If it is really cold where you live you will need a battery with higher cold cranking amps (cca). Take that one back and buy a good name brand battery like an interstate battery with at least 700 cca.

Check all battery connection they must be clean and tight. Also check negative battery connection on frame and motor. If that don't help have alternator tested. It should be putting out 14.5 volts to keep battery charged. If it's not replace it. If all that checks out you might have a parasitic draw issue.
