User Instructions

charged immediately after each discharge. The battery should be charged using the constant voltage method (ripple
voltage should not exceed 1% of the nominal voltage) with the limitation of the charging current, using devices (power
supplies, chargers etc.) which can be used with this type of batteries. The recommended charging current should be in
the range of 0.1*C ÷ 0.2*C (C-nominal capacity of the battery), the maximum charging current is 0.3 *C. To ensure the
longest lifespan, it is recommended to use power supplies with temperature compensation of the charging voltage.
 Buffer operation:
The charging voltage for a single battery during buffer operation should be in the range 13.60V ÷ 13.80V
at 25 °C. The voltage temperature compensation for buffer operation should be -18mV /°C.
 Cyclic operation:
The charging voltage for a single battery during cyclic operation should be in the range 14.40V ÷ 14.90V
at 25 °C. The voltage temperature compensation for cyclic operation should be -30mV/°C.
 Maintenance:
Batteries made in VRLA technology are maintenance-free batteries, it means that they do not require monitoring the
electrolyte and the periodic addition of distilled water. Maintenance is limited to ensuring the battery operation in optimum
conditions depending on the operating mode and adequate cleanliness of the battery housing, which, if necessary, should
be cleaned with a cotton cloth humidified with water without detergents. Coat battery terminals with e.g. Vaseline to
prevent corrosion if needed. The battery capacity should be checked at least once per year; to do that, leave a fully
charged battery for 24 hours and then discharge with I
20
= the nominal capacity/20 up to the discharge voltage of 10.5V. If
the measured capacity is less than 80% of the nominal capacity, the battery should be replaced.
 Environmental protection and recycling:
 Due to the content of harmful substances, used batteries are hazardous waste (EWC 160601). According to the
Directive 2006/66/EU and Polish regulations, waste electrical and electronic equipment should be disposed of
separately from normal household waste (return old batteries to the manufacturer or recycling facility).
 Cautions:
(a) Contains sulfuric acid, (b) Danger! High voltage, (c) Be careful, (d) No smoking, sparks, (e) Wear your safety
glasses, (f) Follow instructions, (g) explosion risk, (h) recyclable, (i) separate collection.
