- Nickel Metal Hydride batteries (NiMH) :- this is another popular battery used by the common cordless drills. It is abbreviated as NiMH having a similar chemical reaction with Nickel-cadmium cell i.e. both use nickel oxide hydroxide.it is a good battery that can be used with cordless drills.

Recently, top brands are developing a new idea called ‘bare too’ product and according to manufacturers the new idea will improve on the previous machines because it’s a new upgrade to the machines made before.
While buying the battery, there is a buying method called ‘buying style’ which means when you buy the charger and the battery, you can buy the tool at a very cheap price, but if you are buying it as a bare tool only, it will be sold at a more expensive price.The disadvantage of this is that a particular brand of battery can’t be used for tools that don’t belong to its brand.

Properties of Cordless Batteries
Before buying a cordless battery, it is almost necessary to know the properties of the cordless battery because it will help while choosing the cordless battery of your choice.
The main features of cordless batteries include:
- Its life cycle: when talking about the life cycle of a cordless battery, it means the time at which the battery can power the drill. Some batteries can power a drill for a long time while some batteries can’t power drills for long so it’s the best decision to choose the battery which powers the drill for a longer
- Discharge rate: When talking about the discharge rate of a cordless battery, it simply means the rate at which the battery gets consumed while it is in use by the drill. There are some batteries that get drained faster while in use by the drill while some batteries don’t get drained faster so it is the best decision to buy a battery will not get drained so fast.
- Voltage sizes: When talking voltage sizes of a battery, it simply means the minimum rate of the voltage at which the battery will charge and the maximum voltage it can charge. For example, if a battery can charge at 180V-220V when charged with volts less than 180 volts, it will not charge and when charged with volts above 220 volts, it may stop charging or even get destroyed.
- Memory effect: When talking about memory effect of batteries, it simply means that while charging a battery and using it, with time, the battery remembers the point at which it’s charged to and the point it’s discharged to and soon it will stop to charge at that point and the power of the battery depreciates until it stops working. So it is important to know this before buying a battery because this does not apply to Lithium-ion batteries but applies to the other types of battery.
