A Fully Charged Battery Will Always Hold Its Voltage Under Load: This misconception ignores the effects of the internal resistance of the battery and the load it experiences. Under certain conditions, a fully charged battery may show voltage drops when under load due to this internal resistance. The National Renewable Energy Laboratory notes that monitoring voltage under load is key to understanding a battery’s performance.
-
Voltage Ratings Are Constant Regardless of Battery Age or Condition: Battery performance can diminish over time due to factors such as age, charge cycles, and environmental conditions. A battery may show a satisfactory voltage when tested but can fail under actual load conditions because of diminished capacity or increased internal resistance. Research from the Institute of Electrical and Electronics Engineers indicates that regular testing and monitoring can provide insight into a battery’s health.
Understanding these common misconceptions can greatly enhance the effective use of 9-pound batteries in various applications.
