Default Top Post Battery Conversion Q's

I need a new battery and am sick of trying to move things around so I can get those tiny screws into the battery from the side. I want to convert to a top post battery but have a few questions.

1. Would I need to replace any stock wiring?
2. Can I cut the stock wiring and just use a top post harness?

Have you tried looking for the side-post battery tool? You can get a special ratcheting wrench that will get that on and off easily. Would be easier and cheaper then trying to change your harness.

I haven't tried that yet. I would like to convert it because I've already butchered the rubber to accomodate the stereo wiring.

I was wondering if I could cut off the existing connector and replace it with one of these for each side and buy a top post battery.

Sears and Autozone are the only ones I know of that carrry a top and side mount on one battery still.

I converted mine to a side because of the stereo,air ride,etc. I just cut the ends of the wiring and bought copper plated ones at the hardware store. It gets better voltage, looks much cleaner and is actually cheaper to do.

They make adapters for that,

battery side to top post adapter



They are about $6.00 a pair at Auto Zone.

interesting adapter. i never bother to see something like that. as long as the wire is long enough to reach over it's not so bad. only thing that bother me is the positive terminal is exposed so much so unless u gonna tape it to protect any ground from touchin it, its a bad idea.

We used to call these

"leave me sitting" battery terminals, because they often develop corrosion where the cables attach and lead to a no-start. My truck has these, and when I replaced the battery I took them off the battery cables. The cable ends (between the strands of wire) were full of corrosion and battery acid residue. Took some scrubbing with baking soda to get everything clean again. If you're replacing the cable ends, I strongly recommend you use crimp-on or solder-on ends. Here's a how-to video on soldering cable ends:

As far as dual-post (top and side post) batteries, I know Deka tried them a few years ago. We carried them in a shop where I worked. I thought they were a great idea, but Deka had nothing but trouble with them. For some reason, the connections to the dual posts would fail internally. You'd test the battery using the side posts and it would test bad, then you'd test it again using the top posts and it would test good. Drove more than a few people (including me) nuts. Probably no longer an issue, but something to keep in mind if a dual-terminal battery gives you trouble.

I've never had trouble with the top-post to side-post adapters, but as someone else pointed out there is a lot of metal hanging out there waiting for a short. It is a good idea to cover as much of the adapter as possible with tape as suggested. I'd also put a film of grease on each electrical connection (adpater to battery and adapter to cable). There are special greases that are designed just for battery connections, but I usually use plain old lithium grease or petroleum jelly. Wipe off any excess to keep it from attracting stray dirt.

I have a dual top and side post in my 1 ton and it works great. I have everything from the truck connected to the top posts and the inverter that I run connected to the side posts.
