2002 PSD Starting problems.
On a side note, while I was at Sams I noticed there were 2 different kinds of Blues. So I call Optimas teck support and ask the difference.
Body Types
1. Lite Grey (or a dirty white) = Deep Cycle
2. Dark Grey = Starting ONLY.
Top Typs
1. Red = Most common (only comes in starting and usually on the lower end of the CCA's)
2. Yellow (dark grey) = Heavy duty starting only and has the highest CCA's.
3. Yellow (lite grey) = Heavy duty Deep Cycle and to be used with a large # of accessories (High power stereo, lights, winch or duel winches front and rear)
4. Blue (dark grey) = Heavy duty starting only and has the highest CCA's.
5. Blue (lite grey) = Heavy duty Deep Cycle and to be used with a large # of accessories (High power stereo, lights, winch or duel winches front and rear)
ACCORDING TO OPTIMA THE ONLY DIFFERENCE BETWEEN YELLOW AND BLUE IS IN THE TERMINAL SET UP.
Blue = 4 top terminals. 2 standard and 2 screw shank style. These are called marine batteries because the screw shanks are for the trolling motors on boats.
Yellow = 4 terminals. 2 on top which are standard and 2 on the front side(female thread).
Both of these batteries come in starting and deep cycle.

Deep-cycle vs. Starting
What does deep-cycle mean?
Deep-cycle means using the battery in an application that will typically discharge 60% to 70% or more of the battery capacity. An automotive battery is an SLI (starting, lighting, ignition) battery. Its plates are designed to deliver maximum power for a short duration. Starting a car typically discharges an SLI battery only 1% to 3%. When an SLI battery is used in a deep cycle application, or in a vehicle with heavy accessory loads, the battery life will be shortened proportionally to how deeply it is cycled on a regular basis.
When should I consider a deep-cycle battery?
Any time you need the battery to supply all the operating power for a vehicle or other device. Additionally, deep-cycle batteries should be used in vehicles that have heavy accessory loads where the alternator cannot maintain the battery in a fully charged condition. Some examples include vehicles with powerful stereo systems, vehicles with increased electronics like GPS systems, game systems, DVD players and LCD screens or boats with on-board chargers, trolling motors, fish-finders, stereos, lights, etc.
