And here are other guidelines for prolonging lithium-based batteries.
I'd say with 95% confidence the person from Sony was either misunderstanding what you wanted to know, or was just plain wrong. |
I'm going by the Vaio care software that came with my computer. On keeping the battery 50% charged and on AC power it says "Battery life will be about 50% shorter than the one of the fully charged battery, however, this mode prevents battery degradation and is more effective if you usually use the computer with the AC adapter." So I just do what it tells me.
I'm going to check out those links too, thanks for that info.
