Measures during Storage
Appropriate storage, based on the FIFO ("first-in, first out")
method avoids excess storage time.
If the blocks need cleaning, do not use a cleaning agent
and instead use cotton cloths soaked in water without any
additives.
For longer periods of storage it is recommended that open-
circuit voltage be inspected at the following intervals
• Storage at 20°C: after 6 months, then every 3 months.
• Storage at 30°C: after 4 months, then every 2 months.
Recharging is necessary if open-circuit voltage is < 2.11 V/Z
Continuous charging *) is considered a possibility if the
measured open-circuit voltage is < 2.11 volts per cell.
*) Continuous charging means maintenance charging at low
rates, approximately equal to self-discharge and sufficient
to keep the battery fully charged. It can be carried out either
by IU charging (normal trickle charge mode) or I charging
(constant current) with limited current.
Continuous charging during storage
Depending on the charger, the charging time must be ex-
tended by 24 stands for each 0.04 V below the maximum
voltage. The minimum voltage is the lowest limit.
At temperatures < 15 °C a charging time of 20 stands is
recommended.

SAFETY NOTICE WARNING!
RISK OF INJURY!
Improper installation and installation can lead to serious per-
sonal injury and/or damage to property. This work may there-
fore only be carried out by authorized, instructed personnel
familiar with the operation of the device and in compliance
with all safety regulations.
• Ensure sufficient freedom of movement.
• Ensure order and cleanliness at the workplace. Loose or
loose components and tools are sources of accidents!
3.1 Battery rooms, ventilation and general
requirements
General: This is only a guideline and contains excerpts from
national and international standards. See DIN EN 50272-2
for more detailed information. Please also follow the user
instructions and installation guide.

3.2 Temperature

• AGM Batterys are designed to operate in the -15°C and
+55°C temperature ranges..
• The battery room temperature should be between +10 °C
and +30 °C. The battery should be operated in a tempera-
ture range of -15 °C and +55 °C.
• The optimum temperature is the nominal temperature of
20 °C.
• Higher temperatures reduce the design Above 40 °C there
is a risk of the „thermal runaway effect" .
Lower temperatures reduce available capacity and extend
recharge time.
