3.5Inch Battery Internal Resistance Tester
Overview
The battery internal resistance tester is a measuring instrument used to measure the internal resistance, voltage, and temperature of rechargeable batteries such as lead-acid batteries and lithium batteries to judge the health status of the battery.
It can also be used as an instrument to measure the ESR parameters of electrolytic capacitors. UT677A uses the AC 4-terminal test method to measure the internal resistance of the battery, which can measure the correct measurement value without being affected by the contact resistance between the test lead, the terminal, and the battery electrode.
The whole machine is high-grade and beautiful, with a wide range, high resolution, convenient operation, convenient carrying, accurate, reliable, stable performance, and strong anti-interference ability. It is an indispensable instrument for battery production, battery installation, equipment production, equipment maintenance, and other scenarios.

There were periods I was on the edge of my seat. There were times I just wanted to the book to end.
Format: Paperback
I recently started reading at 40 years old to make up for a lot of wasted time and missed education. This is a very informative read, but that said, I had a hard time staying focused sometimes. He gets into a lot of the science pertaining to plagues, epidemics etc which is interesting and I am reluctant to list science as a con as I did learn, but frequently found myself scrolling through several pages just to get the main idea behind the historical part. There were periods that I was on the edge of my seat and there were times I just wanted to the book to end. 1491 was similar. Both useful books, but a bit challenging to follow along especially if you are only reading small amounts at at time like on break at work etc. It jumps around from S. America, N America and China all through the book. I would have preferred that each region be separated. I get that he had his reasons. I am glad I read both books, but I probably should have gone with more of an overview vs the more in-depth content in this. I do not regret reading both books however, and recommend if you already have a good knowledge of this subject and are just trying to learn a little more. I found the information about the slave trade, the most interesting and wasn't aware that the majority of slaves shipped over from Africa went to Mesoamerica and the Caribbean. I also did not realize that plague and sickness really enabled use of African slaves as they were not prone to malaria like the Europeans. There is also some good info about ancient China and also sliver and mercury mining with South American Indians which made the book worth it for me.

If you liked 1491, you'll like 1493
Format: Hardcover
I originally read the first edition of 1491, which I loved. So that's why I ordered 1493. At about the same time 1493 arrived, I found out there was a new, revised version of 1491, which my husband bought from another source. So I re-read it at the same time I read 1493 for the first time. The reason I mention this is that there are some similarities between the revised version of 1491 and the newer book, 1493 - actually some repeated material. That's ok, as the author is taking the premise of 1491 another step further. Essentially, 1491 focuses on what new studies show was really going on in the Western Hemisphere before Columbus' arrival, where native peoples were far more numerous and had more advanced cultures than Europeans previously thought possible. In 1493, Charles Mann shows not only how Columbus and Europeans changed the New World, but how the "Columbian exchange" wrought great changes in the other direction as well. And he pulls in the further exchanges with Asia, to show the trans-global linkages of the phenomenon. So, some of his exposition gets a little repetitious, but overall he's an engaging writer, and for those of us who love the history of cultural exchanges and first contact, these books are mandatory reading!

Truly worth every penny. DS2r?
Format: Hardcover
Truly incredible documentation of the thoughtful work of a handful of artists. I'm hoping that by supporting this book we may inch ourselves closer to a Dead Space 2 remake lead by Motive studio. This book is a must for fans or the game and horror in general. Well made, good quality images, lore drops, developer letters. Its fantastic!

Great Art Book
Format: Hardcover, Format: Hardcover
One of my all time favorite games, this was perfect. It IS an art book, so more into the visuals then descriptions or thoughts on designs, but that's about what I expected. Especially as it's more for the remake than original. But still worth every cent, great to see the details (especially things that are tough to see in-game) and small descriptions. Arrived quicky and in perfect condition, no complaints at all!
