Parallel and Series circuits

Parallel and series circuits
 There always exists a question how to double currency and leave voltage the same ?  or how to increase voltage while leaving capacity the same ? If we want to answer these questions we have to be aware of parallel and series circuits...
 When we connect our batteries in series actually we increase the voltage while maintaining capacity (amps an hour or second) the same.
 If we connect our batteries in parallel, I want to say that we don`t increase the voltage, we only increase capacity. That`s the different between series and parallel.
 To prove my words, I`ve done experiment and got data that represent relation between voltage and current while connecting baterries in series and in parallel :
Series
Voltage : 2.45volts
Capacity : 0.7 amps
Parallel
Voltage : 0.8 volts
Capacity : 2 amps
 There is a question what happens when we connect series and parallel circuits together ? what do we get ?
 After connecting parallel and series together I got strange answers. My hypothesis was that they both (volts and amps) would increase but they stayed minimum. So Current was 0.7 amps and Voltage 0.8 volts. So it didn`t make any sense.
