Be careful ordering this model from Amazon. I did a search for the model number 12117TC and I found what looked like the same minder for the same price. But in reality it was 12117 not 12117TC and therefore no temperature compensation. I could only find the 12117TC for sale on the Northern Tool website. In fact when I went to the manufacturers website Batteryminders.com the model is not on the website for purchase. But when I typed 12117TC into the search box it shows up as exclusive for Northern Tools.
