Hyper Tough 20V Max 4.0Ah Battery Pack, HT21-401-003-11

• Lithium-Ion Batteries have a high energy density which provides a longer discharge time and provides consistent power through the charged cycle.
• Unlike NI-Cad batteries which slow down as energy is depleted, these Lithium-Ion batteries run full strength until all energy is expended.
• Once charged Lithium-Ion batteries also have a longer shelf life and will not lose power when not in use.
• This battery is sold as a single battery and does not include a charger or a tool.
