Optima Yellow Top YT S42 Battery Stinger Oddyessy XS Power Deep Cycle AGM ?

I have for sale a 2 x Optima Yellow Top YT S42 AGM Batteries both in very good condition. Neither have had heavy use, so its had a very easy life. Both batteries were used to test recently and is fully working, you may test on collection. These batteries are AGM deep cycle, that can be used as a startup battery or as a secondary battery. I ran over 1500 watts rms of class AB power from 2 amps and had no issues. they discharge and recharge very quickly. Reason for sale is yet another change in plans on the install im doing. So this is surplus to my requirements.
