For a couple of cheap tools I have that are 18v, when their batteries went knackered I bought some plastic mounts designed to take my Bosch pro batteries, then hollowed out the failed batteries and soldered the Bosch shaped adapter to the terminals
I've also pulled the same trick on a non-pro Bosch tool where the battery is slightly different mounting wise; the Bosch non-pro battery now has a pro receptacle on the bottom and the two batteries work in parallel for a 150% longer run time
Blank Bosch adaptor, about 8 quid

Mounted on a working Bosch battery (more capacity; the all4 charger will charge both batts if they're connected):

Hello, At the moment, all my batteries are working in perfect order, and no issues with them. When we do any DIY stuff at home, even though its only a £30 tool that we use as a screwdriver, it lasts hours, with no problems. Its only when I am having a better day with my pain management I want to carry on doing stuff, but even though its only an hour quick charge system, if I stop and wait for the battery to be charged enough to carry on, my body seizes up and I can't do anything else that day... possible weeks, without having to take the full dosage of Morphine, of which I try and keep it to a minimum and when I need sleep.
I have started to look at getting someone with a 3D printer to print myself an adapter for this drill, that will allow me to use the "all for one" battery system... Like those adverts that say get the tool, battery free, cheaper, and have 1 battery for all the tools... interchangeable batteries for all the tools they provide. I think this is by Ryobi but unsure...
When the weather is on my side, and been dry for a few days (I like to do everything outside if I can), I normally try and get up between 10:30am, and 12:30pm, I then take my pain medication, do a bit if "research" to refresh my memory and plans that I thought of nights before from YouTube, and then plan everything out, and by this time, I start about 2pm, I do as much as I can, but the drill screwdriver ends up loosing power by 6pm, and our main drill will keep going all day (bigger battery - with a spare battery).
However, I have problems physically, and mental health issues, so I can only do stuff when Pain is less than a 7/10, and mental health better than 3/10, then adding the weather to this, I try and keep going as long as I can, and having a spare battery will help me get projects done faster and easier.
I don't want to spend loads of money on tools that wont get used enough, if I am able to do more DIY stuff in the future I will be more than happy to spend more on either upgrading my current tools, or buy a set of new semi-pro tools. But first, I need to get used to the workings of the more dangerous power tools, as I don't want to get a tool that is £200+ and either break it, do things wrong as I will have 0% experience on using the tools, finding tools too dangerous for my liking (like a multi-tool, a rotary tool (aka Dremel))
Also, I don't know if they are any good now days, but I do have about 3 "floors" of a double Garage, full of my Grandfather's tools, who passed away back in 1991... apparently left me all of it, which has nearly everything you could ask for, from Mechanical/automotive/engineering tools - to woodworking tools - work benches - blacksmithing - Gardening tools - and loads more. ( I Just turned 3 when he died, and I saw the tools he left me back around 2006... about 10 years after my nan died. My uncle who isn't a good man, lives in the house, and has all of it. My Granddad was a Royal Marine, and became an Royal Marine Engineer, and had the ability to fix anything the military put towards him, and his tool collection allowed him to do this after he left the military. I have no idea if his tools are any good compared to tools you get these days.
So, yes basically, I have some cheap non pro tools, that will and do allow me to be able to get stuff done, with very little problems after a few "upgrades" its even better. The only problem I have had with the drill that is my fault really, is somehow fusing the chuck plastic together with a screwdriver bit inside, and no real way to open it, without going though the gear box. It now has a metal chuck and there are no more problems here. (I did manage to get the screwdriver bit out, but somehow the chuck wouldn't unscrew, I think I broke it trying to get the screwdriver bit out.
As this is a drill that's cheap, and only used to screw in screws, one day when financial crisis is over, and supply comes back to normal levels I do plan to get a impact driver, based on project farm YouTube channel testing what's better for what tasks, (good channel, that lets you see how good DIY products are, and the torque test channel from YouTube which tests impact wrenches mostly, but how powerful the tools really are over what the manufacturer say, and charts each tool, on price, size, power etc... again a good watch.
