What truck batteries do you use and how long do they last?

Or buy an electronic load tester from Amazon for $20 and test your own batteries at your convenience, any time...

 

Ok got a clear head now, what I probably meant to get across was higher cca do have more plates thus more prone to warpage( when heated up ie: cranking for extentended periods etc) than lower cca batteries but not sure if a lower cca can handle deeper discharge than a higher cca. too much alcohol sure can make me stupid. I had 4 900 cca batteries in my Columbia and would run the espar bunk heater and kooltron fridge all night till I started having grounding issues but on that truck the batteries were behind the cab so there was almost 10 ft of 02 wire which started giving me problems

 

I wouldn't trust a 20 dollar battery load tester..

 

You need the $55 load tester from Harbor Freight. The $20 tester is only good for motorcycle batteries.

Your starter motor pulls 4 times more, probably higher, then that $20 load tester.

500 Amp Carbon Pile Load Tester

 

Electronic not a carbon pile.

. Works fabulously, what's not to trust, do you trust a $5 volt meter? Do you trust a $300 steer tire?

 

My test light probably has a bigger clamp than your load tester..

 

It's not the size of the wave driver, it's the motion of the ocean......

 

Those electronic battery analyzers are better as paperweights IMO. Seen them pass batteries that could hardly even produce half their CCA rating on a carbon pile.

 

curious, which odyssey amg unit did you buy and did you replace all of them?

the amg’s are massively stronger than the normal tractor batteries so did you need 1 to 1 all 4 or 4 down to 3 or 2?
