Connecting batteries in series or parallel allows them to better meet the needs of particular situations. It can also increase their performance to a level single cells may never be able to achieve. Joining them in series increases their output. While doing so in parallel increases the available charge. However, we should avoid mixing old and new batteries.
Overview of Series and Parallel Connections
If we use a single battery on its own, then we limit its ability to what it can deliver. Single battery applications like that include electric clocks and mobile phones. But there are times when we need more than just that. And that’s when connecting batteries in series or parallel adds the extra boost we need.
Wiring Batteries in Series
Wiring batteries in series is the commonest application. Imagine they are like railway freight cars joining up to create a freight train. Each of these adds to the total capacity. Doing so with batteries increments their total voltage, provided we connect negative and positive terminals.
So, if for example we connect four new 1.5 volt batteries in series they will deliver a nominal total six volts. However, if we were to mix old and new ones, then the older, weaker ones would rob some of the newer ones of their charge. Moreover, the entire system would stop working when the first battery went flat.
Wiring Batteries in Parallel
When we wire batteries in series, we connect opposite terminals to achieve the flow. However, a parallel network joins matching terminals instead. As a result the voltage does not increment. But the amount of charge does, meaning the network will deliver the energy for longer periods. In a nut shell:
Connecting Batteries in Series and Parallel
- Connecting four 1.5 volt batteries in series delivers 6 volts for the life a single battery would provide.
- While joining four 1.5 volt batteries in parallel delivers 1.5 volts for the total life of the four batteries.
