I did some battery research.

As I understand it:

The Optima batteries are virtually indestructable, super-powered, long-lasting fast-charging, cutting edge spiral cell technology automotive batteries. The closest competitor using the same technology(spiral/leakproof/antivibration/etc) is Exide Tech's Select Orbital battery.

Exide batteries

The Exide battery is a Select Orbital and has 690CCA, 850CA and for the H3 the model# is ORB75DT-84. The dimensions are L 9-1/16" W 6-7/8" H 8-13/16
Lowest online price found was $114.95+shipping $20.00+ depending where you live @ remybattery.com
Optima Batteries

The Red Top battery is an SLI (starting, lights and ignition) battery to be used solely for starting applications.

The redtop that comes closest to fitting the H3 is Model 25 Size Category: Med-Small L9.25 x W6.3 x H7.7" Height includes 1" terminals It features 720CCA and 910CA Lowest online price found was $149.95 w/free shipping @1st-optima-batteries.com

The Yellow Top battery is a deep cycle battery for traction applications, such as winches, wheelchairs and similar electrical vehicles or for heavy duty starting of engines with a higher drain on the battery.

The yellowtop that comes closest to fitting the H3 is Model D75/25 Size Category: Med-Small L9.25 x W6.7 x H7.8" Height includes 1" terminals It features 650CCA and 810CA Lowest online price found was $172.95 w/free shipping @1st-optima-batteries.com

The Blue Top battery is a combination starter and deep cycle battery specially adapted for the marine environment.


So Red is Basic everyday daily driver use

Yellow is for offroaders/customzers with winches, lightbars, mega-amped sound systems that wanna run things with the engine off

Blue is if youre converting your H3 into a sealed submersible vehicle and are planning to storm the shores of some distant foreign land.

In the end...

The Exide battery with slightly lower amps may be the better bet as far as Price, Fit & Finish go

The Optima's if you want the added power, but be prepared to retro-fit your cooling box to make it work/look good.
