T480 battery size and weight

2018-03-05, 21:42 PM

I am considering the T480 as my new laptop. The rear battery options are not entirely clear to me and I would like to make the right compromise between battery life and size/weight.

 

There are 3 options:

 

24wh

48wh

72wh

 

The last one is noted as cylindrical so I assume this will stick out on the back. But what about the 48wh battery, does that fit inside the laptop? And what are the weight differences?

Solved! See the solution

Hi,

 

I'm not getting anywhere trying to find battery dimensions - or even part numbers :(  The base spec should help with the weights.

Hi,

 

I cant find weights or dimensions either BUT at the below link on the left side of the page under "commodity type" choose rechargeable batteries.  On the left side you will see the 72, 48 and 24 watt hour batteries with pictures.  Also will show part numbers.

Thank you both. I checked the pics and specs. It is my conclusion that the 48 wh and the 72 wh batteries have identical form/size and weight (form/size from pics, weight from psref).

 

It seems the batteries are identical to what is on the t470. If anyone has the larger batteries, it would be nice to have a confirmation of above and to know the extra height it gives the laptop.

 

Thanks for you help.

I confirm that I just bought T480 with a 48Wh thinking it will be flat but it is cylindrical and therefore more thick than the T480.

Is the T480 24wh battery the same as the T470 24wh battery?

Yes the T470 and T480 batteries are the same and interachangable.

 

For those who care I have used a precise nutrional scale to weigh the T480 components. Note that my model has the MX150 dgpu.

 

  • T480 without the external battery = 3.3 lbs
  • T480 w/ 24wh battery = 3.59 lbs
  • T480 w/ 72wh battery = 4.03 lbs
  • 24wh battery alone = 0.295 lbs
  • 72wh battery alone = 0.7319 lbs

The 72wh battery does had a noticable heft but I only notice it when I am holding it like a dinner plate. I don't feel the weight on my lap or in a backpack. I also no longer need to carry my power adapter since the 2 spare batteries can easily get me through an entire work day, or perhaps even 2! I don't have the 48wh battery, but I believe it is the exact same size but may be slightly lighter than the 72wh battery. The size of the battery is quite acceptable and doesn't bother me at all. It doesn't make the laptop feel or look chunky.

 

Visually the 72wh battery does not look unsightly and remains quite hidden/out of sight. I actually think the laptop looks better since it appears as if it is elevated/floating above the table. This also creates better airflow and a more desirable typing angle.

Nice pictures, it looks like something out of an advertising photo.

I like the view that shows how much the battery makes the unit stand up. It doesn't look like it sticks out the back either, and probably makes for a nice handle while holding it... It seems like mine has more cords and looks more unorganized than your setup. Sorry for going off topic. 

 

Did you notice that the TB dock gets pretty hot on the bottom? Mine is. Don't know if that's normal or not.

 

thanks for the pics and specs

Yes I try to keep a clean setup. Helps me to work more effeciently.. Here is a pic of my setup before I got the T480:

 

I also checked the bottom of my TB3 dock. It is slightly warm, but definitely not hot.
