Reddit reviews Lenovo Lithium Ion ThinkPad Battery 68 + ( Manufacturer P/N ; 0C52862 ) Extended Run Time 6 Cell System Battery, 72Wh, 10.8 v, 0.74 lbs

Maybe consider a Thinkpad. The T and L series are mil-spec tested so they should handle dust pretty well. They also have external batteries so you can bring a few extras to extend run time. Some models can also be configured with LTE if you need internet access in areas without wifi.

I'd recommend the L470 configured with the extended 72Wh battery, then spending the remainder of your budget on extra batteries.

EDIT: The T470 with the 61++ batteries is a good option as well.

Amazon 60 to 65$ OEM battery

Unfortunately, 72wh is plastered all over the description.

Thanks for the help...I requested a return.

Right here

Was $50 when I bought it, however.

This is what I would buy. Not as cheap as any of us would like, but not as expensive as Lenovo either. Also, I've bought batteries on Amazon before (for around the same price) and they were pretty legit.

I can confirm the Amazon sold only by "Liquid Power" is the real deal

> sceptical about it, as these batteries must have degraded over time

$69 will get you a brand new HIGH CAPACITY battery so just figure that into your calculations.

Batteries are expendables so expect to replace them over time.

HTH.

I bought a 72WH 68+ Notebook Battery 0C52862 from Amazon. The seller was price master jay.

That's correct. This is the battery that I upgraded to.

Thanks, that's very helpful!

If that's the only advantage of the 470 I certainly don't care much for it, since the laptop obviously doesn't come with a 4K screen and I won't be plugging it to a 4K TV anytime soon.

Someone also told me that the T470 comes with a USB-C port. Which could be nice to have, but... even if smartphones use the C port now, I honestly don't see much use for it. Most chargers still come with a USB-A to C cable anyway, and other than that, I'd rather have more USB-A ports so I can plugin my work peripherals (webcam, headset, etc.) than have one less A port in favor of a C port.

Also, thanks for highlighting the differences between the T and the L model... it seems I underestimated them. Unfortunately I probably won't have much say on it, but at least I can try asking for a T460 if they're available.

Now that you mention it, I think people who receive an L460 are getting it with a weird "hump" below it that servers as battery extension. Probably this one.

It's damn ugly but I'm wondering if you would get better battery life with a "humped" L460 than a naked T460?

Finally regarding graphics, where does that difference come from? In the spec list in Lenovo website both are listed as carrying the Intel HD 520 integrated graphics?

Again, thanks a lot for your support, really useful!

No? Lenovo lists the 68+ as $139.99 USD on their webstore.
Here, have an amazon link for $71.10 (time of post) http://www.amazon.com/Lenovo-Thinkpad-Extended-Battery-0c52862/dp/B00KOHS6UK

And lastly, your battery could just suck.

Amazon has it right now for $70, which is one of the best prices I've seen.

The touch pad isn't really all that bad, especially if you use the touch functions.

As for the battery, mine came with that battery but they are pretty easy to find. Amazon has it for sale but it's a little pricey. https://www.amazon.com/Lenovo-Genuine-Extended-Thinkpad-0C52862/dp/B00KOHS6UK

I prefer Amazon, as the reviews are of the actual product AND you can look at the seller rating also. Genuine Lenovo for $61.45. Third party but 5 star reviews for $35.

I have one i bought from Liquid U.S.A on amazon with a mid 2018 production date. While it has performed as expected i'm not completely sure it is a genuine lenovo battery.

You could also simply buy one directly from lenovo.

This should fit it.
