I often swap out batteries in my laptops. I wonder if anyone could share how to find the exact battery so I don't end up buying the wrong one on eBay or from other third-party sellers (since original parts are usually pricey, even if they sometimes exist, though I know they're great). Is there a site that lists how to get the part number for different laptop brands? I looked at Batteryuniversity and other places but didn't find any good info. What I need is some guide like "for HP batteries, look for a label starting with PN-30..." or something similar. Any help would be amazing thanks!

This tool shows data about your laptop's battery while it is working, but the link won't work like that. You also can't find a list of all the batteries here.

I used this tool on my Alienware M17 to show me what my PC's motherboard was called (using HWinfo). Since the Alienware had a website with spare parts, searching for the right model and looking up parts should take you to an HP parts page. It might not be true, but maybe HP does have a site like that, just like Dell does.

Wow, that app is the one I needed way back in the day. It's not even bad, just not what I thought I wanted when I first tried it, so thank you super!

Thanks, that's really handy! Check out parts and upgrades for your Dell computer & more. Go to www.dell.com by typing in your service tag, part number or browse there to find exact replacements for what came with your Dell. I use HWinfo all the time too. Thanks again.
