The Hitachi EBM1830 Li-Ion Battery weighs over 50% lighter than an average NiCd battery and lasts longer between charges than leading NiCd and NiMH technologies. There is no discernible loss of performance throughout the battery charge. The user should be aware that the machine may cut out when the battery needs recharging. This is not a battery fault; the new technology protects the battery cell, giving extended charging cycles when compared to previous battery technology.
For use with all Hitachi 18 Volt power tools, except with machines that use slide-on style batteries.
Battery Capacity: 3.0Ah.Battery Chemistry: Li-Ion.Voltage: 18 Volt.
