When choosing an angle grinder, among the very first decisions to make is which type of battery to utilize. Below are the 2 main types:
Battery TypeProsConsLithium-Ion (Li-ion)- Lightweight
- Long life-span
- Quick charging- More expensive
- Sensitive to extreme temperature levelsNickel-Cadmium (NiCad)- Cost-effective
- Robust efficiency- Heavier
- Memory impact decreases life expectancy
Lithium-Ion Batteries are the preferred choice in modern-day power tools. They offer a higher energy density, which implies they can keep more energy in a smaller sized and lighter bundle, optimizing the tool’s portability and performance.

Nickel-Cadmium Batteries, while less typical today, can offer trusted efficiency, particularly in rugged conditions, however they include downsides including a heavier weight and concerns related to “memory effect.”
2. Secret Specifications to Consider
When choosing a battery for an angle grinder, numerous specs should be thought about to guarantee ideal efficiency:
