Battery Replacement Considerations
Note: It is critical that new batteries be installed with the utmost care,
failure to do so will result in instrument failure.
For Releases that use the replaceable alkaline or Lithium battery options, the user should exercise care in
selecting replacement batteries. Check both the polarity and open circuit voltage of each cell. EdgeTech
recommends: for Lithium Units Tadiran type TL-5920/S batteries. For Alkaline Units Energizer EN93 Type
batteries.
Note: It is not possible to estimate the remaining capacity by measuring
its open circuit voltage.
