Welcome aboard and congratulations on acquiring a superb notebook.

You can go the China 2560P/2570P clone batteries available on aliexpress or ebay as a cheaper alternative to the HP ones. Problem there is the cells will be substantially worse quality,have lower capacity and the battery itself will diminish in capacity much sooner.

Your system will probably come with a 55Wh or 62Wh 6-cell. I'd advise perusing the battery life and weight reduction tips linked from the opening post. You may be able to pickup some simply strategies to extend your working time with the existing battery at little or no cost.

Thanks, yeah it looks like it comes with a 6-cell. Has anyone tried replacing the cells in a HP battery with something like a panasonic NCR18650B (3400mah)? I've seen this done for lenovo thinkpad batteries (and considered doing it myself before coming across the 2570p). This could result in a 3 cell 37.74Wh, 6cell 75.48, or 9 cell 113.22Wh battery...

I've just joined the 2570p party and bought one off ebay (although it's taking its sweet time to arrive).

I'm interested in acquiring a 3-cell battery that doesn't protude from the back of the laptop (I do most stuff plugged in but like having it as small/light as possible when moving it from place to place). Also possibly a new 9-cell for when I do want extended battery life. I've had a google and found the usual cheap 6 cell ebay/amazon options, and i've seen the HP new options which cost about what I paid for the laptop.

So, my question is: where do you good folks buy decent 3 or 9 cell batteries for the 2570p?

I'm not sure if I'm allowed to post this here, but I've upgraded my laptop and so I'm selling my external GPU.

I've been using it with my HP Elitebook 2540p, and it's been great for gaming. It uses the PE4H adaptor with a 34mm expresscard.

$120 USD

I can sort out shipping to most places, or a discount if you pick up (Christchurch, New Zealand).

Technical Details:

• Internally this uses the hwtools PE4H adaptor
  
• It's a Nvidia GTX560
  
• 34mm expresscard
  
• The enclosure is a laser-cut box that I designed
  

Sale includes:

• Enclosure
  
• GPU
  
• Power brick & cables
  
• Mini HDMI cable
  
• Express port adaptor
  
• Original GPU user guide & documents
  

Paypal is probably the easiest option for payment, but I'm open to other alternatives such as a bank wire transfer or Bitcoin.

Obviously you'll need to check that your laptop is compatible, but if you're on this forum you've probably already figured that much out.

I'm happy to answer any questions .

Hey, is this for sale still by any chance? By co-incidence I happen to actually be in Christchurch NZ... so could pick up/pay cash.

I've only just started looking into eGPU's but I think from what I've read this would work with my lenovo t410 (34mm expresscard).
