SUNLIGHT Battery SPB12-120 12V 126Ah (C20) VRLA - AGM

The SUNLIGHT SPB series is a VRLA (Valve Regulated Lead Acid) battery that has been developed to provide reliable performance in the Uninterruptible Power Supply (UPS), Telecom, Information Technology (IT) and Emergency Power Supply Systems. The VRLA battery is a rechargeable battery type with a safety valve, which allows the internal pressure to be released in case of overcharge. This battery type is maintenance free as there is no need for topping-up water or electrolyte during the entire service life. The SUNLIGHT SPB range of VRLA batteries features models with capacity from 33Ah up to 200Ah.

Key Features of SPB series

• High performance
  With low internal resistance and efficient discharge characteristics, SPB batteries can be applied to many fields, both in cycle and stand-by use.
• Maintenance free
  During the service life, there is no need to check the level of the electrolyte or to add water. The gases produced during electrolysis are almost completely recombined to water (up to 99%) through an effective reaction between hydrogen and oxygen.
• Safety valve design with AGM separator
  Excessive gas produced by overcharge or an incorrect charging method is released through the safety valve, which detects rising internal pressure and allows gas to exit and then automatically reseals. The AGM (Absorbent Glass Mat) separator maintains a constant distance between the plates and immobilizes the electrolyte, so that the possibility of acid leakage is minimized.
• Leak and spill proof container
  The construction of the SPB batteries with a highly resistant material -standard ABS (UL94 HB) or optionally flame retardant ABS (UL94 V0)- guarantees that no electrolyte leakage will occur from the terminals or case. The sealed construction of the battery allows perfect operation in any position (vertical or horizontal but not completely inverted position).
• Wide temperature range and float service life
  SPB batteries operate within a wide range of temperatures. The nominal service life is 10 to 12 years in float / standby applications while operating in optimum temperature of +20ºC to +25ºC.
• Low self-discharge rate
  Using a lead / calcium grid alloy, the self–discharge is minimum. The battery can be stored for 9 months under normal conditions (+20ºC to +25ºC) with no permanent effect on the capacity or the expected service life.
