So how are they used? in addition to, or instead of a battery? If 'instead of' how many 'shots' do you get at starting a motor which, for whatever reason, is being hard to start?Quote:

I will do up a thread soon to avoid thread-crapping this one but basically used in conjunction with lead-acid battery (much smaller now). The end result is huge amounts of current that can be released instantly with very little volt-drop resulting fast crank and starting.
The size I have should crank for about 15-20 seconds on a ZD30 without lead-acid battery connected.
Also how long would it take to recharge?.Quote:

EG in sound system,
or multiple power windows operating at the same time?

- They can discharge in the multi-kiloamps area, 2-gauge would be wise.
- See above, in my audio days, we used to use 1 farad "stiffening" caps for systems, these are WAY bigger, you will figure out what they will do for a decent sized amp.
- Can't help you with electric windows unless you have upgraded ALL the wiring, I am yet to see a vehicle with decent wiring that doesn't suck.
Personal preference only for $$ & Longevity :-) Optima Red Top for 'Crank' & 'Yellow/Blue' for auxiliaries, same/same I believe? Damn things keep going and charge as quick as;Quote:

Optima make good batteries from my experiences.
The best battery I have years ago in my VS SS 5.0L was a 13-plate Odyssey. Those suckers lasted forever.
I use these in the Patrol and the boat both for starting and for house

My Century Overlander was 4 years old when I replaced it with an Optima Yellow Top earlier this year. It was still cranking but was down on cranking capacity after testing. I got a decent deal on the Optima and decided to change it over.
i hope the Optoma lasts though as a couple of months later my second battery (Deka Intimidator AGM) expanded and died. It was only 3.5 years old. The turbo cooked it. I am a bit nervous now about putting the optima under the hood but it's good to read on this thread that they seem to last. When I removed the battery and tray I went for a short drive so that the car came up to operating temp (86 deg Celsius water temp) and then opened the bonnet. You could really feel the radiant heat from the turbo. On the other side of the engine the crank battery was only warm to the touch. I hope my optima lasts 7 years plus.
