At what internal resistance is a battery considered 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. I am using 10 year old ''worn out'' rc model heli Lipos in

I have a dc turnigy smart charger which has a program to measure internal resistance of batteries.I have many 18650 laptop cells that shows measurements from 130 to 230 (if i remember correct).This means that the batteries are unusable?I think it is to high.You say on the article that reaistance is getting higher by usage but how can be so high usually most brands

Guide: Battery internal resistance – what, why and how?

Batteries that have high internal resistance will take more time to fully charge. Also batteries with the lower internal resistance usually can be charged up with the higher current setting (2C – 5C rates).

Why is it Important to Measure Battery''s Internal Resistance?

When the battery''s internal resistance, R DC, is 1 Ω, and the load, R, is 9 Ω, the battery outputs a voltage of 9 V. However, if the internal resistance increases to 2 Ω, the output voltage drops to approximately 8.2 V. In summary, internal resistance influences a battery''s current-carrying capacity. The higher the internal resistance, the

How to calculate the internal resistance of a battery cell

Internal resistance can be thought of as a measure of the "quality" of a battery cell. A low internal resistance indicates that the battery cell is able to deliver a large current with minimal voltage drop, while a high internal resistance indicates that the battery cell is less able to deliver a large current and experiences a larger

Battery Internal Resistance

Batteries with large internal resistance show poor performance in supplying high current pulses. This is because current is decreased with higher resistance. Current equals voltage divided by resistance (i=v/r). So the higher the internal resistance, the lower the current output ability.
