In a matter of 3 months I killed an Odysse PC625 by charging it incorrectly every single day.
It takes less and less charge, until it's worhtless.

Odyssey isn't a gel battery. It's a plain old sealed lead acid battery.

Dude the Odyssey is a AGM battery, that is why it is called a Dry Cell battery. There are three types of batteries that you will most commonly see in motorsports, and they are all lead acid varieties. 1. Lead acid with liquid electrolyte 2. Sealed Gel with a gel electrolyte and 3. AGM with the elecrolyte absorbed into a glass mat. The latter two are recombinant in that they will only gas if overheated or overcharged. This is why they die prematurely mostly due to improper charging techniques. Here is a page from the Odyssey tech manual FAQ section from their website, checkout where it answers the question on how the Odyssey differs from a gel battery.

What was your point? I said it's not a gel battery.
It's a sealed lead-acid battery. (AGM falls into this category)

ok here is a question for every one
want do you want in a total loss ignition
I am debating at the monet if to use the msd flywheel and pickup
as i figure there is alot of guys out there already with this stuff and it would retro fit your old gear

wax, Keep in mind , there are 2 differant MSD TL set-ups. Single trigger & Duel Trigger......... Duel uses 2 seprate coils. Flywheel & stator(pick-up) plates are differant.

i was just trying to ring you again paul to ask you this

ok i will pass on that idea then
was trying to figure out a way to use all those old flywheels sitting around

Not trying to argue, just pointing out that a gel battery is a sealed lead acid battery and is similar to a AGM in that it uses recombinant technology. I saw your post about killing a PC625 Odyssey AGM in 3 months. I posted the links thinking that maybe you were overcharging it with too much voltage or constant current. Either of which will kill a gel or AGM quickly. I personally would not want to keep buying $90 Odysseys if you could avoid it. Its all good, just trying to help. :biggrin: I have a local guy who can get some AGM PWC batteries for $50. I have been running them for over a year now with no problems. They will pulse 800 amps to crank the crap out of a hi comp engine.

Matt E the total loss will use the same sort of ignition box as i am selling on here with just a few small inner circuit changes

thats bit has already been done
its the machining of the flywheel i am working on now and the right pickup
the one i have at the moment is to big and i want it to be smaller so i can make the flywheel lighter

Eh? I am confused....I am well aware of why I killed the battery...I thought I posted that.
I used the wrong charger. Constant current, with high voltage = bad juju for Odysseys. I thought I'd made that clear.
And Odyssey is not a gel-type.

EDIT: I did post it. Did you not see it?

4.) Battery not taking full charge? Did you charge it properly? Yes, that's important. Oddyssey batteries need to be charged a certain way, especially if you'll be doing it every single day for months at a time.
Oddyssey calls for a non-constant-current type charger. That means DON'T charge it with these 2A/10A/12A chargers. Those put out a constant current, which damages the Oddysseys after a while. Also, the output voltage should be between 13.6 and 14.5 volts, and no more!
The newer automotive chargers often go up past 15.5 volts, and that will kill the Oddyssey battery over time.
The ideal charger will put out 13.5-14.5 Volts, start at about 10-12Amps for a nearly empty battery, and slowly go down to 0 Amps for a full charge.

Yeah, well duh, I just back tracked the thread and saw that on page 1. Sorry for the mix up. Did not mean to jack the thread.

Does the dual trigger unit fire each plug independently using different pickups or is there another reason for dual as opposed to a single pickup? Just wondering..
