MAKITA DLX2012MWX 18V COMBI DRILL/ IMPACT DRIVER (TWIN PACK)

Ni-Cad (Nickel Cadmium) battery.
These batteries are reasonably priced but are very damaging to the environment. They also need to be completely discharged and cool to be able to accept a full charge.

Ni-MH (Nickel Metal Hydride) battery.
With this battery technology it was possible to increased the amperage to 3.0Ah, they are also a better option environmentally than Ni-Cad. They can be fully charged whether they are warm or partially discharged.

Li-ion or Lithium-ion batteries.
Lighter weight, quicker charging and with more run time than an equal voltage Ni-Cad or Ni-MH battery. These batteries have a chip that communicates with the charger for optimum charging. Lithium-ion batteries also offer much improved charge retention over long periods of storage. Li-ion batteries do not have to be fully discharged before charging in fact they can be charged at any time with no ill effect.

Vibration
Machines by their nature have the habit of transferring vibration to the user. Use AVT machines to reduce your exposure to vibration. Vibration above
2.5 m / s ² is harmful.

The maximum time of exposure depends on the vibration value:
5 m/s²: 8 hours
10 m/s²: 2 hours
20m/s²: ½ hours

Tri-axial vibration values are used to calculate all Makita vibration figures.
