are you sure? (legitimte question)

I always thought blue was just a yellow with extra terminals? (same price as a yellow so why not go blue for the convenience? if there is a difference I will re-think purchasing a blue to go parallel with my yellow and gran a second yellow.

but all the same another vote here fro the Optima Yellowtop, though don't look past an Amaron if you have no need fro deep cycle, my Amaron has been discharged to 1.5v when I lent my old 4wd to a friend (he left the lights on for a week without using the car!) that was 2 years ago, the battery wont fit in my defender (too big) but it sits on trickle charge in the garage and is used to jump start the mower and finds itself in the back of my fathers wagon to run his fridge for a week without charging, coem back gets put on trickle charge, keeps going, and the other week I had to shoe horn it into the odl commodore (my defender was at/still is at the dealer) and used fro cranking duties for a few days and help up fine, load test it and tests 100% and at half the price of an optima for more capacity (its 900CCA) worth while taking a look at, it is AGM also.

1 more for the odyssey PC1400.I ran it for years and it will put up with the winch no worries.

I run a Century 86zmf as my main battery.

It has 950cca and I think 120ish AH

Also pretty cheap and easliy available from Battery World.

I know I've seen yellows with the extra terminals (the female threads for a bolt in).

To clarify, from the Optima PDF's

Bluetops; Type 34m, starting only. D27m, D31m & D34m Starting and deep cycle.
Yellowtops; All types warranted for starting & deep cycle and vehicles with large accessory loads.
Redtops; All types warranted for starting applications only.

Maybe off topic, but I have a yellow top as a second battery in a dual battery setup with a sidewinder dual battery system and I find it rubbish.

I only use it for the fridge and I can drive all day (7am to 5pm) the led flicks on when my oem varta is charged about 20mins after driving so the yellow top should be getting charged and by 9am in the morning the fridge alarm is on and the battery monitor is at 11.5v.

Maybe there is something wrong with my system but I think the $350 I spent on the yellow top could have been better spent.

So I would not buy another unless I find something else is wrong other than the battery.

I think that it could be an issue with the charging system/method. Tim (Drivesafe on here) may have some suggestions.
