MAKITA 194204-5 2 x 18VOLT 3AMP LITHIUM-ION BATTERY (PACK OF 2)

 

Lithium-ion, the battery has evolved.

 

The Makita power tool range is a blend of tried and trusted products, together with some valuable innovations, carefully selected for the demanding needs of professional users.

 

 

Makita cordless drills are among the best in the world.
No effort is spared to ensure that our tools provide the professional user with reliable, long lasting power.

 

Makita’s Lithium-ion tools have proved market winner and now Makita’s expanded range offers a comprehensive, powerful and lightweight selection of professional tools to complete any job. Uncompromising on engineering excellence the new Lithium-ion tools offer the same attention to detail and quality you would expect from any Makita tool.

 

The long-lasting Lithium-ion batteries are 40% lighter than a similar Nickel Metal Hydride (Ni-MH) battery. Lithium-ion batteries feature a high energy density technology that will deliver 430% more working capacity during the lifetime of this battery compared to traditional Ni-Cad batteries. Lithium-ion batteries have an extended length of time during which they hold their charge – even after a long period of storage the batteries will deliver their power.

 

The most immediate difference between Lithium-ion batteries and Ni-MH or Ni-Cad is the weight difference this is achieved due to two factors: chemical composition and physical attributes.

Within a Lithium-ion battery the energy is stored through the movement of lithium ions. Lithium has the third smallest atomic mass of all the elements, giving the battery a substantial saving in weight compared to batteries using much heavier metals.

The energy density of lithium-ion is typically twice that of the standard Ni-Cad therefore less cells are needed to obtain the required voltage, this is where the main bulk of the weight saving and compact nature of the battery occurs.

The weight saving means that Makita can obtain 18 volt power from a battery weighing the same as a 12 volt battery.

 

Reducing weight whilst retaining power has obvious effects on operator fatigue. Working with a Lithium-ion tool will reduce fatigue due to the weight of the battery pack this in turn will have positive effects on site health and safety.

The design of the battery is a slide grip type giving a maximum and secure contact between the battery and tool.

 

The run time of any battery will impact on its overall life span, the greater the run time the longer the battery will work effectively between charges.

Another advantage of Lithium-ion technology is that there is no power fade when the battery is coming towards the end of its charge.

 

Lithium-ion batteries have greater life spans than their Ni-MH or Ni-Cad counterparts this is due to the increased number of charging cycles Lithium-ion offers and the run time between charges.

 

For example the Makita Ni-Cad 18v 2.0Ah battery has 700 cycle life span The Llithium-ion 18v 3.0Ah battery has an even greater life span. We can see with the equation below that the Lithium-ion battery will effectively have over 4.3 times more working life than the Ni-Cad battery. This can be directly related to a cost saving, for every Lithium-ion battery purchased the user would have to purchase over 4 Ni-Cad batteries. Although the initial cost of Lithium-ion batteries is greater, in the long term Lithium-ion financially makes sense.
 

Makita have tested the Lithium-ion 18v 3.0Ah battery extensively under load. 50mm tapping screws were screwed into standard pine, replicating actual use conditions.
