Makita BL4080H 40V XGT 8.0Ah

The BL4080H is the most powerful 40V max XGT battery in the Makita lineup, built for tools that place heavy demands on their power source: chainsaws, grinders, rotary hammers, and other machines run continuously on site. Its 8.0Ah (288Wh) capacity matches the standard BL4080F, but the internal technology changes everything: so-called "Tabless" cells, which remove the traditional connecting tabs between electrodes to let current flow more freely.

The result Makita claims: up to 35% more continuous power than the BL4080F, and operation up to 32% cooler under sustained heavy load. On power-hungry tools (chainsaws, blowers, large-diameter grinders), that thermal headroom translates into power that holds up better over time, without the drop-off caused by overheat protection kicking in.

A full charge takes 76 minutes or less with a DC40RA or DC40RB rapid charger. A 4-LED charge indicator, activated with a simple press, lets you check the charge level without clipping the battery onto a tool. Digital communication between the battery and the machine continuously optimizes power delivery, and a protection system constantly monitors the risk of overload, over-discharge, and overheating.

On the durability side, the reinforced casing and rigid rails keep the battery firmly secured to the tool even under heavy use, and water and impact resistance have been improved compared to earlier XGT batteries. At 1.8kg on the scale, it's even slightly lighter than the BL4080F (1.9kg), despite its higher power output.

This battery remains compatible with the entire 40V max XGT system, including the most demanding dual-battery tools. It's aimed mainly at professionals and heavy users who already own XGT tools and want to push the power and runtime limits of their system further, rather than at a first XGT purchase: the cheaper standard BL4080F is more than enough for everyday use.
