10.25"L x 6.88"W x 7.05"H

2000 max amps, 75AH

Reinforced Waffle case (does not require steel shell for under-hood use)

available I-bar system, lets you have up to 3 1/0 studs per terminal for multiple cable runs, amp connections, bus connections, etc...

I just got a pallet of them, $239 each.

here u go

Is that 75 Ah at 20 hour rate?

It should be. All I ever hear Scotty talk about is how they are the only guys who give true BCI specs. That would lead me to believe that they follow the C/20 rate for their AH ratings, but who really knows. //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

If i am not mistaken that is one hour. The test they use to determine the Ah is 20 hours long but the state is only for a hour. if it were 20 hours that means that you could play your 1k system for 20 hours strait with out charging your bat before the bat would die. That seems a little ambitious to me.//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

No you are misunderstanding the rating. If it is a 75AH rated battery at a C/20 rate, then that means that the battery was able to produce 3.75A continuously for 20 hours before reaching 10.5V.

That 3.75A of current would equate to about 50W give or take, depending on amp efficiency.

trying to see where i seen figures like that before.....

I understand how the test works but the rating 75Ah is for a 1 hour period ad that is what he was asking the 20 hours is just how they test t because it is more accurate.

No the 75AH rating is NOT for one hour. That battery will not give 75A continuous for an hour. If it did, it would be more like a 125AH C/20 rated battery. Why would XS rate it at a one hour rate when all of the other battery companies rate theirs at the 20 hour rate? Now if you said they used a 100 hour rate, that would make sense. That would inflate your numbers beyond the competition. Not that Scotty would ever do that.

If it was in c/20 then it would be called ampere-hours not hour the Definition of Ah is how much current in one hour.

A current flow for one hour measured in amperes (amps). Abbreviated "Ah" and commonly called "amp-hour," it is widely used to rate how long it takes for a battery to discharge. For smaller batteries, a milliampere-hour (mAh) rating is used. For example, a 500 mAh battery means it will release 500 milliamps of current at a specific voltage for one hour before it is discharged

If its not then I want to know what a D925 is rated in.... for real.

A pc2150 would EAT that for lunch and it is rated at 100 aH C/20
