This means they can deliver more power with less energy lost as heat. The High Output 4.0Ah battery provides a 35% increase in power versus the standard 4.0Ah battery. ; Increased performance under load - As the lower internal resistance reduces the amount of heat generated during high-load operations, High Output batteries run cooler. This, in turn, allows the battery to run longer and continue to perform in high-demand continuous applications. ; Cooling system - effectively dissipates heat, safeguarding each cell and optimizing battery longevity. ; Optimum charging system - Optimum charging is achieved by feeding real-time data from the battery to the charging control system. Data such as battery condition and cell temperature are communicated to optimize the charge. ; Water and dust resistance - Water and dust-resistant triple-layer structure and an enhanced terminal structure are engineered to protect against water and dust for any job site condition. ; High rigidity battery rails - durable slide-in battery rails have been increased in size versus 18V LXT in order for the battery and tools to hold more firmly with high-powered XGT products. ; Shock absorbing structure - space is created between the heavy-duty outer casing and the cell holder to absorb impact should the battery accidentally be dropped. ; Specifications: Voltage 40 V Platform XGT Capacity 4.0 Ah High Output Energy Capacity 144 Wh Weight 0.94 kg Charge Time 45 minutes
