batteries in notebooks are using 18650 batteries (industrial li-ion)
lookin at specs of your notebook/battery its using 3 cells
which means 3 of those batteries are inside
best u can find would be samsung 3600mah (samsung 36G 18650)
its high quality battery (can feed continuously up to 10A (120watts with 3 cells))
www.imrbatteries.com

Samsung 36G 18650 3600mAh 10A Battery

Shop everything 18650! Rechargeable Lithium-ion 18650 Batteries, Chargers, Wraps – for custom battery packs and more! Popular brands for 20700, 21700, and 26650 battery sizes available.
www.imrbatteries.com www.imrbatteries.com
3 batteries would cost ~20$
if u never worked with li-ion before, better get somebody who knows whats doing, its higly explosive when it shorts
there are companies who can replace old batteries (cells) with newer ones (not really cheap)

here some video

1000mAH is pretty low. Definitely won't run your laptop for six hours, and it's not even enough to run most phones for six hours of screen on time. I don't think really any power bank can do this besides a UPS. These power banks are designed for phones, and most of them can't even charge a laptop, since they don't have an appropriate port or can't supply enough voltage/current.

It is 10000 mAh, not 1000 mAh.

10000 mAH isn't much either. It just means it can provide 1A for 10 hours.

There's no method to hook this up to your old laptop, so it doesn't matter how many mAH it has. You can't charge your old laptop through a USB-A port, nor does it have a USB-C output that requires a very new laptop.

Something like this is what you're looking for, not a skimpy little power bank intended to charge a smartphone.

Probably a bit too much for just six hours, but that begs the question: Why do you need an external battery to run it for six hours doing word processing? Is it really old and has a faulty battery? If that is the case, you would be better off with a new laptop than spending more money on these solutions. If it's new and just has a really low capacity battery, you could probably find battery upgrades, or just buy a better laptop.

It might be too much, but without knowing the laptop or the exact work, it might not be! You should see how quickly my laptop eats power when I'm running a Monte Carlo simulation or something.

There are special powerbanks designed for laptops (50000mAh and more), but they are bulky, and expensive. If you really need six hours of laptop time, as said above, better get new laptop. Your old laptop is most probably power eater anyway, requiring more power to do the job than necessary, If money are tight, even new Android tablet will do the job.

I believe the original capacity of the laptop battery was 3300 mAh (likely manufactured sometime around 2014). The battery isn't faulty, but it has aged like any other low capacity battery over a period of six years.

My workplace requires me to use the laptop they provided me. I could replace the internal battery, but I can't imagine that the laptop is able to fit a battery with the capacity to power through my schedule. Even if I could do that, my workplace wouldn't allow me to replace the battery.

I should also mention that the laptop has a dual-core SoC.

In that case youre probably better off using what was suggested above.

You should probably submit a work order for a new laptop to your employer if you have one and inform them you can't do the required job with the equipment they provided.

My workplace is on a very tight budget (due to the coronavirus) and the IT professional had to be laid off a while ago (also due to the coronavirus). As a result, there isn't too much my workplace can do. They issued the same kind of laptop to a ton of my colleagues (including me). My workplace is also heavily considering having us work from home (the laptops were bought as a precaution). Revenue (in general), salaries, and wages are tanking.

In summary, the coronavirus is beginning to severely cripple and hurt my workplace.

Not to pry but why don't you have plug sockets where you work? The bulky units are effectively battery banks with an inverter.

Some of our "offices" (especially the tiny ones) don't have more than one plug socket due to major constraints.

It's a really bad situation you're in, but it's either spend a lot of money on one of those bulky power banks linked above, bring a power strip to plug into the (hopefully) one power socket in the office, or ask your boss if you can work from home.

Both power sockets are full. 🙁

Again, my boss is considering having me and my colleagues work from home. I don't know the maximum amount of battery capacity the laptop is able to handle. Could someone do some digging for me? If bulky power banks won't work, I'll have to replace the battery.

Your laptop is the X200MA from the "Best SSD for longevity" thread?
If so, I can only find 2200mAH (24WH) batteries for it.

That's correct.

I did find a 3300mAH on ifixit's site along with instructions for replacement, but I doubt there's anything higher. https://www.ifixit.com/Guide/Asus+X200CA+Battery+Replacement/98636

Do you have admin permissions? If so, I'd suggest running command prompt as an admin and doing a battery check: https://www.howtogeek.com/217010/how-to-generate-a-battery-health-report-on-windows-8-or-windows-10/ Your current battery may have actually gone down in capacity after repeated use over several years.

When using an external power bank the mha of the original battery is fairly meaningless, you need to look at the Wh. The laptop will be using a much higher voltage batter than a regular power bank. As you don’t have a USB-C charging input a regular power bank is useless to you.

Something like this might work https://www.amazon.co.uk/NOVOO-Port...93S2SJ723VA&psc=1&refRID=46MC58Z4G93S2SJ723VA but it’s only 60Wh and you would be lucky to get 40Wh of actual power to the laptop after all the efficiency loses that are involved.

battery capapacity on USB poewerbanks isnt same as capacity on notebooks
even if its using same li-ion batteries

USB powerbank u linked has 4x 3.7V 2500Mah batteries inside (10000MAh @ 3.7volts)
if u convert it to voltage u need (3.7v * 3 = 12.1V = 10000MAh /3 ) u will get to 3333MAh, there is some power lost during voltage conversion, so around 2800~3000MAh should be real
thats ~36WH
if your notebook eats 33watts, it will drop dead within ~60minutes

Where could I buy a new (and genuine/reputable) battery for the laptop?
