These are excellent top post battery terminals. I've bought two of these kits and both have been high quality. They work great for wiring a winch or other aftermarket electrical accessories that need to connect directly to the battery because you can place large ring terminals on either side of the through bolt, allowing more space to add wires. The use of ring terminals for the individual wires also allows you to easily disconnect the battery without removing the lead terminals themselves. This will help make the lead terminals last longer, as repeatedly removing them from the battery posts deforms the lead and eventually reduces the capability of the terminals to clamp the posts.

This kit includes everything you need to wire in the new terminals, including four crimp on ring terminals for your battery cables, heat shrink for the ring terminals, bolts to attach the lead terminals and battery cables, and nice rubber covers that are color coded. All of the hardware is high quality. The ring terminals are too big for normal crimps, so you will either need a set of battery cable crimps, or use vice grips like I did (not ideal but works, and you can cover the ugly crimp with the heat shrink...)

Reviewed in the United States on April 7, 2017
These are a huge upgrade over just about anything else factory out there, and if you have extra accessory wiring direct to the battery they do a much cleaner and more secure job of it than standard terminals. In the past I've bought batteries with side and top posts to use the side posts for accessories but the problem is these days the side posts are not made very well and the threads strip over time if they are used often even if you are careful. They are quite a bit more secure, and made of harder material than standard terminals, they still conform to the post very well but you can actually tighten them without worrying about splitting the clamp as many cheaper options have issues with if they are used frequently.

The only thing to be aware of is that these are large terminals and with some batteries you may only be able to mount them in one direction which can limit the options for installation and possibly require additional re-wiring. This was the case with my S10 blazer where the negative side of the battery is partly tucked under the rolled fender where it meets the hood. The factory negative wire comes across the top of the battery at an angle to the post, however with my battery these clamps had to be positioned 90 degrees to the length of the battery (My X2 Power battery had a recessed area for the clamp but due to the extra size of these clamps there was no ability to rotate it unless it was higher than the recessed area on the battery which would then compromise the clamping to the post) so I had to re-wire the negative wire for some extra length and it complicates getting the negative clamp and accessories on/off. That's more of a battery/application specific issue than a knock against the product it's just something to be aware of.

This kit was more expensive than it would have been to replace the OEM parts, but it was well worth it. I purchased this to replace the terminals on a 2001 Tacoma with the 3.4 V6. The kit is complete, you'll just need to remove the old terminals and then 1/2" and 9/16" wrench to tighten things down, a crimper, and something to heat shrink the included wraps.

The install was straight forward enough. I'm not sure if my terminals had been replaced before, so I had just enough wire to make the replacement. It would be nice if the kit came with a couple of smaller gauge crimp connections that will still bolt to the terminal, as I had to mock up a connection for the ground wire.

All in all, between the crimp connections, the heat shrink and the heavy-duty rubber covers, this is sturdy, well-made hardware that seems like it'll last longer than my truck will

Reviewed in the United States on September 12, 2016
These are a huge improvement over the worn-out factory battery terminals on my 1999 Jeep TJ. The new terminals grip both battery posts tightly and will easily accommodate additional ring terminals for accessories such as a sub-woofer, auxiliary lights, and a winch. I did purchase smaller copper lugs for the relatively small (6 AWG) factory battery cables in the Jeep, but I've read that the included hardware will work when soldered onto the cables.

I wish that I had bothered to read more reviews before I began my installation as a Dremel tool or hacksaw would have been a much cleaner option to free the cables from the old terminals. I applied heat with the intent of softening the lead and pulling the cables, but the old terminals basically melted instead. I started the process using MAP-Pro fuel in my torch, but after seeing what the heat did to the old terminals I switched to propane before soldering the lugs onto the cables. Remove the battery and use something like aluminium foil to catch the molten lead/solder if you decide to go this route.

The heat shrink and terminal covers are nice finishing touches. I'm very happy with the end result and so far the Fastronix terminals appear to be a significant improvement over stock.

Was nervous looking for new contacts that would be of good quality and not be dependant on hex screws to hold down a connection like some other products available on Amazon. These are very good quality. Used them on my 2004 Acura TL. Fit great and they have great clamping force. Lots of room to add accesories, and you dont have to disconnect the main to access any accessory wire you may be adding or removing. Nice that they come in different sizes for + and - as that is a common complaint with other products that theyre the both size, not the case with these they are proper size. The rubber covers are awesome too ! Very satisfied and would recommend
