If a maker devoted a chapter in some manual to battery use and care, buyers might think "Is there something wrong with this machine's battery?" and sales would suffer.
Since no maker writes in length about this, they all are on the same playing field.
There's a lot written about today's batteries so I won't go on at length but the run it down advice was for the bad old NiCad batteries. Today we have LiON, LiPO and such. The rules change and the battery management in the laptops are much better. But the cycles are still low.
On the plus side I was pleased to see Samsung laptops implement a "charge to 80%" battery life extender. That 300 cycles changes to about 1500 when we do that. Of course if we just run on AC when possible we get many more years before a battery is required. We've had laptops sitting on desks with the AC on for 2 years (and longer) then we go mobile and surprised when the battery is still working for many hours.
