When picking an angle grinder, one of the very first choices to make is which kind of battery to utilize. Below are the 2 primary types:
Battery TypeProsConsLithium-Ion (Li-ion)- Lightweight
- Long life-span
- Quick charging- More costly
- Sensitive to severe temperature levelsNickel-Cadmium (NiCad)- Cost-effective
- Robust performance- Heavier
- Memory effect lowers lifespan
Lithium-Ion Batteries are the favored choice in contemporary power tools. They offer a greater energy density, which implies they can store more energy in a smaller and lighter package, enhancing the tool’s portability and performance.

Nickel-Cadmium Batteries, while less typical today, can provide trustworthy efficiency, particularly in rugged conditions, but they come with downsides including a heavier weight and concerns connected to “memory effect.“
