This Duralast Gold battery came with a vehicle I purchase a little over a year and a half ago. Date on the battery is 2/2017. When I purchased the car I noted it was an Autozone battery but didn't think much about it. After having to replace a dead battery in my other vehicle I swapped the two batteries and suddenly realized that this battery doesn't have your typical "maintenance free" caps on it but what appear to be screw on caps for maintenance. I find it strange that this battery has these caps, should I have been opening this battery up to check the level inside the cells and add distilled water if need be? I do live in a hot climate (during the summer) so I'm guessing it couldn't hurt to take a look inside. Why would they sell a battery like this for a normal daily driver? I don't ever recall seeing batteries like this being sold at your typical auto parts stores.
