Know Your Power Source

 Lithium-Ion vs. Nickel-Metal Hydride Batteries Part 2



Continued from November’s “Clipper Tip” article.


  1. Power: While Li-On and Ni-Mh batteries can store a similar amount of power at the same physical size, because Li-On batteries are lighter manufacturers like them because they can be made twice the size for more power without adding to the overall weight of a product. For example, the Andis Slimline Pro Li is bigger but lighter than the Andis Slimline Pro. However, the Andis Slimline Pro Li features a 2-hour charge and run-time compared to the Andis Slimline Pro which only has a 1-hour charge and run-time simply because of its battery properties. Another advantage of the Li-On battery is that cutting performance stays consistent, even when the battery is close to being completely drained.


  1. Durability: While both batteries are durable, proven technologies, the Li-On battery has the edge in terms of memory effect caused by charging – there is none. In addition, a Li-On battery may only see a 3% “self discharge” per month where energy loss with a Ni-Mh battery is much higher at 30%. Note that this is more of an issue for a consumer who might not use a tool every day.


After using all types of cordless tools, I’ve come to prefer Li-On powered tools over NiMh powered tools. In the salon, I have found that the Andis Slimline Pro Li and the Supra ZR detachable blade clipper best fit my needs. While I may fall short in my own personal charging habits, my Li-On powered tools perform as promised, withstanding an entire day of high-volume cutting. Best of all, they deliver the power of a corded product with freedom from a cord. This gives me the added benefit of performing faster haircuts because I’m not stopping to detangle cords. So if you are in the market for a powerful, reliable cordless tool, try Li-On battery technology.
