what i really like about this is the "energy-full" and "energy-full-design" lines. i don't know exactly how accurate this is, but looks like i can use those two lines to get an estimate of how this battery has deteriorated.
that's important to me because i'm using a refurb laptop with a refurb battery. the refurbisher only guarantees "30 minutes of life" from the refurbished battery. so my question "is it worthwhile to buy a replacement battery" seems to be yes, I can more than double the battery life if i get a battery that meets energy-full-design.
comments?
andrew.
