If each battery is identical, yes.
YES
A way of connecting batteries together to provide more current is to connect them in parallel. This allows more capacity at the same voltage. If the batteries were connected in series the voltage would be increased.
no..... The battery with lower voltage will consume power from the higher one...
A == B (- 12V +) (- 12V +) (- 12V +) A single 12V battery in series with 4x 12V batteries connected in parallel... Total voltage from A to B is 24 volts! Note that the single battery in series will limit the total current capacity to that of a single battery.
12 volts only refers to the voltage, to be able to say anything about charge time you also need to know the capacity rating in amp hours of the batteries. Assuming lead-acid batteries the charger needs to go to > 14.4 V and then a proportional amount of amps as compared to the capacity rating of the batteries. A rough approximation is that batteries needs to be charged with about 1.4 times their amp rating. An 1 Ah battery would need 2 hours on a 0.7 amp charger for instance.
the voltage across that resistor will increase if it is in series with the other resistors. the current through that resistor will increase if it is in parallel with the other resistors.
If you connect 2 six volt batteries in parallel it will still give you six volts but it will give you twice the cranking power. To obtain twelve volts from the two six volt batteries they will have to be connected in series.

Two batteries, put them in series and either measure the voltage with a voltmeter, or with a fan connected watch the speed increase. A parallel connection will increase the current available but will not have an obvious change in output, as the current available is just that, ready for use. You can do something else with parallel and that is to have a volt meter showing that there is a current flow between the two batteries and that is why batteries connected in parallel will discharge.
It will if the batteries are connected in series. If they are connected in parallel, the lamp will burn longer, but not brighter.
You will have a 12 Volt source with double the charge capacity.
There will be no effect on the voltage. That is the effective voltage will be only 12 volt. But there will be increase of current.
Parallel or Series Connections for BatteriesTo increase current [measured in Amperes], you connect batteries in parallel. To increase voltage, you connect batteries in series.
All batteries connected in series have additive voltages. All same voltage batteries connected in parallel have the same voltage as one of the parallel battery but their amp hour capacity is increased. Example series wound batteries of four 1.5v batteries, would lite a big 6v flashlight. (all 1.5v batteries = Et= 1.5v x4=6volts). That is the big square battery to lite square flashlights.

Two 6 volt batteries connected together in parallel will still maintain 6 volts but their amperage capacity will be doubled.
Yes, series and parallel connection of batteries is possible. When connected in series Voltage increases. In parallel, Current increases but voltage is constant.
Yes, this is known as a parallel connection. When wired in this configuration you will get double the amp/hours out of the batteries over just using one battery. Batteries connected in series results in the voltages being additive. Batteries in parallel results in longer amp/hour capacity.
