My Eneloop transmitter pack went bad in 11 months. I really tried to follow everything i was told. The battery company told me i had to hold the battery and if it got to hot to stop the charge. OK, who is going to stand there with a 2000ma pack and charge it slow and hold it in your hand all night to see if it gets hot. $50 bucks down the drain. I never charged it fast and used a peck detector charger at only 600ma. I was told I could charge from 120ma to 1amp. Dennis
