House Battery Connectors

I am in the process of replacing my six (6) house batteries and noticed that the old batteries have an upright connector with the bolts horizontal (see photo). The new ones (top photo Trojan T-105) have a single vertical stud. Is there any technical problem with switching? Not sure why the OEM AGL batts were configured this way.

Not really any problem. Clean the lugs on the cable ends well. Use a wire brush. Coat the cable ends, studs and nuts with CorrosionX or a electrically conductive grease. Find out what the torque spec for the studs is and tighten nuts to spec.

Thank you.

I can do all but the torque. I have no source for a torque value for the terminals. I wish that FT had done like Mercedes-Benz and published a master torque valuse table for every connection.

Figure out what the nuts and bolts are made of and determine the size and thread pitch and research a chart and use those torque values.

This should help.

Thank you craneman—Ironically, I had looked at that Trojan tech page when trying to figure out the differences in battery connectors. Missed the torque values. Many thanks!

You might want to consider switching to military or ordinance style connectors on the posts. The studs have been known to slowly creep up out of the posts, after all they are just steel studs set in soft lead.

Now that I posted that, yours looks like a shorter sturdier design. They may not have that issue.

I like the robust style of the military terminal, where is a good place to start looking for these? Other than online.

Replaced all of mine at the local "Interstate Battery" distributor. Also there was available a difference between - and + terminals., size of opening, not just markings.

Found 5 pair +/- at a battery shop 15 miles away.
$4.50 each. Kids at the oriellys counter are too frustrating JMO.
