When selecting an angle grinder, one of the first choices to make is which kind of battery to utilize. Below are the 2 primary types:
Battery TypeProsConsLithium-Ion (Li-ion)- Lightweight Angle Grinder
- Long life-span
- Quick charging- More costly
- Sensitive to extreme temperaturesNickel-Cadmium (NiCad)- Cost-effective
- Robust efficiency- Heavier
- Memory result decreases lifespan
Lithium-Ion Batteries are the favored choice in modern power tools. They offer a higher energy density, which implies they can save more energy in a smaller and lighter package, enhancing the tool's mobility and efficiency.

Nickel-Cadmium Batteries, while less common today, can provide trusted performance, especially in rugged conditions, but they feature drawbacks consisting of a heavier weight and problems related to "memory effect."
2. Secret Specifications to Consider
When choosing a battery for an angle grinder, several requirements need to be thought about to ensure optimum performance:
