LXT: Makita Advanced Battery Technology

• 5x lower self-discharge keeps battery cells active and ready for use, even after long periods of storage.
• Charging at any time will have no effect on the battery--no memory effect, no conditioning, no life cycle lost.
• Built-in shock absorbing features protect the battery.
• Sixteen firm holding contact terminals reduce the risk of power loss/fluctuation in high vibration work environments.
• Battery's built-in Memory Chip communicates with the charger to maximize battery life using 3 Active Controls (Current, Voltage, & Thermal)
