Any way / software to check how long laptop battery can last without waiting for it to drain

My corporate office has one Lenovo X220 but nobody knows if it's
been used for how long by the previous owner.  They also offer
Dell E6230 laptops.

I'm choosing between one of the two but first I need to know
how long the battery will last (as previous owner(s) had used them
before).

Q1:
Windows 7 power meter usually doesn't give a good gauge.
Is there any tool / software that I can install to gauge for the
laptop I'm going to choose/collect, how long the battery will
last on full charge?

Q2:
Assuming it's brand new standard battery (6 cell ?) for both
X220 & the Dell E6230, which of them would last longer?

Thanks.  Does it take very long to run to generate the report?
Whole idea is not to fully charge the battery

And we all know how well windows "Guesses"!!!

One of my kids laptops has 3 hours remaining 10 minutes before it shuts down.

Forget any windows estimates on a battery of unknown state.

what kind of battery does the laptop have this has a bearing on its charge capabilities

Well, I have to choose between a Dell E6230 & a Lenovo X220 from
our corporate office & I guess they're both used before by some
other staff.

The officer in charge of the laptops only allows me about 5-10
minutes to take out the laptops from the store room to test
them, so I really don't have the luxury of fully charging up
both laptops to the full to determine which of the two has
better batteries.

It's crucial for me to have a longer battery operational hours
because I often went to places where there are no AC power
supply to charge up the batteries.  Certainly I can spend my
personal money to buy spare battery but it's not worth it to
spend my own money for work purpose.  It's difficult to
justify to my management to buy such things (even if it's
consumables)

if you explain that to the guy in charge, he may let you test

Both the X220 & E6230 comes with 6 cell battery.

The E6230's battery is 58Wh Type J79X4 ; not too
sure about the X220's.

What I like about X220 is the keys & the edge of
the laptop are rounded (not too piercing on the
palms) while E6230's keys are rather hard to type
on with sharp edges.

However E6230 comes with two USB 3 ports while
I doubt the X220 which our corporate buys has
any USB 3 port (wanted USB 3 for faster backups
& when I map an external USB 3 HDDs to other
server, it's faster)

Both comes with 7200rpm HDDs:
X220 has   Hitachi HTS725032A9A364   while
E6230 has  Seagate ST320LT007-9ZV142

Once again.......
If you have no way of knowing the actual state of the battery, and you wont do in ten minutes, then you have a lucky dip.  Either battery could be dead in a week, you have no way of knowing in a five/ten min window.
