Peukert Exponent. Peukert constant of several lithiumion batteries having different cell The higher the Peukert exponent the faster the effective capacity 'shrinks' with increasing discharge rate In terms of estimation, Peukert's law gets much closer to estimating real world performance of a battery than simple extrapolations of the amp hour rating
What Is Peukert's Law and What Is Its Effect on Batteries? Battle from battlebornbatteries.com
Lead-acid batteries typically have a Peukert Exponent between 1.2 and 1.5 The formula to determine the Peukert exponent is a little more complex-it looks like this: k = (logt2 - logt1) / (logI1 - logI2) If you get the correct answer to this equation, remember.

Lead-acid batteries typically have a Peukert Exponent between 1.2 and 1.5 As a guide: Flooded lead acid batteries - between 1.2 and 1.6; The Peukert formula for a battery's capacity at a given discharge current is: Cp = I n t, where Cp is the capacity available with any given discharge current; I = the discharge current; n = the Peukert exponent, which is a result of Time (T2 minus T1) divided by Current (I1 minus I2), which can be determined by carrying out two discharge tests.
8. Batteriekapazität und PeukertExponent. The Peukert exponent depends on the type of battery: AGM batteries range between 1.05 and 1.15; Gel batteries range between 1.1 and 1.25; Flooded batteries range between 1.2 and 1.6 An ideal (theoretical) battery has a Peukert exponent of 1.00 and has a fixed capacity regardless of the size of the discharge current
What Is Peukert's Law and What Is Its Effect on Batteries? Battle. The formula that states the Law in a usable format is as follows: H is the rated discharge time, in (hours) The Peukert Exponent - this is different for every manufacturer, but should be made readily available by the manufacturer and is often included in their technical specification sheets on their websites
