At this point, you can select any item from 2) to 13) to modify the appro-
priate value. You will shown the existing value and prompted for the new
values.
We recommend that you change the EEPROM as little as is absolutely nec-
essary since it is a somewhat delicate process that has occasionally produced
problems (i.e. improper EEPROM values are displayed after the update).
Fortunately this seems to be quite rare and was much more likely to occur
with the old “batch” like process especially if incorrect values were supplied.
Maintaining Your UPS
If you have your UPS long enough, you will probably have battery prob-
lems. Below, you will find some suggestions for replacing batteries. One
important note of caution: at least one user purchased one of the non-APC
batteries noted below and found out that they would not fit into his unit.
This required cutting and soldering and other very undesirable things, so
be extremely careful in measuring the batteries including every millimeter
of the terminal connections which can cause problems.
Although you can do a hot swap of your batteries while the computer is
running, it may not be very satisfactory because the unit will not know that
the batteries have been swapped and apcupsd will continue to show Low
Battery. To correct this situation, you must do a discharge and recharge
of the battery followed by a battery recalibration using apctest. At that
point the battery should be calibrated better. As noted below, Carl has
