Drawing a surprisingly fruitless google search.

I have an ultrasound scanner at work, it's portable but the battery pack is totally shot, to the point it can only be used plugged in and if you want to move it from one room to another, you have to shut it down and restart it again.

To all intents and purposes it's a glorified laptop with some very specialised inputs. The things are very expensive but I doubt the battery pack will be anything particularly special. May even be straight nickel hydride AAs in there.

Thing is, due to the £££££ aspect, I'm not poking abut in there. Can anyone recommend a company who can re-cell/refurbish a battery pack?

Just an additional option - you thought of hooking it up to a small UPS to keep it running when you move it around?

I've used this company to replace the cells in a shot fluke network tester.
https://toolbatteriesrepair.co.uk/

The tester was no longer supported by Fluke and a replacement pack was £300 when they did support it.

The refurb cost was £60 or thereabouts.

Why not ask the maker (or post the machine's name and model so that the serried mass of BCFers can look it up and get into competition)?

Any battery pack that's removable should somewhere have a mark for Ni-Cad/Ni-MH/Li-Ion/Li-Poly/etc. for the purposes of recycling/disposal.

If it's lithium ion it's most likely a collection of 18650 batteries which are dead easy to get hold of. The tricky part is taking the casing to bits in such a way as to make reassembly possible and then the replacement cells would need spot welding in.

I've had about 50/50 success personally on repairing laptop batteries and it's always the dismantling part that cocks it all up.

I'm going to have a closer look tomorrow to see what tyoe it is. I do know a replacement battery was unobtainable from the maufacturer because others of my colleagues have tried before now.

The UPS idea is a neat one. Thinking outside the box. While the scanner is portable, it's kept on a trolley so a UPS would be no problem to attach.

Take pics, get any part numbers, find its rating re Volts and Amps and show us.
Knowing how it was assembled and what's inside will give clues
on how best to renovate it.

It may well be an array of 18650s but for all we know it may be Nimh or NiCads
so best to rebuild like for like due the charging characteristics otherwise
you'd have to mod the circuitry to suit as well.

If the original battery is NLA and repair is horribly expensive I'd be musing
over whether patching in an off the shelf rechargeable power pack would be
a viable option.

Unless the battery is really obscure, it will be available elsewhere.

There definitely is a local lad who will take your device/battery pack apart and replace the battery cells. Those cells are widely available. Ali-china-express has tons of those for next to nothing.

Looks like this place has the ability to rebuild
a battery pack.

https://www.countybattery.co.uk/battery-pack-rebuilding/battery-pack-repair-rebuilding/

The pic shows them spot welding tags on batteries which is the trickiest bit
if you haven't got the kit.
They probably do power tool packs mostly but not exclusively.

Just seen the prices......
they go from around £50 to bend over
No idea what you have but larger pack repair can get pretty eye watering

Mind you I'd be inclined to buy one of these and have a go at it
myself.

Edit:
Been doing some research and fancy getting one for myself
but would do this mod before using it

moar edits:
just ordered this one for £19.99 inc P&P
I reckon it will be handy and have a couple of iffy power packs
I can experimend on

Depends on what you want to weld but those ghetto spot welders are probably only good for very thin nickel. This is what they use in the factories...

https://www.ebay.co.uk/itm/SUNKCO-1-5KW-737G-Spot-Welder-Battery-Spot-Welding-LED-Light-for-18650-Battery/123750214835

But to be fair it depends on your needs. Welding up 10S3P or bigger ebike batteries you really want to chew through the work.

There is no danger I'm doing it myself. I used five pound signs for a reason (It didn't cost that because we got it second hand but it would cost that to replace).
