Hello everyone,
I was wondering what does "WHr" stand for when it is used to describe laptop batteries.
Here is a Dell link to batteries:
http://accessories.us.dell.com/sna/category.aspx?c=us&category_id=6590&c s=04&l=en&s=bsd&~ck=anav&p=3
See how it says 85 WHr, 48 WHr, 56 WHr before the battery names? What does it stand for? And does anyone know what it converts to in terms of actual battery power and consumption?
I know WHr is a system or scale to show the power of the batteries. The higher the WHr "rating" then the more powerful and heavier the battery.
But I find no information at all about what WHr stands for anywhere.
EDIT:
Bah, I found out something on the Dell website. Here is an explanation:
But is there anyway to convert the said ampere hours or Watt-hours to like normal time?

OK thanks everyone.
@RoShamBo
Yes, your right. It comes down to 2-3 hours and sometimes 4 hours of extra battery life.

Always buy an extra battery pack, and the AC Adapter.
