Makita has launched an innovative new battery for its 40VMax XGT range of high-performance tools. The 4.0Ah BL4040F battery is the first Makita battery to include cutting-edge tabless technology, which allows more efficient power delivery, better runtimes, and cooler running. As the latest Makita F-Type battery, it is engineered for the very highest-demand applications.
The tabless lithium-ion cells in the new BL4040F eliminate the bottleneck caused by current concentration by connecting the entire end of the electrode to the end of the cell, instead of connecting to tabs at each end.
With a larger connection area inside the cell, heat generation is minimised. This means that even under high load, the cell temperature is reduced compared to standard designs, which has a positive effect on the overall service life of the battery. A further benefit is that the battery can be charged immediately after intense use, with no need for a cooling phase, meaning shorter overall charging times. The tabless 4.0Ah BL4040F battery delivers up to 36% longer runtimes and operates 32% cooler compared to the standard 4.0Ah BL4040.
Like all Makita F-Type batteries, the BL4040F is a high-output battery designed for enhanced performance and better runtimes on higher drain tools such as chainsaws, breakers and demolition hammers. The new 4.0Ah BL4040F delivers the same 2.1kw maximum output as the 5.0Ah BL4050F. This means customers now have the choice of the larger, higher capacity 5.0Ah battery or the smaller, lighter 4.0Ah battery to achieve the high output that demanding tasks require.
