Laptop Li-ion battery repair isn't really an option because reseting the
contoller inside the battery just isn't possible. Given the price of a
new battery is prohibitive and, if it's an older laptop that one doesn't
want to replace, availability of batteries, especially given their 3-5 year
shelf life, is also a problem even if one were prepared to pay the asking
price.

Other than running with a dead battery or removing the battery, are there
any other options for restoring some sort of operation remote from the
mains?

Many thanks.

External gel lead/acid battery, with a small invertor maybe ?

In most countries there are local businesses that specialize in laptop
battery replacement.

Most laptop battery controller chips can be reset. Some companies publish
the method, some do not (STFW).

The problem with Lithium Ion batteries is that they have a limted number
of recharges. It's around 300. Once you go over that limit, they become
useless very quickly. It seems odd because you have a full charge one day
and the next a full charge lasts about 10 minutes and shortly thereafter
a full charge won't even turn the unit on. :-(

Apple had this problem with early iPods. I have several Motorola phones
with dead batteries soldered in. I also have several Macintosh laptops
which are perfectly useable (and run the current version of MacOS)
that have dead batteries and a replacement battery would cost more
than a newer used laptop with a good battery.

Someday, I'll open them up find the correct cells and rebuild them.
Apple even provided a program to reset the controller chip. :-)
