Panasonic EY9L54B 18V 5Ah Battery

This is the Panasonic EY9L54B 18V 5.0Ah Lithium-ion battery for 18 volt Panasonic cordless tools.

  • Capacity: 5.0Ah

Compatible with

  • ALL Panasonic 18V tools
    (including dual-voltage and triple-voltage)

  • Excellent power to weight ratio: no increase in size from the Panasonic 18V 4.2Ah Li-ion battery
  • 250% longer lifetime than Panasonic’s older Lithium-ion batteries
  • Individual monitoring of battery cell voltage: each 3.6V segment is monitored by a sensor to ensure optimal discharge control, preventing overcharging and overdischarge
  • Battery Overheat Protection Sensor (OPS): a temperature sensor cuts-off power to the motor before the battery’s temperature reaches a harmful level and alerts the user via a flashing light on the tool’s control panel
  • Heat Resistance Layer (HRL) technology: a special coating separates the battery cells and protects against overheating
  • Li-ion technology: no memory effect, no lazy battery effect, excellent power-to-weight ratio, virtually no self-discharge, and the ability to withstand colder temperatures in working order
