Query: the batteries are out of power too soon

6 out 10 batteries in the pack were used and all of them started to show weak power in just a few minutes. They are only to be used to power up some LEDs which don't consume much power. The previous batteries lasted for years. But these 6 batteries were completely out in less than a week under the same usage pattern. It was a very cheap buy but still it was a waste. It could be that they are long expired.
