_Increased Current Capacity: Parallel connection allows the batteries to deliver a higher total current. Since the batteries are connected in parallel, their internal resistances are effectively reduced, allowing for a lower resistance path for the current to flow. This means that the circuit can draw more current from the combined batteries compared to a single battery.
_Increased Amp-Hours Capacity: The amp-hours (Ah) capacity of a battery represents the amount of current it can deliver over a specific period of time. By connecting batteries in parallel, you increase the total amp-hours capacity of the circuit. This means that the batteries will be able to provide power to the circuit for a longer duration before needing a recharge.
_Unchanged Voltage: Connecting batteries in parallel does not affect the voltage of the circuit. The voltage remains the same as the voltage of each individual battery. In this case, since each battery is 12 volts, the total circuit voltage will still be 12 volts.
_Parallel Configuration: When connecting batteries in parallel, the positive terminals are connected together, and the negative terminals are connected together. This creates a parallel configuration where the current can flow through multiple paths, increasing the overall capacity and lowering the internal resistance of the circuit.
It's important to note that while parallel connection offers increased current capacity and amp-hours capacity, it does not increase the voltage of the circuit. If a higher voltage is required, batteries should be connected in series instead.
