Try to run it down as much as possible with the system idle. Plug in, recharge fully, repeat.

This should let the battery "learn" how much it's supposed to hold.

Sounds like your battery (probably not an OEM replacement) isn't able to provide full capacity under load once it discharges slightly. You can limit CPU power in Windows power settings to only use 50-70% of CPU power available to it, which on some computers, will make the battery last longer.

No, the issue with storage will not effect the battery.

Candydot is correct.

Run the battery down to flat ... charge it ... run it down agin.

If each time you do this the battery full level is higher then the battery is getting conditioned and properly charged.

Remove the battery ... run it on the charger ... then (CAREFULLY) pop the battery in while it is running.

Yep. Hence why I said to run it down with as low load as possible.

Long story short it's just a defective battery. You can sometimes nurse it back to behaving, sometimes not.

It has nothing to do with the hard disk being full, but that will slow down your system otherwise.

Yep ... after charging it when you popped the battery back in.

See it should last longer each time.

If the battery has any kind of warranty policy on it, return it.

If it doesn't...you're out of luck and need to look around for a more reputable rebuilder/refurbisher. There are usually reviews on most of them.

Well obviously it isn't.

It's not the computer, it's the battery.

Which is exactly why the battery is defective. The cells are maintaining voltage but are failing to provide the necessary amperage to keep it running at the power level that the system is demanding. More or less like an old car battery that cranks fine, then refuses to do so again.

Take a look at the power / battery settings on the bottom left of your screen if you can get it running long enough. What is it set too? Full power / Long life ... ?

Try fiddling with the settings.

A *healthy* battery should run the laptop at full power settings until a very low %. I've got one that powers a 45W i7 without issue, and another that powers a ULV i5 without issue despite being several years old. The one in my Dell would often cut off in 3-5 minutes near the end of its life (it's 7 years old and on the original battery).

The cells in this replacement one he got just aren't holding or are capable of outputting the required amperage to keep the thing running. There are some good aftermarket or refurbished batteries out there, and there are some that aren't worth your money. I think this was one of the latter and should be returned for a refund if possible an exchanged for something of higher build/cell quality.
