Powerhouse PH-Battery-1.3AH 20V 1.3Ah Lithium-Ion Battery

FEATURES:
High energy density – potential for yet higher capacities.
Does not need prolonged priming when new. One regular charge is all that’s needed.
Relatively low self-discharge – self-discharge is less than half that of nickel-based batteries.
Low Maintenance – no periodic discharge is needed; there is no memory.
Specialty cells can provide very high current to applications such as power tools
