Not suitable for Lithium. Load too quickly (in minutes, while it takes a cycle of about 3 hours to fully charge. As a result, the batteries are charged and just do not take. In addition, they heat! I went through the discharge-recharge cycles: nothing works. Very random result; some batteries are "full" 50 mA, other 150 mA, 250 mA others, etc ... Current load set to 0,50A (first tried to 1A) Some people have the same problems, where is the charger that is defective, where 6 CR123A 1200mAh GTL I took the same time?
