Danger!

– The AquaGen® recombination system has to be cleaned like the batterie cell/block by using a moist cotton- or paper towel.

Note: While charging – especially boost charge – the AquaGen recombinationsystem will heat up. Therefore do not clean the AquaGen recombination systems during boost charge

– Plastic parts of the batteries, especially the cell container, have to be cleaned with water or water moistened cleaning cloth without additives.

– After cleaning the battery surface has to be dried with appropriate measures, like moist antistatic cleaning cloth (e.g. cotton).

Note: In OSP.HC and OSP.XC battery cells deposits (streak formations) might buildup on the inner surface of the cell jar. This occurs mainly in the area of the electrolyte level surface. These deposits are caused by additves in the separators which are used as antioxidant to protect the plastic material of the separator. Light washouts of this additives over battery service life cannot be avoided. This fact has neither negative impact on the electric performance of the battery nor on battery service life.

9 Testing the battery system

9.1 Performing the capacity test (short form)

Perform tests in accordance with EN 60896-11 “Stationary leadacid batteries - Part 11: Vented types; General requirements and methods of tests.” In addition, note special test instructions, e.g. in accordance with DIN VDE 0100-710 and DIN VDE 0100-718.

The following is the short form of the procedure for testing the actual capacity of your battery system. Also observe all instructions in Chap. 9.2.

We recommend performing an equalizing charge on the battery system (as described in Chap.

6.2.5) before performing this test.

Perform the equalizing charge no more than 7 days in advance and no less than 3 days in advance.

1. Make sure that all connections are clean, secure and noncorroded.

2. During normal battery operation, measure and record the following parameters:

– Electrolyte density.

– Voltage of each cell (or monobloc battery).

– Temperature of at least one out of every ten cells (monobloc batteries).

– Voltage of the complete battery system.

3. Interrupt the connection between the battery system that you wish to test and the charger and all consumers.

4. Prepare an adjustable load that you can connect to the battery system. The load current must correspond to the maximum permitted current for which the battery is designed.

5. Prepare a shunt that you can connect in series with the load.

6. Prepare the voltmeter so that you can test the total voltage of the battery.

7. Connect the load, the shunt and the voltmeter. Simultaneously start a time measurement.

8. Keep the load current constant and measure the voltage of the battery system in regular time intervals.

9. Check the row connectors (block connectors), step connectors and tier connectors for excessive heating.

10. Calculate the capacity of the battery system using the following formula:

Capacity [% at 20°C] = T

T a

T s a

/T s

) x 100

= actual discharge time until the permitted minimum voltage is reached.

= theoretical discharge time until the permitted minimum voltage is reached.

11. Reconnect the battery system as originally connected and perform a boost charge (see Chap. 5.13)
