This 6V VRLA battery has exactly that, three cells and you can see three blue caps of the three cells here. You can see that everything is quite dry and there is no escape of liquid from the region of the caps.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>VRLA or Valve Regulated Lead Acid batteries are also known as Sealed Lead Acid Battery and Sealed Maintenance Free (SMF).
