Power tools with lithium batteries: 3 reasons to choose them

A novelty in recent years is the introduction of lithium ion battery technology to power power tools. Why choose a power tool powered by lithium batteries? What are the advantages found in practical use? What are the differences compared to traditional NiCd or NiMH batteries?

The lithium batteries they have now become part of our daily experience thanks to the constant use that we all make of smartphones, tablets and PCs. In recent years this innovative and advanced technology it has also been introduced to power the engines of electric cars, once again proving its worth efficiency and effectiveness like other more traditional and well-known energy carriers.

Here you are 3 reasons therefore we recommend choosing power tools with lithium batteries:

• Better weight/power ratio. For the same weight, lithium ion batteries guarantee high power to the professional tool even at low temperatures; even some models weigh less than the 60% compared to traditional batteries, with the same power output.Better weight/power ratio for lithium batteries
• Complete absence of the memory effect. The memory effect for accumulators prevents the battery from being able to be recharged if it is not completely discharged, preventing, for example, the 60% from completely recharging a discharged battery; Power tools powered by lithium batteries are immune to this effect and can be recharged at any time without reducing battery capacity.
• Very slow self-discharge. Unlike traditional Nickel Cadmium batteries, lithium batteries do not lose significant charge over time and are perfectly usable even after months of inactivity; more precisely, the self-discharge can be estimated at approximately 0.1% daily.

A criticism that some make of new technologies it is certainly the highest price and the lithium batteries for professional tools they are no exception; however, considering the cost you need to incur to replace an old traditional battery compared to what you incur for buy a new product powered by lithium battery, it is this one is certainly more convenient second option; in fact, when purchasing power tools for the hobby, the cost is approximately only €20 higher.
