Sealed Lead Acid (SLA) – Absorbent Glass Mat (AGM) vs Gel

Although all lead acid batteries need maintenance, sealed units need far less. A flooded lead acid battery that has been sealed, AGM and Gel are all often referred to as ''maintenance free''. Valve-regulated lead-acid. Sealed lead acid batteries are not truly sealed. If the battery were to overheat, say due to excessive charging, gases could ...

Thermal runaway in valve-regulated lead-acid cells and the …

A series of 6 V, 100 A h, valve-regulated lead-acid (VRLA) batteries were overcharged at potentials of up to 2.65 V per cell and the currents, temperatures and gas-evolution rates measured during thermal runaway. From these results, it was concluded that separator dry-out was the critical parameter that controls thermal runaway behaviour.
