- doggodaddo78 6y agoWikipedia is wrong. VRLAs aren't SLAs, and vice-versa. Actual SLAs are very, very expensive. All VRLAs can vent, by definition. VRLAs can overcharge and catch fire just like flooded batteries. They just don't go kaboom as much or spray acid everywhere. When having thousands of batteries in a room, one of them catching fire is inevitable. This is why batteries are in separate fire containment rooms, on nonflammable shelving, in redundant strings, and protected by FM200.
