Sealed Lead Acid (SLA) Battery – these batteries are valve-regulated to release gas in case of excessive internal pressure build-up but are otherwise sealed as opposed to flooded lead acid units which can be opened to top off the liquid electrolyte. SLA products are generally maintenance-free, vibration resistant, leak-proof and able to operate in any orientation.
SLA have lead electrodes with an electrolyte of dilute sulphuric acid that is either impregnated into a mat (Absorbent Glass Mat) or held within a silicon gel (Gel). For more on these two battery types see the article Sealed Lead Acid (SLA) – Absorbent Glass Mat (AGM) vs Gel.
Sealed Lead Acid batteries are part of the lead acid chemistry. See What is a lead acid battery for more details on this battery type.
