80Ah 12V VRLA AGM Sunlight SPb

The SPB range of SUNLIGHT Valve Regulated Lead Acid batteries has been developed as advanced series, to provide reliable performance in the Uninterruptible Power Supply, Telecom, Information Technology and Emergency Power Supply Systems. The battery can be used in PV systems.

The Valve Regulated Lead Acid (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.

High Performance
With low internal resistance and efficient discharge characteristics, SUNLIGHT 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
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; then automatically
reseals.

Separator Technology
The Absorbent Glass Mat (AGM) separator, used in the SUNLIGHT batteries, is a highly porous
material, which achieves maximization of oxygen diffusion and facilitates the reaction of active materials
in the plates.The separator also maintains a constant distance between the positive and the
negative plates and immobilizes the electrolyte, so that the possibility of acid leakage is minimized.

Performance on Wide Temperature Range
SUNLIGHT SPB batteries operate within a wide range of temperature while the optimum
temperature for the operation of the battery is 20ºC - 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 - 25ºC) with no permanent effect on the capacity
or the expected service life.

Leak and Spill Proof Container
The construction of the SUNLIGHT SPB battery guarantees that no electrolyte leakage can occur
from the terminals or case. A highly resistant plastic material is used, available in either standard
ABS (UL94 HB) or flame retardant type (UL94 V-0).

Float Service Life
The nominal service life is 12 years in float / standby applications (20ºC).

Multi-position Usage
The sealed construction of the battery allows perfect operation in any position
(vertical or horizontal but not completely inverted position).
