The Assessment field on the Review/Analysis page contains generated comments based on inspection observations, voltage thresholds and average temperature. Inspection Alerts are generated comments based on Positive plate growth, Positive plate shedding and Negative plate shedding observations during an inspection. Battery condition generated comments are based on cell voltage thresholds and average battery temperature. Comments are entered by the service […]

The cell condition report chart plots the voltage of each cell during each inspection based on its relationship to the other cells. To interpret the cell condition report chart click the About> link at the top left of the chart. To review the amount that each cell contributes to the battery score click the % of current score> link at

The Battery condition trend chart plots the score of each battery inspection and applies a trendline to the markers. The consistency of the markers indicates the consistency of charging/discharging practices. The trendline slope indicates the aging of the battery. A trendline that trends upwards indicates an improvement in usage and/or charging practices, but eventually, the trendline will always be downward

The Battery temperature chart illustrates the battery temperature during each inspection and applies commonly stated battery life expectancy compensation based on average battery temperature. It generates a life expectancy comment in the Assessment comments at the top of the Analysis section. If the battery is Dedicated to a truck, the Estimated hours/cycles remaining displayed on the Estimated hours/cycles remaining chart

The % charged chart plots the state of charge during each inspection. When considered along with usage and charging practices it can be instrumental in deciding the probability of battery sulfation.

There are numerous factors that affect a battery’s service life that make the Estimated hours/cycles remaining chart less of a definitive calculation of when a battery is spent and more a decision making tool.
