View more6 FAQs about [Battery resistance is below the lower limit]
What is a low internal resistance battery?
One of the urgent requirements of a battery for digital applications is low internal resistance. Measured in milliohms, the internal resistance is the gatekeeper that, to a large extent, determines the runtime. The lower the resistance, the less restriction the battery encounters in delivering the needed power spikes.
What happens if a battery has a high resistance?
As resistance rises, the battery’s voltage drops more quickly under load, often leading to premature voltage cutoff during discharge. Batteries with high internal resistance provide less usable power before reaching their discharge limits, thus shortening their effective runtime.
How does internal resistance affect battery voltage?
The greater the internal resistance, the more significant the voltage drop. To illustrate this, consider a simple experiment with a AA cell. When connected to a 4 Ω resistor, the voltage across the battery terminals might drop from its VOC of 1.5V to around 1.45V. This drop is due to the battery’s internal resistance.
What is battery internal resistance?
Battery internal resistance is the opposition to the flow of current within the battery. For many years, batteries were often assumed to be ideal voltage sources. In simple terms, this means that the battery would always provide a constant voltage regardless of the load connected to it.
Does high internal resistance mean a battery is dead?
High internal resistance doesn't mean the battery is 'dead', just that it cannot maintain the voltage at high current that it could when new. The highest acceptable internal resistance is entirely dependent on the application. Rather than throw old batteries away I reuse them in devices that draw less current.
Why is cell capacity of a battery limited?
Cell capacity is of limited use if a battery pack cannot deliver the stored energy effectively; a battery also needs low internal resistance. Measured in milliohms (mΩ), resistance is extremely important the higher the C rate of the battery; the lower the resistance, the less restriction the pack encounters.
