Summary of suits and radios: 1) Original battery from suit #3 was charged via separate charger to 11.5 volts, and after it was disconnected voltage dropped to 10.56 in about an hour. The battery was considered faulty, marked, and put away in the cabinet with EVA suits spare parts. 2) Inspection of EVA suit components did not reveal any faults in the power circuits. 3) Another used battery was placed into the suit, charged to 13.5v via a separate charger. Suit was turned on to test battery discharge. This battery dropped voltage from 13.5v to 5.09 just in 1h15min. After this we moved the battery into suit number 10 to do an additional charging test and a brand-new charged battery was placed into suit #3 to continue testing.
