FTZ battery lug crimper

Just bought this crimper to make new cables for my new invertor/charger. I figured it would pay for itself, when I expand my house bank down the road.

It came with no instructions, other than the settings on the handle. I assume I crimp down as hard as I can? Turn 90 degs and crimp again? It also came with a small screwdriver, allen key and allen bolt. No idea what the additional allen bolt or screwdriver are for.

I have one of these. Awesome tool.
Mine came with a little paper with instructions on how to calibrate the crimper prior to use.
I remember seeing another post about it here or somewhere else, I'll dig it up. The tools are to use in the calibration.

To crimp you just follow the guide on the handle for the lug size you are using, dial the right dies (left and right) and crimp - place one of the handles on the floor and hold the wire with the other. It does not need to double crimp unless you are using the double crimp lugs.

I assume you have seen this?

Good to know it needs calibrating. Nothing came in the box, I just double checked. If you have anything, I would greatly appreciate it.

Sure have. I purchased the crimper from the link in MaineSail's article.

Thanks again.

Re: FTZ battery lug crimper

I actually bought one of these. It has worked flawlessly and makes a nice 6 sided crimp.

Re: FTZ battery lug crimper

Since those hydraulic crimpers are always for metric wire sizes ("9x dies: 4, 6, 8, 10, 16, 25, 35, 50, 70mm2 ") they will not properly crimp SAE or AWG wire sizes, found in the US. And of course, everyone "in the business" in the US insists that properly sized dies are critical, that "close" is not good enough.

Leaving the question of why some clever Chinese tool maker doesn't supply US die sizes for the US market. (shrug)

Or, perhaps close is good enough and all the sized dies business is nonsense?

Re: FTZ battery lug crimper

I got the FTZ crimper per Maine Sails recommendations as well... along with the one he sells for heat shrink ring terminals.

Ordered some lug terminals from genuinedealz for 2 AWG that only says "pink die" on it. I set according to what's on the handle then did a crimp, but it seemed too small as part of the lug was squeezed out one side of the crimper, so I went to the next size up and had a better crimp. Same thing happened when I got a different terminal that only said to use "brown die" and had to re-adjust after the first crimp.

Certainly a good crimper for working on the boat and crimping terminals while the wires are in place. Not much room for the hammer crimper I have on hand.

I also got a piece of paper with mine, but just set everything to the side for now. Didn't see a need to use those bits at this time.

I have a similar one from Harbor Freight which works great on everything from battery lugs to the davit cables and dink security cables. 6 years and still going great.

Looks like your crimper needs calibration...
