Hello Fam,
The battery in my Lenovo T495. Probing what peoples experiences have been with batteries on ebay. The cost is approximately a third or fourth of the price from Lenovo. Will it be a dud, explode on a plane or in my lap?
Let me know your thoughts.

For peace of mind, I just went with what I could find from iFixIt for my battery replacement.
I see yours was quite easy to find: Lenovo ThinkPad T495 Repair - iFixit. And $80 is not even twice the price of the ones from other third-party sellers.
@wwed26 Even for your smartphone, but even more so for your laptop. DO NOT ever let the battery charge past 80-85% at the absolute most. Why? A lithium ion battery has a volatge range, and the top end at 100% is 4.3volts. Not only is charging the battery up to this 4.3 volts, severely, degradibg to the battery, but KEEPING it at 100% for any length of time, is just rapidly depleting the overall charge capacity per charge. It gets worse fast every time you continue to do this.
Also at absolutely almost all costs, even in or rather, especially in an emergency situation, keep the battery charge above 30%. I can tell you for a fact that I have a laptop battery from a computer designed for Windows 8, so around 2013 or so, that the charge level gets really wonky around the 24% mark. I noticed this immediately, as I was keeping the battery between 65% and 40%.
I let it run down a bit more, to nearly what the computer said was 30-34% I don’t exactly remember, but low 30. Thst was on battery, and when I connected the charger, it then estimated the charge level at a very low, 17% charge level.
If 17% wasn’t correct from memory, I also remember seeing single digit charge levels (something I want to avoid) and just recently it has happened once more, running down the charge to 24%.
When I set Windows critical battery level to 24%, the laptop eventually went to sleep, then, after a couple hours, did a wakeup and full hibernate and shutdown. When I charged it up again, there is an orange light on the side of the computer, and it was flashing rapidly.
I don’t know what charge level that was, but when it is low enough to not power on, or that orange light stays flashing, rapidly and then after 10 minutes slows down, then a few more minutes later becomes solid (indicating slightly higher charge), then it most certainly is not anywhere near a 20% charge.
So that is a real-world example of why it is inadvisable to rundown a lithium ion battery, especially large ones, below 30%. I haven’t had issues with 100% charge and removing the chaeger. This seems to be O.K. because it is constantly dropping the voltage / charge level and not staying at 4.3 volts.
I still maintain the charge between 75% and 40% which is plenty of battery runtime for me, somewhere around an hour or a bit more. Then, I just plug in the charger when Windows has a full-screen message for low battery, at 40%.
One more thing, I have a seven-year-young phone, and of course the battery doesn’t last as long as it used to, but it surprisingly has not degraded much. Mobile data eat ear EATS battery as if it is being paud to do so, at nearly 1% per minute, and I even run a firewall and it doesn’t make a huge difference in battery drain. So it never has had great battery on cellular data. But on wifi, it also isn’t great
I keep the charge between 60% and 40% as much as possible, and don’t use any apps on it anymore, as it is up to 1,600 charging cycles now. But when I do use wifi I get maybe 40-55 minutes of use in the charge range of 70 down to 35.
That’s not great sure, but it also has 1600 charging cycles. Have you ever even kept a smartphone for seven years? Most people don’t, but android is good about keeping apps compatible, compared to iOS, and I haven’t found a single app I cannot use because of being stuck on Android Oreo. Have you even had a ten-year-used (and used heavily, but I must commend that it was not left plugged in, which has helped keep the battery in quite exceptional health) with many daily charging cycles, for years, eveb being used as the main computer) with a usable charge?
I bet not! All, and I do mean all, laptop batteries besides this one, have held about 40-50 minutes of charge time at the most. Hey maybe that’s good for a laptop designed for Windows 2000.
So you don’t have to take my grain of sand, here is battery university who has also done some tests.
I’ve always bought my replacement batteries from the cheapest possible seller and haven’t personally had a problem. Not that it never goes wrong, but you’ve got a good shot.
This is just a reminder that running a phone with no security updates for both OS and its firmware is a bad practice now. Its maybe good for just watching youtube and not much more. But then you should probably not connect it to your local network as well.
It sucks but forced obsolence also goes with security updates for the OS and firmware. Such is the world that we live in.
ios and android should be mandated 6 year lts for devices imho!
The latest Pixels are promising an 8 year update so that we may take care of our phones for longer.
That’s just 1 phone from 1 brand … needs to be from a lot more brands to make it better.
eBay is fine. Try to buy an OEM battery that has the Lenovo FRU number on it.
