FDK (formerly Sanyo) Twicell (formerly Eneloop) 9.6V, 1900mAh, AA 8 Cell Square Pack.FDK's more environmentally friendly NiMH battery.
Although these are advertised as charged and ready to go right out of the package, we recommend a forming charge period prior to use. Our tests have shown them be factory charged to 60% or less. Twicell NiMH cells have a lower daily self discharge than typical NiMH cells.
Break in (first forming charge) for 1900mah pack on 50mah charger - 54 hours, 70mah charger - 40 hours. Individual Cell Internal Impedance 96.0Ω
Although Sanyo's website shows Cx1 (capacity x 1) fast charge rates with a NiMH rated charger, I'm not prepared to warranty any packs damaged by fast charging or peak charging in any form. If you insist on experimenting with fast charging and damage a pack, call Sanyo, not Radical RC.
