• Part of the SV12 Series offering a one battery fits all solution, keeping costs down without compromising on performance.• Lithium-ion batteries give an all-round better performance than standard Ni-Cd/Ni-MH cells.• Maintains a higher energy density level (generally twice that of a Ni-Cd cell) giving more battery power per gram.• Has a flat discharge curve - performing better for longer.• No memory effect - these batteries can recover from a deep discharge with no tendency to reduce overall capacity.• Charging Time: 140mins.• Suitable for use with the SV12 Series.• Weight: 0.18kg.Lithium-ion batteries give an all-round better performance than standard Ni-Cd/Ni-MH cells. Maintains a higher energy density level (generally twice that of a Ni-Cd cell) giving more battery power per gram. Has a flat discharge curve - performing better for longer. No memory effect - these batteries can recover from a deep discharge with no tendency to reduce overall capacity. Suitable for use with the SV12
