I just got a pretty good deal on an old ThinkPad (think 10 years old now) to use as a beater for screwing with ArchLinux and hopefully to find a real use for. It’s in great shape like it was never really used, but big shock, the battery is at 50% effective capacity and what’s there disappears in less than an hour.
Would you bother buying a battery replacement for it? On one hand I want it to actually be usable on the go because that was sort of the point. On the other, while replacement batteries exist, I’m worried that they’re already very old themselves and already “expired”. Would you take the chance? I don’t want to let this thing go to waste when it’s still perfectly usable, in fact it’s pretty fast.

You don’t buy a genuine battery, they are indeed too old. There are third party manufacturers making new batteries for old thinkpads, kingsener and greencell are two. I have kingsener in my homelab X230(Arch) and T440p(NixOS/Silverblue) and am very happy, basically better than new(more recent battery tech).
As a Linux toy, I’d absolutely replace it. I have a Zenbook from 2011 that still works fine enough for desktop apps with Mint after a battery swap.
At minimum though, I’d open it up to make sure the battery isn’t a bloated spicy pillow waiting to blow.
I’ve got a couple of machines that I put new batteries into not long ago. If it’s solid hardware, throw Linux in there and give it new longevity.
Back when smartphones had easily replaceable batteries, like the LG V10 I bought for my mom, I bought her a new battery after 3 years and it gave it new life.
Now, 10 years is on a different time frame. Personally, I would gauge the price of a replacement battery against how much I paid for the laptop. 10% maybe? Completely arbitrary. $20 replacement battery for a $200 used laptop.
10 years isn’t really that old for a laptop. I still use my Lenovo T60 and right now I’m rebuilding the battery on a Dell with a Piii in it.
That sounds about right, now that you’re jogging my memory. I have a 2007 a Sony laptop that I eventually wiped and installed Linux. Ran so much better than Windows.
In 2017 I bought a Samsung Galaxy S8 smartphone, which ran circles around my laptop. Coupled with my laptop battery lasting about half an hour, I stopped using it.
I just googled how to rebuild laptop batteries. It never occurred to me it could be done.
If it has a removable battery, then it’s likely made up of 18650 cells. If it isn’t then it’s likely a flat lithium cell like a phone.
I pulled the battery case apart and snipped all of the 18650s out and charged them in a dedicated charger. They had been sitting too long and some of them were far below where they should be. It was causing the laptop power adapter to shut off.
Once they were properly charged they all tested good again. I could buy new cells, but I think these will work fine for what it is.
Now I need to spot weld metal tabs back onto the cells, put it back together, and hope it works.
Depending on price I might go for it
I did spend like $40 on a battery for a 10 year old laptop a few years ago so that I could keep using it for troubleshooting a remote network I setup up awhile ago because it’s cheaper than a new laptop.
Personally I’d see if you can find a new compatible battery not necessarily an OEM battery though as being new it’s probably going to last awhile.
How would you know if it’s actually new, though? I’d assume even third-party replacements have been sitting on a shelf for years.
It’s really just making me think that laptops are terrifyingly wasteful and I’ve been right to not bother owning one.
just open the battery you have and replace the bad cells
What kind of terrible advice is this?
Absolutely do not start ripping apart your old laptop battery to replace cells if you don’t know what you’re doing. Depending on the battery size and type, you might also not have many cells at all to replace.
You would be better off buying a cheap replacement battery, especially if it’s already 10 years old. Any cells that aren’t bad today will likely be very soon.
Telling people to pop open a Li-Ion battery is asking for a fire.
Do you work on laptop batteries often?
What does that have to do with anything? You gave dangerous advice to someone with unknown skill levels for handling batteries.
But yes, I do, and if you don’t know what you’re doing and puncture a cell trying to take the wrap off, you’ll have a bad time. Li-Ion fires are terrifying, and it makes no sense to replace a few cells when you can just get the whole damn battery for a few dollars more and mitigate the risk of burning down your house.
You do? So what’s a laptop battery then?
The fuck kind of question is that? Not going to entertain an uneducated troll.
Now you’re projecting.
I’m betting you haven’t opened a battery pack in your entire life. Why not go watch a couple of videos on laptop battery packs, what’s in them, and how to fix em? Maybe you’ll learn something instead of foulmouthing and fudding.
Me? I work with 18650s every day, protected and unprotected cells; I charge em, I fix em, and I know it’s pretty hard to puncture em; that being said, if op is anything like you he’s probably much better off leaving it to a qualified repairman or just buying new.
But thanks for the heads-up, I’ll add a safety warning to my advice; that better? 🙂️
