The larger the tool’s battery capacity, the longer it will run before needing recharged.
Quite simply, if you are going to be relying on your cordless screwdriver to run for longer periods of time, then battery capacity is going to be an important factor in deciding which one is right for you.
For time consuming drilling or screwdriving tasks, select a model with a larger battery capacity, (2.5 Ah or higher) to ensure it runs for longer between charges.
Batteries with higher amp hour ratings are often used by workers in the construction industry, who don’t want their tools to be out of use during the workday.
For less time-consuming tasks, select a cordless screwdriver with a smaller battery capacity (less than 1.5 Ah), so you’re not paying for something you don’t need.
