How much power is in a 100ah battery

In article , says... Also nicad's don't like to be float charged like a lead acid battery. What does "float-charged" mean? "Floating a battery" refers to keeping a constant voltage charge on the battery that is just high enough to replace the natural losses in the battery. This is typically done with lead acid batteries that are to be maintained at peak charge but not used for long periods. A fully charged 12 volt lead acid battery has a voltage of around 12.7 volts. It will slowly discharge itself with no load on it if left alone. If a constant 13.3 to 13.6 volts (depending on temperature) charge is left on the battery it will replace the self discharge energy of the battery. This voltage can be left on the battery indefinitely and will not harm the battery. Any higher charge voltage, only by a few tenths of a volt, for long periods will harm the battery. When initially charging the battery the voltage needs to be at around 14.2 volts for finishing the charge. Some gassing of the battery needs to take place in the final phase of charging, slight overcharging, in order to properly top off the cells. Then switch to the float voltage 13.3 volts to maintain.
