Austin Carr asked the right question with what's the battery voltage. 2 volts on a 6 volt battery probably means the battery is stuffed. In a lead acid battery each cell is just over 2.3 volts per cell when fully charged. What they called fully discharged is about 1.95 volts per cell. So for a 6 volt battery with three cells about 5.85 volts. I would think anything lower means the battery is broken. I've found that with SLA batteries, once you start measuring low voltages on them nothing you do brings them back.
A truly intelligent charger (one measuring the voltage to start with) is probably not even starting to try to charge it.
The battery also acts as a ballast/load to keep the dynamo voltage down. If you run a car without a battery in circuit (or a dead one) then the voltage will shoot up and exploding bulbs may well be the result as noted above!
