Honeywell is not responsible for misprints or errors. These Mhos values are benchmark averages created from fresh samples of major brand batteries. If you find consistent, minor variations in readings from multiple
samples of a battery, it is likely due to manufacturing differences. However, if the readings are excessively low, the battery is not as good as the benchmark average. If this chart does not include the battery you are
testing, it may be necessary to generate the values using the procedure listed above.
