Nothing annoys me more than product packaging that is plastered with meaningless phrases like "sustainable" or lists an array of products that the batteries could be used in, but doesn't have any specs.
Ryobi has a "40v" line of products. It's not 40v because that's just a marketing gimmick. Since we don't know what voltage it is, we can't calculate the total energy using advertised Ah (can that figure be trusted, or is that a gimmick too?).
I went to the Ryobi website looking for the specs on Wh, and there was a wall of words, but no mention of voltage or total energy. The site advertised that if I had questions, I could chat, so I did. I asked how many Wh were in the 40v 6Ah battery, and the rep said the battery could last 20-30 minutes.
The rep asked if I had any other questions, and I said yes, I was hoping to get product specs. I was given this link to "specs", which contains no specs.
Ryobi not-specs
So the most relevant information about a product like a battery can't even be determined unless you buy it and perform the test yourself.
Why is humanity so stupid and easily distracted that you can sell more product by talking about everything except the relevant specs for which you'd base a purchasing decision?
Don't get me started on zero calorie energy drinks that contain no energy.
