The above reference document discusses ohmic measurements and the use of this data in determining battery state-of-health (SOH). While a very useful tool, full reliance on ohmic measurements in determining the condition of a battery cell/unit can often be misleading and can give inaccurate “good” and “bad” indications. Also, in many cases, the ohmic value […]

Making Sense of Vendor-to-Vendor Ohmic Variance As companies transition from calendar-based battery maintenance to real time battery monitoring or to a new portable monitor vendor, the challenge is to reconcile the historical data with the new solution, this is particularly true for the cell/unit ohmic data. The measurement of the ohmic value can be made […]
Clarifying Two Key Methods for Evaluating Battery Health The first point is that resistance testing and impedance testing are carried out by similar but importantly different methods; resistance is measured by using a DC current to perturb (excite) the cell, while impedance uses an oscillating (AC) current. The resistance method eliminates other parameters present in […]
A properly implemented maintenance program will aid in prolonging battery life, prevent avoidable battery failures, reduce premature battery replacement, ensure that the battery systems is charged properly at full capacity and deliver it the stored energy to the load when required. Eagle Eye Power Solutions’ maintenance procedures are based on the recommendations issued by the […]
