2.5l d22 navara cranking amps

[Navara09]

Hey guys just wondering if anyone knows what th cranking amps of the 2.5l d22 is?

Mines a 90A alternator, I think the ZD30 boys run a smaller one.

Mine is an 08 Jap build so pays to check yours if it's an 09/10/11 Thai build.

 

[Navara09]

So if mine is the same i will need 90A? or can i have less or more

 

[Jason]

Ah, you want to know the CCA rating of the battery?

I thought you meant Amp output from the alternator.

at a guess, with a cold engine start, (I'll test it one day and post it) I would say roughly 'tween 250-400 amps.

 

[Navara09]

yeah sorry the cold cranking amps? or where can i find it

 

[Jason]

This is in the manual.

Do you think that the above is indicating that the Thai models with dual batteries are for cold climates?

Interesting.

Oh, ok...since you didn't mention the batt, it seemed you wanted to know how many amps drawn at cranking (by the starter).

that what it looks like..

though thats showing the amp-hour rating not cca.

 

[Navara09]

ok thanks for that jason. yeah i want to know because i am putting a dual battery system in and i just want to make sure the one battery is big enough for when i switch the other to a deep cycle

Just an added note.

As a rule you can't readily convert from AH to CCA as a lot of the CCA rating has to do with battery construction. But there is a couple of formulae that will give you an approximation.

Take the 75AH as an example. To convert to RC (Reserve Capacity) subtract 16 and multiply x 2 ( (75-16) * 2) = 118RC. CCA is approximately 5 times RC so 118 * 5 = 590 CCA.

Thats handy to know....

In another thread, with pics, someone mentions replacing the standard battery with a bigger battery when he did something similar. Dual battery thread?
