Welcome to TechMoment.net – Your place to learn about Battery Technology
When it comes to consumer level lithium-ion batteries the 18650 battery is almost irreplaceable. In this article, you will learn everything you need to know about choosing the lithium-ions in general but with a focus on the 18650s. This absolute guide will also review the top 18650 batteries for various use cases.
The AA battery is the most commonly used cell for regular household use. There are various chemistries to choose from. Alkaline, Nickel-metal hydride rechargeable, lithium non-rechargeable, lithium-ion and a few others. In this article you will learn what are the top AA batteries and for what use.
While not a battery this article needs to be listed here at the top. Rechargeable batteries and chargers are almost a non separate entities. You can’t have a good performing battery with a junk of a charger. In this article I wrote about the highest quality battery chargers for 18650 cells but these chargers are excellent for almost all cells and chemistries.

Lithium Iron Phosphate (LiFePO4) are very different from Li-ion batteries even if they are a type of a lithium ion battery. They have a significant difference in cycle life and safety but other advantages and disadvantages as well. In this article we will first define which li-ions are we comparing to LiFePO4 and then take an indepth look through easy to understand graphs.
Nickel-Metal Hydride is a more advanced cell when compared to NiCd but there are still some cases when NiCd outperforms it. In this article, you will learn why the NiMH is the obvious choice for most use cases and especially in regular consumer electronics. You will see the graph comparison of individual battery characteristics to better understand these two battery chemistries.
This is an online battery charge time calculator that allows you to input your desired charge efficiency level. It is a very useful tool as it let’s you calculate a somewhat complex mathematical process in mere seconds. It outputs the charge time in decimal values and in the hours and minutes value. It works best if you know your charge efficiency but if you are not sure you can use the default value.

I made this website to help regular people learn about battery technology and get the right battery for their needs. On this blog, you will read about different battery chemistries, battery limits and purposes, what constitutes a quality charger and of course which battery is right for your particular needs.
When it comes to regular household batteries you can make a mistake and get the wrong chemistry for your purpose. Not a big deal. You will just probably waste a few cells more than you need to. But with more complex cells like Lithium-ions, Li-Pos, LiFePO4, NiMH and similar of various sizes you should know what you are doing.
Even with regular household batteries like AA and AAA batteries you should pick the proper cell for your needs. It is wasteful to keep constantly discarding alkalines if you can use NiMH (in 99% of cases you can).
So as you see batteries are a bit more complex.
You can’t use just any cell for whatever drain. Your cell needs to thick a lot of the boxes on the list and especially the CDR rating, matching battery with a proper environment (temperature and other conditions), cell size and weight and etc.
On top of that, you will need a good charging system. Getting to know how different battery chargers work is very helpful. Why would you want a charger that tops off your battery constantly? Or why should you get something that doesn’t utilize negative delta-V? This all of course depends on the chemistry of the battery you are charging. You can learn more about it on this blog too.
The world is adapting rapidly to the new emerging battery technologies. The EVs, the whole network grids relying on battery power, solar energy storage, small portable devices and etc. All of this is changing our world and before you know it a significant portion of elements we base our life on will be battery powered.
It is wise to get on the wagon and learn about battery technology now. If for no other reason then just because it is fun and you will be able to utilize your battery-powered consumer electronics way more efficiently!
