Your first question has been answered by user user1757436.
I'd like to add something to your second question. First of all, your page is all good and designed nicely. Secondly, contrast is definitely a very important aspekt of web design.
Should you worry about the results from the test of checkmycolours.com?
a, checkmycolours.com
There are many errors ...

CheckMyColours.com uses the Web Content Accessibility Guidelines (WCAG 2.0) contrast tests.
The validity of the tests is something to bring up with WCAG rather than checkmycolours.com.
I am unaware of the WCAG providing the research supporting their contrast ratio standards. However, my experience with those standards is that they are fairly lax. I've ...

I've always found out that only reading and asking others is not going to help. The best thing is to read about the split testing, see what works for others, then try it yourself. And don't try only 2 variants, because you definitely aren't going to find the best one out of two. Do it continuously until you fail to improve anymore.
By doing split tests I ...

Given that the life of the battery is so long, I don't think that there is a value of displaying a middle display.
Orange tells the user that there's something that they probably want to address, but they don't need to do it immediately. Red tells the user that there is an imminent problem that they need to address soon. With a 2-day battery life, if ...

I would suggest (for laptop atleast) keeping it as follows:
Green 40-100%
Yellow/Orange 20-39%
Red 1-19%
The reason being, I have read many articles which suggest keeping your laptop charged between 40-80% to increase the battery's life. One such article.
I know some manufacturers which go for a wider green band:
Green 20-100%
Orange 8-19%
Red 1-7%

The colour indicator is used as a priority status:
Red = urgent.
Orange = weak warning.
Green = good.
The priority depends on the application and the consequences of a low charge. For something like my kindle where the battery lasts for a month or more at a time, 10% isn't yet an urgent battery level. But for a backup UPS in a hospital, a charge level ...

No right or wrong here, but you need to convey a message to the user when something is about to happen. Green for OK battery ranging down to 50 %. Then we want the user to be more careful with battery so 20-50% is represented by yellow. Last when we're really low on fuel - 0- 20% we want to show the user it's close to nothing in red color. Now you need to ...

You should clear both password and username, or neither, your choice.
Clearing one but not the other can get a hacker/cracker ideas about where he went wrong (he may well be guessing the username as well).
For the same reason you should never state which of the two is invalid when authentication fails. Instead of "invalid password" or "unknown user" give as ...

Looking at this question from another angle may be helpful. A saved failed password isn't very useful. At least if you trust the most up voted answer to my question: Why do users erase all the password when they hit one wrong key instead of just the last wrong character?
The first one you mention yourself, it's an automated process. It's easier to ...

In most of the websites I have seen that use disabled buttons there are clear distinction between active and disable. There is no predefined rule that grey means disabled, usually something that is disabled simply changes opacity, even browser default buttons change opacity. I think it is clear to your users that these buttons are clickable.
Google is a ...
