he new 36volt Lithium Ion range from DeWalt
is said to offer mains power performance from abattery tool.Although it is by no means the firstmanufacturer to offer this technology, DeWalt
says that it held back from introducing Li-Ion becauseit has been working on a variation that overcomessome of the early problems of Lithium Ion. It neededto produce a battery that copes with the heatgenerated by the high level drawn by power tools andhas come up with a battery unlike any of the typesalready on the market.

Li-Ion has no memory,which means you can top it upbefore it is depleted.
