    Aquired Hawker SBS J13X. Need info.

    I acquired a Hawker battery from work the other day. Main reason why I got it was for the simple fact that is was a really small 12V battery. After a little bit of searching the recommended batteries seem to be Optima and Hawker. I like it because it is a soda can high and deep and three soda cans long. (Very technical measurements there...).

    Anyway, here's what it's labeled:
    Hawker SBS J13X
    MIL PCM546MJ

    NSN 6140-01-484-5342

    12V 12 Ah/C8/1.75Vpc/77*F (the 8 is subscript)
    Float voltage 2.27 Vpc @ 77*F

    Closest battery I can find is the PC 545. It has 545 CCA with 21 minutes of reserve @ 25amp load. Since the model is MIL PCM546MJ is think the MIL and M stand for military specs and the MJ stands for metal jacket. I also assume that it puts off 546 CCA. I know NSN is for the National Stock Number for government agencies to purchase it. I also think the thing is more made for motorcycles.

    Can this thing start my car or should/can I run it as a secondary (through an isolator). As secondary, it would run my inverter, 480W PSU, and two amps (480W & 720W). If you had this battery, what would you do with it?

    I am unsure how many CCA's are required to start your car. The PCM545 provides 230 CCA according to the specs.

    The Hawker oddyssey and genesis are excellent batteries to use as tanks as they have no restrictions (no max) on charging current. Just stick a PAC-80 in between your car battery and the tank and you are set.

    Where'd you find these specs. Here's where I found my specs: HERE. Says that the PC 545 does 545 CCA. I did see one another site that most of these batteries can produce double the CCA for the first five seconds of startup. Is this the number that I'm seeing (double)?

    The link I posted above is the manufacturer=). Here is the actual chart of this line of batteries.

    New info. My PCM680 just arrived with documentation that showed the PCM545 has CCA of 230; however, it also listed a parameter called 5 second cranking amp, which had a value of 545. Go figure=)
