About Thinkpad's batteries.
A bit off-topic being a hardware specific question but taking in care
several people here say to use Thinkpads (and the cost of their
batteries) I think it'll be useful for everyone to share our experience.
My experience with these laptops is short, I bought a refurbished x201
in Jan 2014 and a T420, second hand too, in Sep 2014. The first came
with a *new* 9-cell lenovo original battery that lasts almost 6 hours
long as who sold me had promised me.
I received the T420 with a used 6-cell lenovo original battery that gave
me barely 2 hours. I presumed it'd give me 6 like the x201 with
a 9-cell one, so I bought through ebay a *supposed* "lenovo original"
new 9-cell battery that suddenly *died* after 15 days of use :-). The
vendor refunded me the money so the second time I bought some of those
*trade-less* 9-cell ones you find in ebay. That's the one I have in use
since Dec 2014. Initially it lasted ~4.5 hours, but now, after 7 months
of use, it lasts no longer than 2 hours.
As I told you my experience with these laptops (and laptops in general)
is short so I don't know if I wasn't lucky or those in forums that
assure these batteries can give *15 hours* did the test in suspended to
RAM state :-).
Did some of you get 15 hours from some of these batteries? If that's
true, what tech specs should I take in care at time to buy a new one?
