Ryobi 18V 2.0Ah Compact Lithium+ Battery RB1820C
The Ryobi RB1820C 18V ONE+ 2.0Ah compact Lithium+ battery pack (product code 5133005052, EAN 4892210194633) is an ultra-lightweight power source engineered to provide maximum maneuverability, superior tool balance, and continuous power delivery across all cordless tools within the Ryobi 18V ONE+ ecosystem. Featuring intelligent IntelliCell™ battery management, it individually monitors and balances each cell to maximize usable power, operating runtime, and long-term durability. It incorporates an on-board 4-stage LED fuel gauge (100%, 75%, 50%, 25%) for clear remaining charge assessment. Its heavy-duty casing with integrated impact protection and featherlight weight of only 0.4 kg minimize fatigue during overhead and extended operations. Supplied individually in clear packaging.
Key Features and Construction Advantages
