I have a RT group 34R (primary) and a YT group 34 (Aux.)
~34R = reverse terminal~ (in this case, matches the oem config)
^ the standard RT 34 does not have reverse terminals and will require specific battery mount placement and/or extending the cables somewhat.
My RTR G34 is 6 years old...
and the YT G34 is around 5 years old.
bought the later used... fo $ 50.
was prolly already a year old.
I have to say... I prefer the YT
and as soon as my RT dies, it will be replaced with a YT.
I have never had issue with my batteries...
but have found that the RT does not appreciate sitting idle
as well as the YT does.
And my junk sits idle more these days, then when I first install the system.
IMO... many folk abuse their Optima batteries,
by running heavy loads attached to the side terminals on the G 34's...
and I would recommend against doing that.
Anyway... it's just my opinion...
but I don't think it's the battery always to blame,
when it comes to all the folks complaining.
More then likely... there's some human fault in that failure.
I've been purdy dang happy with my Optima's...
they have never let me down on the trail, nor anywhere else.
and see no reason to believe all the BS I read about them.
Here's my set up...
still working as good, as the day I installed it
RedTop 34R (reverse terminal)
YellowTop (Aux) Group 34
