Observe ventilation requirements
(refer to Chap. 5.2.1.1
) even for charging of temporarily con-
nected cells.

5 Installation
5.1 Demands on the erection site
Danger!
When renewing old batteries, ensure that all electrical loads are switched off before removing the
old battery (separator, fuses, switches).
This must be carried out by qualified personnel.
If you have questions regarding battery system installation, please contact your local HOPPECKE representative.
You can also contact us at our head office directly.
If choosing an installation location, determining space requirements and performing the installa-
tion, observe the relevant installation drawing if it is available.
The floor must be suitable for battery installation; it must:
– have a suitable load-carrying capacity,
– be sufficiently conductive,
– be at ground level (max. thickness of backing elements under racks and cabinets: 6 mm),
– be as free of vibration as possible (otherwise a special rack is required).
Within the EU, follow VDE 0510 Part 2: 2001-12, in accordance with IEC 62485-2: „Safety requi-
rements for secondary batteries and battery installations - Part 2: Stationary batteries“.

4 Storage
4.1 General
After receiving the batteries, you should unpack, install and charge them as soon as possible. If this is not
possible, store the batteries fully-charged in a dry, clean, cool and frost-free location. Excessively high storage
temperatures may result in accelerated self-discharge and premature aging. Do not expose the batteries to
direct sunlight.
Attention!
Do not stack the pallets with the batteries as this can cause damage which is not covered under
the warranty.
4.2 Storage time
Attention!
If the cells/batteries are to be stored for a long period of time, store them fully-charged in a dry,
frost-free location. Avoid direct sunlight. To prevent damage to the batteries, an equalizing charge
must be performed after a maximum storage period of six months (see
Chap. 6.2.5
). Calculate
this exact time starting on the day of delivery. By the end of the max. storage time charge accep-
tance might be declined during battery recharge. Hence, HOPPECKE recommends a suitable
process of charging, which assures a gentle full charge of the battery (refer to
Chap. 6.2.5
). If
storage temperatures exceed 20 °C, more frequently equalizing charges may be necessary (at
temperatures around 40 °C monthly charges). Refer also to
figure 4–1
to retrieve max. storage
times for different storages temperatures. Failure to observe these conditions may result in
sulfating of the electrode plates and significantly reduced capacity and service life of the battery.
Battery recharge during storage time should be carried out max. twice. The battery should be
operated in continuous float charge mode thereafter.
Battery service life commences with delivery of the battery or batteries from the HOPPECKE plant.
Storage times have to be added completely to the service life.
Attention!
Required process for charging the batteries by achievement of max. storage duration:
Charge with constant power of 1 A or 2 A per 100 Ah C

battery capacity. Interrupt charging when
all cell voltages have rised to min 2.65 V/cell (refer also to
Chap. 6.2
).
4.3 Preparing for a several-month storage period
If the storage time extends over a period of several months, make sure to provide an appropriate charger so
that the charging tasks can be performed promptly as previously described. For temporary storage, arrange the
blocks/cells so that they can be temporarily connected in series for charging. The batteries should remain on
their pallets until final installation.
To avoid having to perform the previously described work, we strongly recommend that you con-
nect the battery or batteries to the regular charging voltage supply within six months. Failure to
observe the recharging intervals will render the warranty null and void.
