My old laptop battery was under warranty and i got a new one because it deteriated so much...

im try to charge/'form' this new battery but the laptop is kicking up a fuss,
its not the laptop because it used to charge the old one. It recognises the battery is there, and that it has 0% (occasionally goes to 1 or 2%) but the charging symbol never shows up. Windows just says it is working of AC power.
The charging light on the laptop lights up as if it was charging, but windows sees an empty battery and is doing nothing.

What should i do?

Thanks
