Buying a battery for an old laptop

[Ha-Satan]

So I have a Dell Latitude E5440 with an i5-4200U. The battery seems to be on its last legs, which is to be expected considering the laptop is 12 years old. I only get a few hours of charge when doing basic tasks and lately it seems to not even hold a charge properly when totally powered down.

 

The laptop itself still works great and I would prefer not to replace the whole thing, but I'd like to replace the battery if possible. The battery in question is a CXF6641.

 

It doesn't look like you can buy this model of battery any more straight from Dell (which is understandable). There are a lot of ebay listings for supposedly compatible batteries but they mostly look dubious to me.

 

So my question is, do any of you know of a good trusted source for batteries for older laptops?

Newegg sells this battery here, it seems like it is the right model for your device. Best bet on this sort of thing is to dig a little on Amazon, find some model numbers, and look those up on trusted storefronts. That's worked for all of my projecting needs for as long as I can remember. Granted, this may not work so well for more obscure parts, and I was honestly surprised it took me as brief a time as I did to find this.

What are some trusted sellers you've had luck with in the past?

 

I ask mainly because a couple years ago, my mother-in-law bought a new battery for her Dell laptop from one of these Amazon third-party sellers, and even though it listed support her model of laptop and was physically compatible, it ended up being bad and fried her laptop. So I am a little gun shy about buying one of these from a random third-party seller on Amazon or Newegg without a specific recommendation.

Ooh.. Thats a hard one. I get your concern with your past experience, but I so often just go with the third parties. I think that MicroCenter and iFixit, but as seen in this case, not everything is available in those places. I often find digging for a lot longer will find more reliable results, as I found on this site, recommended by someone in the higher-ups of the Dell Forums.

 

The TL;DR is to dig a bit longer to find things like this recommended here on the Dell Forums.

Hmm, that's a tricky proposition. $80 is a bit of a tough sell when I could just get a whole-ass replacement laptop for not too much more than that (considering I only paid $130 for this laptop back in 2021).

 

Thanks for doing a little digging, I appreciate the help.
