The battery life of a cordless jigsaw depends on several factors, including the battery's capacity (measured in ampere-hours, Ah), the type of material being cut, the thickness of the material, the speed settings used, and the efficiency of the jigsaw itself.
Typically, cordless jigsaws use lithium-ion batteries, which are available in various capacities, commonly ranging from 1.5Ah to 5.0Ah or more. A higher Ah rating generally means longer battery life. For example, a 2.0Ah battery might last around 20 to 30 minutes of continuous use, while a 5.0Ah battery could last up to 60 minutes or more under similar conditions.
The type and thickness of the material being cut significantly affect battery life. Cutting through dense or thick materials like hardwood or metal requires more power, thus draining the battery faster compared to cutting softer materials like plywood or plastic.
The speed setting on the jigsaw also plays a role. Higher speed settings consume more power, reducing battery life, while lower speeds can extend it. Additionally, the efficiency of the jigsaw's motor and the sharpness of the blade can impact how quickly the battery depletes.
In practical terms, for light to moderate tasks, a fully charged battery might last for several hours of intermittent use, allowing for breaks between cuts. For heavy-duty tasks, the battery may need recharging or swapping more frequently.
To maximize battery life, users can keep spare batteries on hand, use the appropriate blade for the material, and operate the jigsaw at optimal speed settings.
