(0-45 c) t o avoid overcharge, a timer is used to terminate the charging after 150% capacity input. 2) normal charge 700ma x 2-3hrs. (1 h........................................................... 1.5 0.5 mm 0-45 c) t o avoid overcharge, a timer is used to terminate the charging after 150% capacity input. a joint use of dt or - v cut off is required. for dt contr ol, a maximum allowable temperature rise is 1 c/min. or if - v control is used, the maximum allowable voltage decrease is 10 mv/cell. in addition, a temperature cut off (tco) device, i.e. thermostat, with cut off temperature at 55 c must be used for safety purpose. 3) quick charge quick charge over rate 0.5ca is not recommended. storage: 1) storage t emperature........................-10 c to 45 c 2) remain trace of charged capacity for prolonged period of storage. 3) slow recharging of stor ed batteries for every 3 months. remark: weight and internal impedence ar e for reference only . 0.2c / 0.5c / 1c rate discharging curves 0.2c/0.5c rate charging curve 0.1c rate charging curves (with jacket) h d d h 2A140MC v o l t s 0 0 . 2 0 . 4 0 . 6 0 . 8 1 1 . 2 1 . 4 1 . 6 0 2 0 4 0 6 0 8 0 1 0 0 1 2 0 1 4 0 c a p a c i t y % 0 . 2 c 0 . 5 c v o l t s 0 0 . 2 0 . 4 0 . 6 0 . 8 1 1 . 2 1 . 4 1 . 6 0 2 0 4 0 6 0 8 0 1 0 0 1 2 0 1 4 0 1 6 0 c a p a c i t y % 0 . 1 c v o l t s 0 0 . 2 0 . 4 0 . 6 0 . 8 1 1 . 2 1 . 4 1 . 6 0 2 0 4 0 6 0 8 0 1 0 0 1 2 0 c a p a c i t y % 1c 0.5c 0.2c
