SMF VRLA

Industrial Revolution Business

A valve-regulated lead-acid battery (VRLA battery) sometimes called sealed lead-acid (SLA), gel cell, or maintenance free battery[1]. Due to their construction, the gel and absorbent glass mat (AGM) types of VRLA can be mounted in any orientation, and do not require constant maintenance.

The term "maintenance free" is a misnomer as VRLA batteries still require cleaning and regular functional testing. They are widely used in large portable electrical devices, off-grid power systems and similar roles, where large amounts of storage are needed at a lower cost than other low-maintenance technologies like lithium-ion.
