So when you attach the batteries in parallel, neg to neg and pos to pos you are not completing the circuit, but somehow the voltages equalize between the two meaning that current has to flow.
What happens if you put two batteries in parallel?
When two or more batteries are placed in parallel, the voltage in the circuit is the same as each individual battery. That is two, three, four or more 1.5 volt batteries in parallel will produce a voltage of 1.5 Volts! When batteries are connected in series, the voltage increases.
How do you equalize two batteries?
Battery EqualizationThe batteries must be fully charged to begin with.Disconnect all loads. Remove any hydrocaps fitted to the cells.Connect the charger and set it to the equalizing voltage. ( Batteries will begin gassing and bubbling vigorously.More items
How often should I equalize my batteries?
Many experts recommend that batteries be equalized periodically, ranging anywhere from once a month to once or twice per year. However, Trojan only recommends equalizing when low or wide ranging specific gravity (>0.030) are detected after fully charging a battery.
Do batteries in series equalize?
No, a single series string will not equalise the cells in the normal course of charge/discharge, although the degree to which this is a problem and the degree to which it can be dealt with varies by battery chemistry - from not at all, to a reasonable amount.
Can you run different batteries in parallel?
Its generally not a good idea to put batteries in parallel because one can be more charged and have a higher voltage and this will cause it to drain quickly as it feeds the other battery. No two batteries are identical, even if taken from the same pack or same production run.
Do voltages in parallel add?
Ideal voltage sources can be connected together in both parallel or series the same as for any circuit element. Series voltages add together while parallel voltages have the same value.
How many 12V batteries can I connect in parallel?
two batteries You will get 12 volts and 1200 CCA if you have two batteries in parallel. If you have 2x the current reserve you can operate your electronics for 2x as long as you dont have to charge the batteries.
Can you overcharge a deep cycle battery?
Both overcharging and undercharging will have serious adverse effects on the lifespan of a deep cycle battery. In particular, you can seriously shorten the lifespan of a battery if it is used in a deep cycle application that it was not designed for.

Whats the difference between hooking up batteries in series and parallel?
The main difference in wiring batteries in series vs. parallel is the impact on the output voltage and the capacity of the battery system. Batteries wired in series will have their voltages added together. Batteries wired in parallel will have their capacities (measured in amp-hours) added together.
