So easy to fit. Such a good value.
Got these so I could easily and quickly disconnect the battery on my 79 Triumph Spitfire for when it sits unused for extended periods of time. Kit came with a terminal wire cleaner, the negative and positive quick disconnects, allen wrench, and several negative and positive accessory wire connectors. This was a great value.

I only needed to replace one terminal.
I've never replaced a battery terminal before, but after watching a video on youtube, I thought it was something I could manage. So I ordered these. The price for 2 is inexpensive, the one I used is working with no problem, and
I have a spare in my toolbox.

3.0 out of 5 stars fair quality - great value - screw/post falls out
Reviewed in the United States on December 19, 2022

I bought the two pack - (comparing price for one at the local auto parts store).
These bend open easily for the positive batt terminal. The nice feature is the color coded whereas the local store is not colored, but local store is built stronger.
As previous read, the bolt does indeed fall out. Not a big deal if you don't frequently remove connectors from it. Having color terminals is worth that extra validation for polarity especially at night

These things are horrible quality.
The nuts at the bottom fall out. They didn’t make one for both sides so it can’t be tightened properly, tried tightening it and it bent. Returning and will invest in a more quality solution.
