Which battery should you choose for your power tools?

There are two criteria to look for when choosing a battery: the technology (old ones with NiCd, cadmium etc. and the new one with lithium) and the amperage (power, autonomy etc.). The battery is in a way the "tank" of the tool and the value indicated on it, expressed in ampere per hour, designates its "capacity". To simplify, on an 18V screwdriver, a 6 amp-hour battery will offer twice the autonomy of the same 18V battery in 3 amp-hour. However, this comparison is not valid between two batteries of different voltages (3 amp-hour in 18V and 4 amp-hour in 36V). In addition to providing additional autonomy, a battery with a higher amperage also provides more power to the tool.

Today's batteries are almost all lithium based. The most powerful batteries are the 18650 cells that make up, for example, Bosch's Procore range, Metabo's LIhd and all Milwaukee batteries (these are also the cells found in Tesla’s batteries). A Lithium-Ion battery is the most economical rechargeable battery in terms of cost to energy ratio. These batteries do not have a memory effect, unlike the older technologies (Nickel Cadmium...). On the other hand, they do not withstand a total discharge. So you should always make sure you recharge them in time.
