Starlight SL series (2V50Ah~3, 000Ah)VRLA batteries are recognized as the most reliable and high-quality battery system in the industry—our SL Series. Batteries are designed with advanced AGM(Absorbent Glass Mat) technology. long service life designed with 20 years, the batteries comply with the most popular international standards, such as lEC60896-21, BS629O-4, and Europe Guide.
Stable Quality& High Reliability
Our battery is well-known for its stable and reliable performance. our batteries are easy to maintain; thus, permitting a safe and proper operation of the equipment that the battery powers. The battery can withstand overcharge, over-discharge, vibration, and shock. It is also capable of extended storage.
Sealed Construction
Our unique construction and sealing technique guarantees that no electrolyte leakage can occur from the terminals or any of our batteries. This feature ensures the safe and efficient operation of our batteries in any position. Our batteries are classified as "Non-Spillable" and will meet all requirements of the International Air Transport Association.
Long Service Life, Float or Cyclic
Our VRLA battery has a long life in float or cyclic service. Designed Life: 20 years.
Maintenance-free Operation
During the expected float service life of our batteries. there is no need to check the specific gravity of the electrolyte or add water. There is no provision for these maintenance functions.
Low-Pressure Venting System
Our batteries are equipped with a safe low-pressure venting system, which operates from 1 psi to 6 psi. The venting system is designed to release excess gas in the event that the gas pressure rises to a level above the normal rate. Afterwards. the venting system automatically re-seals itself when the gas pressure level returns to its normal rate. This feature prevents excessive build-up of gas in the batteries. This low-pressure venting system, coupled with the extraordinary high recombination efficiency, makes our batteries the safest sealed lead-acid batteries available.
Heavy Duty Grids
The heavy-duty lead calcium-alloy grids in our batteries provide an extra margin of performance service life in both float and cyclic applications, even in conditions of deep discharge.
