I also pay attention to whether the battery is genuine, since I want reliable performance and better safety.
Battery Type and Compatibility
In my experience, compatibility is the most important thing. A 5 Ah Dewalt battery usually works well with 20V MAX tools, but I still double-check the model number before buying. I make sure the battery matches the tool platform I already own, because the wrong battery can waste money and create frustration.
Runtime vs. Weight
One reason I like a 5 Ah battery is the balance it gives me. Smaller batteries are lighter, but they do not last as long. Larger batteries run longer, but they can feel heavy during long use. For me, the 5 Ah option is often the sweet spot because I get dependable runtime without adding too much weight to the tool.
Charging Time
I always consider how long the battery takes to charge. A 5 Ah battery usually needs more time than smaller batteries, so I like to pair it with a fast charger if possible. That way, I can reduce downtime and keep working without long interruptions.
