The weight of the battery was important for my comfort during use. I preferred a lighter battery that wouldn’t cause fatigue during extended projects. Portability mattered since I frequently moved my tools around, so I aimed for a battery that was easy to handle.

Price Considerations

I needed to establish a budget. I found that prices for 18V Li-Ion batteries can vary widely based on brand, capacity, and features. I compared options within my budget, ensuring I balanced cost with quality and performance.
