 Battery Connections and Voltage Output: The Difference Between Series and Parallel Connections

Series and Parallel Connections for Batteries

Can you tell me is there an simple way to get 12 volts from 5 volt AA batteries.  I know its not exactly a DIY question but if you could help it would be really appreciated.

Thanks for your electrical question Tristan.

Battery Connections and Voltage Output

The Difference Between Series and Parallel Connections

• A Series connection or when you place the 5v batteries end to end you increase the voltage by the number of batteries.
• For example, if there are 2 5v batteries placed end to end then you would have 10v, 3 batteries would give you 15v.
• A Parallel connection is where the batteries are connected side by side, or straight across the terminals, will produce the same voltage but multiply the lifespan of the battery power, where is each battery was 2500mAh it would then be 5000mAh when there is a parallel connection of two batteries.

Example Table of Battery Connections
Each Battery – 1.5v 2500mAh
2 in Series = 3v at 2500mAh (end to end)
2 in Parallel = 1.5v at 5000mAh (side by side)
