Testing batteries the conventional way,
by discharge the battery for a 3, 5 or 10 hours period, is not only
difficult to make but also a risk to get an power lost or brake under
the test. When these tests have a long performance time, they are
also very expensive. If there is one bad battery that must be changed,
the test has to be done again afterwards to make sure that the rest
of the batteries are good.
Since the user is aware of the costs, the batteries may not be tested
in time and that can result in a breakdown or that some functions
don’t work, like disconnect high voltage switchboard at 10 KV
or a lost process control.
We have noticed this and now we can make these tests of the batteries
without any influence of the running.
With a well developed instrument that measures the conductance in
the battery, we can settle the batteries remaining capacity.
With our long experience of testing batteries with different methods,
like Batscan or discharge with constant power with Torkel load, we
can show the advantages with the conductance method witch gives a
more detailed result that is easier to read when we hand over the
protocol after the test.
-the test does not influence customers load
-low cost for the test
-easy to read out the protocols
-the ageing of the battery can be followed
-with this test a battery change can wait until it is necessary
UPS-battery with just 5 battery-blocs
changed
These batteries have been measured with another method,
which has shown that 5 batteryblocs are in bad condition. These
5 blocs have been changed.What you didn´t see was that
the rest of the batterieswere in very bad shape too and needed
to be changed. With Servicepoolens measuremethod you can see
every single batterybloc and bad batteries can be changed in
time. |

UPS-battery that was without any remarks
6 months ago
One batterybloc of 99 is in bad condition. At the latest
batterytest 6 months earlier the newinstalled, free ventilated
Hoppece-batteries were without any remark. |
