Hiya Danielle, do you know if the battery is a sealed unit or were you given a cartridge of a liquid which looks like water called electrolyte (battery acid) to put into it? The reason i ask is, if you charge the battery with no electrolyte then you will fry it. If the top of the battery doesn't look as if there's anywhere to put water into then it's probably maintenance free.
If you've no charger then install the battery into the bike, only use the kickstart to start the ped as you don't want anything drawing power away from the uncharged battery.
Bring the ped for a good spin ideally avoiding using your headlights, going in & out of work for a couple of days should do it. the battery will be charged & you can then begin using the starter button as normal.
