OPzV Battery 2V 490Ah

RPower OPzV range of valve regulated lead-acid stationary batteries
combine the benefits of recombination technology (i. e. virtually no
maintenance due to very low gas emissions) plus the advantages of
conventional vented batteries with positive tubular plates (i. e. long
life and excellent cycling capability).

RPower OPzV valve regulated lead-acid batteries are the ideal
energy source for many different standby applications.

CHARACTERISTICS

POSITIVE ELECTRODE
• Tubular plate with special grid construction, pressure cast from
   antimony free alloy, with highly porous gauntlets that retain the
   active material

NEGATIVE ELECTRODE
• Pasted plates with service life consistent with the positive plates

ELECTROLYTE
• Sulphuric acid bound to GEL

SEPARATOR
• Extremely high porosity and low internal resistance

CONTAINERS AND LIDS
• Made of plastic (ABS). Optionally available in flame retardant ABS
  (according to IEC 707 FV0)

TERMINALS
• Female thread for a perfect contact and low resistance with flexible
  cable connectors

POLE SEALING
• Prevents electrolyte leakage and terminal corrosion

CONNECTORS
• Flexible, fully insulated cable connectors screwed (with 20 ±1 Nm)
  to the terminal with an insulated screw having a hole probe on the
  top for electrical measurement

ONE WAY RELIEF VALVE
• Opens at low pressure and is fitted with a sustained backfire protection
