Battery life is shortened by being left partially discharged, and as such, branding any battery as good or bad, without knowing how it was treated during its lifespan, is unwise.
Batteries vary in their ideal Acceptance/Absorption voltage and there is no way that the engine computer or vehicle's voltage regulator is optimised for returning a battery to 100% charge every time, especially if the battery is discharged beyond the 0.5% of capacity it might take to start the engine.
Like all battery chargers, they are more concerned with not overcharging a battery, not perfectly recharging it to 100%, as this is impossible as all batteries vary slightly so a one size fits all charge algorithm can't be perfect for every battery, despite what the marketing departments or chargers will claim.
If a battery is discharged by running the stereo or lights, engine off, to even 90% charged, then it can and likely will take the alternator 4+ hours of driving to get the battery back up near 100%.
At States of Charge over 80%, the battery simply cannot accept very much charging current before voltage would climb to unsafe levels, so time is required to top charge batteries, and at voltages high enough to actually max out the electrolyte's specific gravity.
The cheapest quality battery which lives its life closest to 100% charged will live longer than the best quality Lead acid battery that lives its whole life 80% to 90% charged and never gets to 100%.
Keep that in mind before praising or demonizing any given battery brand/ manufacturer.
Also keep in mind modern vehicles that sit for 3 weeks can deplete the battery well below 80% just sitting while waiting for the door lock remotes, or running the alarm system and keeping the engine computer memory.
An otherwise healthy battery at 30% charged can still start the engine, and many people assume that if it starts the engine, it is fully charged.
These additional variables make typecasting any given battery brand as good or bad even more worthless.
But perhaps expelling flatulence in a windstorm would be more effective than convincing the masses of these facts regarding lead acid battery charging and care for maximum lifespan.
So much easier to see a label and rely on internet rumors.
