New Battery Technology and the Use of Ceramic Batteries
By: Simon Høxbroe, Sales & Marketing Director
Our new CookPerfect True Wireless thermometer comes with a new type of battery, which has never been seen in the thermometer business before.
In this blog post we introduce you to the new type of battery that has a better and more sustainable technology that so far has been seen in wireless thermometers.
Why not True Wireless before now?
As Sales and Marketing Director, and Customer Manager in CookPerfect ApS and CookPerfect USA Llc. have I often been met with the question: “Why did you not make CookPerfect (Comfort) true wireless? Meater was able to do that years ago.”
The answer is simple: It is absolutely no coincidence that CookPerfect Comfort was born as a Bluetooth thermometer, and not as a “True Wireless” thermometer. We did not think that the correct battery technology was available in 2015, when CEO and inventor Martin Kloster began constructing the CookPerfect technology with 5 measuring points and the complex algorithm.
Let me elaborate: We acknowledge that the idea behind e.g. Meater is recognized as the first “True Wireless” thermometer on the market, which is great. However, we do not support using lithium batteries (lithium ion from the common supplier of this battery type) in thermometers, because of the many issues that come with this type of battery technology.
Lithium ion batteries are still used in many products on the market today, and for us, this is incomprehensible!
The issue with lithium batteries
A significant limitation to lithium ion batteries is that they are only approved to use up to 70 degrees C / 158 degrees F from the manufacturer. If the batteries are exposed to heat above this temperature, you risk that they leak poisonous fluids – or even worse, will explode.
You may be thinking: 70 degrees C / 158 degrees F does not sound as much – my barbecue is often 250 degrees or more! The batteries are inside the probe (the sensor in CookPerfect’s case), which is inserted in the meat. The meat often has to cook until it reaches approximately 58 degrees C / 136 degrees F. And in this case, there is no problem!
However, if you have to cook a chicken, it has to reach a minimum of 75 degrees C / 167 degrees F in order to be done. And with many slowcooking techniques the meat is cooked up to 94 degrees C / 201 degrees F.
With these high temperatures it will be irresponsible to use the mentioned battery technology. The same if you use a rotisserie and the sensor by accident detaches and falls into the coals.
The solution is the ceramic battery
CookPerfect will not use technology that we find irresponsible to expose to high temperatures. A state of the art thermometer must be able to withstand the high temperatures in a grill, a kamado or in the oven.
In order to manufacture a thermometer that can withstand the high temperatures, and can live up to the high standards of CookPerfect, we have looked elsewhere for other battery types. The ceramic battery is a so far unseen technology in the thermometer business.
CookPerfect is the first manufacturer of food thermometers in the world to enter into a strategic collaboration with a battery manufacturer of ceramic batteries. Ceramic batteries are so-called “dry batteries” that have far many more advantages than e.g. lithium ion batteries.
The pros and cons of the new Cookperfect true wireless meat thermometer
|The pros||The cons|
|Approved up to 100 degrees C / 212 degrees F||It is first when the batteries are exposed to degrees between 100 – 125 degrees C / 212 – 257 degrees F that the batteries start to decompose.|
|Contain no poisonous fluids that can leak||If ceramic batteries are exposed to temperatures above 125 degrees C / 257 degrees F then the product will simply just stop functioning.|
|Non-explosive||The batteries will not explode or leak poisonous fluids – as opposed to lithium ion batteries.|
|The batteries are typically smaller, which allow CookPerfect to construct the thinnest sensor on the market within the “true wireless” category.||The time it takes to charge ceramic batteries are marginally longer than with lithium ion batteries.|
|The ceramic battery has less impact on the environment|
There are practically no negative elements connected to the ceramic battery.
However, in the temperature range of 85 – 100 degrees C / 185 – 212 degrees F it can be expected that the total time of life is limited in relation to the total time of life if the batteries are not exposed to these high temperatures. However, this is not really an issue, because the batteries will still be used in many years by regular use.
What you get using CookPerfect Wireless thermometer
With a CookPerfect Wireless thermometer you really get the flagship of thermometers within the “True Wireless” category.
The patented CookPerfect technology with 5 measuring points in the sensor, ceramic batteries that can withstand heat, built-in Wi-Fi, Bluetooth and Cloud function makes this thermometer remarkable. You also have the ability to get 2 sensors to one base, and you have direct access to CookPerfect’s customer service directly from the app.
In order to help you take extra care of the ceramic batteries we have built-in temperature alarms in the CookPerfect app. The app will then notify you if you reach a temperature range that can damage the technology.
You will also be notified if the sensor has to be recharged after cooking. In that way you will never come back to a discharged sensor the next time you have to cook a meal for your guests or family.
