern times Sir...J
