What does the upgraded alternator / battery look like?

[Htfan]

I have read that a group 94 size battery fits, those have 800-850 cca.

Here's a good thread on this:

I'm going this route after the factory battery's lifespan is over.

Are you going to delete the aux battery ?

The tazer has a winch mode but again We dont know how much its putting out, we all have different needs, i would like 170amps at idle which is 500rpms and that seems doable either the mechman conversion or ordering the jk 250 alternator from tuffstuff, anyone knows if a 2018 jk alternator fits a 2018 jl ?

Yes, I'm considering deleting the aux battery when it dies (again). However, I also noticed another great thread with DIY instructions on replacing the aux by removing the plastic passenger fender flare. It's fairly quick and easy.

Didn't the towing package used to come with heavy duty cooling as well? Bigger fan and/or radiator?

The charts are generic, and posted for illustrative purpose. They are not documents of measured performance. As per convention, the rpm axis would be intended to describe the spin rate of the alternator shaft.

That would make the pulley look smaller.

Also, looking at the pics...the COO's are interesting.....my 240 is Made in Japan....the 220 shown, Mexico

Quality no matter where it’s made..... right?!?

On the ones with 700 Amp battery for the ones with Tow package, is there only one battery or is the smaller ESS battery still there?

I have the tow package on the 3.6L ESS and it has the Aux battery. MY 2019
