This is a quick, non-comprehensive battery and charging system check. The bike used is a 954rr but the article is applicable to most bikes or automobiles.

With the ignition OFF, remove whatever is needed to gain access to the battery terminals.

Typically on a bike you need to remove the seat.

Measure the DC voltage of the battery. You should see between 12v and 13.8v on a good battery without the engine running. 6x2.1v cells =13.8v

Start the bike and measure the DC voltage again. The voltage should read more than 14 volts with the engine running. If the voltage is lower, raise the idle slightly. If there is still no increase in voltage the charging system needs to be verified.
