Can AGM Batteries Suffer Thermal Runaway like Lithium Ion Batteries?

 

 

The Question –

Can AGM Batteries suffer thermal runaway like Lithium Ion Batteries: Are they safe?

 

The Answer –

Does everyone know that when our RG series batteries are subject to the destructive overcharge test that they do NOT thermally runaway?

They get HOT about 260F, the electrolyte boils, the water turns to steam and the excessive internal pressure opens the vent valves releasing the steam (H20) NO ACID is expelled.  This continues for about 10 minutes and as soon as the battery runs out of water the charge current stops and the battery starts to cool down to ambient.
