Biggest technology acquisitions 2020 | Computerworld

Published

on


Last year marked a slight decrease in global technology M&A activity from the blockbuster year that was 2018 – when SAP bought Qualtrics for $8 billion, IBM acquired Red Hat for a staggering $33 billion and Broadcom picked up CA Technologies for $18.9 billion in cash.

As of the end of Q3 2019, technology M&A deals worth $245 billion had been announced globally, marking a decrease of 25% year-on-year according to GlobalData.

Which mergers and acquisitions does 2020 have in store? If January alone is anything to go by then there will be no slowing of major deals across the industry, with security already proving to be a hot area.

Here are the biggest technology acqusitions of 2020 so far, in reverse chronological order:

March 26: Microsoft to acquire Affirmed Networks

Microsoft announced that it is acquiring the Boston-based Affirmed Networks for an undisclosed amount in March. The 2010-founded company specialises in virtualisation and cloud-based mobile network technology, which makes it an attractive acquisition target for any company investing in next-generation 5G connectivity.

“This acquisition will allow us to evolve our work with the telecommunications industry, building on our secure and trusted cloud platform for operators. With Affirmed Networks, we will be able to offer new and innovative solutions tailored to the unique needs of operators, including managing their network workloads in the cloud,” Yousef Khalidi, corporate vice president of Azure Networking wrote in a blog post.

The terms of this deal were not announced but Affirmed was most recently valued at north of $1.3 billion following a $38 million funding round in 2019.

March 2: BMC Software to acquire Compuware

Enterprise software stalwart BMC agreed to buy Compuware in March for an undisclosed amount, marking its third purchase of a mainframe specialist in just over a year.

Energizer Universal Rechargeable batteries offer the best balance of power and price that we could find.

How We Tested

All batteries were completely charged before testing began.

The Tester

I’m Richard Baguley, and I have been testing and breaking technology for over 20 years. In that time I have tested everything from automatic coffee makers to wearable computers. Until 2012, I was the VP of Editorial Development at Reviewed.com, where I created the testing protocols that are still used for products such as TVs, dishwashers, coffee makers and refrigerators.

The Tests

The most important things about rechargeable batteries are how much charge they can hold and how quickly they can deliver it.

So, we tested them by doing just that, using two high-end rechargeable battery chargers (a La Crosse BC700-CBP and a SkyRC MC3000) to measure the amount of charge that each of the batteries could hold, testing four of each and averaging the result. We tested AA batteries as these are the most commonly used size for modern electronics such as TV remotes, as well as some smart doorbells and outdoor security cameras.

To see how long the batteries in our test group would last, we used them to run two devices: a small battery-powered fan and a powerful flashlight. Drawing 0.6 and 1.4 Amps, respectively, these devices allowed us to measure how long each battery can run during low-drain and high-drain use. For these tests, we ran our fan at maximum speed, recording how long it kept rotating. Our flashlight was operated at maximum brightness—roughly 350 lumens—as we recorded how long it stayed lit.

To calculate how long the batteries would last, fans were left running until each battery died.

When the blades stopped turning, the time was noted and the test was stopped. In instances where I had to step away from observing the test, I set up a GoPro camera to record the operation of the fans, just in case one stopped running before I got back.

What You Should Know About Rechargeable Batteries

Rechargeable batteries are pretty simple devices, but there is a lot of jargon surrounding them. Here’s our guide to the things you need to know to make an informed choice.

  • NiMH: Nickel Metal Hydride. The chemistry inside the battery that stores the electrical charge. One side of the battery is made of Nickel Oxide Hydroxide, and the other is made of an alloy of several rare earth metals. When the battery is charged, the Nickel Oxide Hydroxide gives up a Hydrogen ion, which is absorbed by the alloy. When the battery is used, this is reversed, creating a flow of electric charge out of the battery.
  • Charger: the device that controls the flow of charge into a battery. You should never use a NiMH battery (like the ones in this guide) with a non-NiMH charger, as this can damage them.
  • LSD: Low Self Discharge. All batteries lose a certain amount of charge over time, even when they are not connected to anything. This is called self-discharge. Typically, a NiMH battery will lose up to half its charge if stored for a year. Some batteries minimize this by adding extra insulation inside the battery.
  • mAh: milliamp-hours. A measure of the amount of charge that can be stored in a battery. 1 mAh is a flow of one milliamp over an hour, so a 2500 mAh battery can deliver 2500 milliamps (or 2.5 Amps) for one hour, or 250 milliamps for 10 hours.
  • Cycles or Recharge Life: Each full charge and discharge is one battery cycle. All batteries lose capacity when used, meaning that they can store a little less charge with each cycle. Manufacturers offer a cycle life, a number of cycles that the battery can go through before it loses a certain amount of its capacity. This is defined in a standard called IEC 61951-2.
  • Other Sizes and Adapters: We focused on rechargeable AA batteries for this guide as they are, by far, the most commonly used battery size. They can also be used to power devices that require C- and D-size batteries, too. All you have to do is pop them into an appropriately-sized adapter and you’re in business. This adapter set from Eneloop is a great option for anyone interested in doing this.

Other Rechargeable AA Batteries We Tested

Checking our work.

We use standardized and scientific testing methods to scrutinize every product and provide you with objectively accurate results. If you’ve found different results in your own research, email us and we’ll compare notes. If it looks substantial, we’ll gladly re-test a product to try and reproduce these results. After all, peer reviews are a critical part of any scientific process.
