9 volt batteries like this are typically alkaline. Internally, they have six 1.5V cells connected in series. There is a so called 9V lithium ion battery, in the same package, that has a couple of internal 3.6V cells (4.2V fully charged) for 8.4V when fully charged.

Series alkaline batteries

Always make sure that series batteries have about the same voltage/charge and capacity (Ah/mAh), for even and safer discharge and recharge if rechargeable.
