Measure the battery voltage several times while the
turbine is turned on.
Measure the battery voltage while the turbine is
turned on, shortly before the discharge end voltage is
triggered.

With 12 volt battery blocks, the complete battery set
must be replaced in case of damage.
If the 6 volt battery blocks have reached the above
mentioned use time or the number of loading cycles,
replacing the battery block with a new one is no long-
er worth it. We recommend replacing the entire bat-
tery set.
If the use duration or the number of load cycles is be-
low the above values, it makes sense to replace a de-
fective battery block. However, the following
measures must be taken to adapt/balance the load of
the different battery blocks.
Remove the defective battery block.
Charge the remaining battery blocks and the new
battery block individually. You can use a laborato-
ry device for that. The load voltage must be set to
exactly 7.14 volts. The load current must not ex-
ceed 14 A / 100 Ah.
The load current must have decreased to under 4
A / 100 Ah at the end of the battery block.
