Due to the fast pace of industrialisation, demand for more efficient and long lasting SMF VRLA batteries has increased significantly
By Belal Khan
Solar and telecom equipment require standby battery systems, which is one factor driving the demand for SMF VRLA batteries. Sealed maintenance free (SMF) batteries or valve regulated lead acid (VRLA) batteries (the latest batteries feature a combination of both technologies –the VRLA hybrid technology) are also in demand across sectors.
Ideal applications for VRLA batteries
Deep cycle, deep discharge applications
- Solar applications
- Uninterruptible power supply systems (UPS)
- Electric power system (EPS)
- Emergency backup power supply systems
