Is battery and voltage same?
The electric potential difference or voltage of a battery is the potential energy difference across its terminals for every Coulomb of charge. The positive terminal of a battery is higher in electric potential than the negative terminal by an amount which is equal to the battery voltage.
Does connecting batteries increase voltage?
Connecting a battery in series is when you connect two or more batteries together to increase the battery systems overall voltage, connecting batteries in series does not increase the capacity only the voltage. We recommend you charge each battery individually to avoid battery imbalance.
What voltage are batteries?
Common batteries, their chemistry, and their nominal voltage
| Battery Shape | Chemistry | Nominal Voltage |
|---|---|---|
| AA, AAA, C, and D | Alkaline or Zinc-carbon | 1.5V |
| 9V | Alkaline or Zinc-carbon | 9V |
| Coin Cell | Lithium | 3V |
| Silver Flat Pack | Lithium Polymer (LiPo) | 3.7V |
Why do series batteries increase voltage?
When you add two batteries in series the potentials (voltage) are added because since the same charge is moved twice each time thru the same voltage (potential) the total work done is 2 * V but the current flow remains the same.
What happens when you connect batteries of different voltages?
As covered in the section Connecting batteries of different voltages in series above, the greater the differences in either voltage or amp hour rating, the more the discharging and recharging is unbalanced and the more damage you do to the batteries through over-discharging and over-charging the weaker ones and under-charging the stronger ones.
What are the different types of battery connections?
Battery Connection type: Series (Increases Voltage) Connecting batteries in series means to connect the positive terminal of the first battery to the negative terminal of the second battery and so on down the string. The interconnecting cables must have equal lengths and resistance to equalize of the load.
What does it mean to connect batteries in series?

What does it mean to connect batteries in parallel?
For more information on wiring in parallel see Connecting batteries in parallel or our article on building battery banks. The basic concept when connecting in series is that you add the voltages of the batteries together, but the amp hour capacity remains the same.
