Apologies battery did / is not . Its at 0 %  i have taped this one around m but goes off all the time!

Chargers do not hold a charge. It just charges the battery. What you need is a new battery. All batteries wear out and die. See- Dell Laptop Battery - Frequently Asked Questions | Dell US

There is no new genuine Dell battery for your old model. Always use the charger plugged into an outlet. The laptop will be a desktop replacement until you can buy a new computer. Beware of all the scams from online sellers.

If you've had the issue with multiple AC adapters, it's the DC jack you need to replace, not the adapter.
