Yeah; I'm hoping that is the case; also the battery tester showed only 9.8-10V on what's a 12V battery. The only thing that casts doubt is that it wouldn't start with a battery charger on 'start' mode.
Thanks for your contribution - see if I can borrow a neighbour's battery perhaps

You may* be able to rescue it with baking soda if there is corrosion on the terminals.
Disconnect the battery completely.
Sprinkle baking soda on the terminals and connections.
Put a small spritz of water on the baking soda.
Once it has stopped fizzing give the terminals and connections a bit of a scrub.
Grease with petroleum jelly or specialist battery terminal grease.
Let everything dry completely and then reconnect.
*This has worked for me in the past I cannot tell if it will help you but you try it at you own risk. Also eye protection is advisable battery acid in your eye ain't nice.

Lots of newish cars won't even try to start if the battery voltage is much below 12v, as the current draw and voltage drop could cause damage.
If your battery is that flat, a booster pack will struggle if all its power is trying to charge a very dead battery.
Disconnect your battery - ve and cover the battery terminal so it can't touch again. Use a set of jump leads from another good battery/car, or booster.
Key from off to run NOT START. Do the dashboard lights look normal. Glow plug light goes out if it's a diesel.If it looks good and your jump leads are heavy duty, or your booster is rated for cracking an engine as opposed to assisting, you could try starting it.
Alternatively, charge your battery before reconnecting the -ve and trying to start the car.If disconnecting the battery for an hour didn't work. I doubt that overnight would be any different unless the battery is on charge overnight and holds about 12.8v after you switch off the charger.

Ok so if the reset hasn't worked it is most likely that your battery is no good any more and therefore cannot hold a charge.
If you have AA, or similar, membership they can send a van to analyse the battery, give you a report. They will also probably have a suitable replacement on board that they can sell you and fit at your house or where your car is.
Alternatively if you can get a lift to Halfords or a garage they will be able to sell you a replacement (this will be cheaper than the aa)
