6.3: Resistors in Series and Parallel
A battery with a terminal voltage of 9 V is connected to a circuit consisting of four (20, Omega) and one (10, Omega) resistors all in series (Figure (PageIndex{3})). Assume the battery has negligible internal resistance. Calculate the equivalent resistance of the circuit. Calculate the current through each resistor.
At what internal resistance is a battery considered dead?
At what internal resistance is a battery considered dead?
Internal resistance
The internal resistance of a battery may be calculated from its open circuit voltage VNL, load voltage VFL, and the load resistance RL: This can also be expressed in terms of the Overpotential η and the current I:
9 Different Types of Batteries and Their Applications [PDF]
They typically offer higher capacity and lower internal resistance than alkaline batteries. In addition, they have improved low-temperature performance, improved leakage resistance, and low self-discharge. ... Below are some factors to consider when selecting the right type of battery for your use: #1 Energy Density.
Relation between battery cell capacity & internal resistance
Is more correct to say that internal resistance is related to battery discharge current. Indeed, a battery with higher discharge current will have a smaller internal resistance. For example, a LiPo prismatic cell of 3000mAh used to have a bigger discharge current than a cylindrical LiIon with the same capacity.

A Guide to D Batteries and Rechargeable D Batteries
As we have already noted, like many other sizes, D batteries are also available in environmentally-friendly rechargeable models. Instead of replacing a spent battery, all the user needs to do is remove the rechargeable D battery and insert this into a compatible charger to be recharged and reused.
