Query: Useless

I purchased these batteries for use in a small, battery-operated candle - the kind that imitates a flame by flickering off and on. I don't think this is a particularly energy-intensive use. Batteries that I've bought for this purpose before have lasted for a couple weeks of continuous usage (more if I remember to turn the candle off). These batteries produced a feeble light, as though they were already nearly depleted when I began to use them, and lasted exactly 90 minutes before they stopped working entirely. I realize these were cheap and that you do get what you pay for, but it's also true that it's just plain illegal to sell an item that can't be used for the purpose for which it's advertised. These batteries are useless, and Amazon should cease dealing with the vendor who advertises them.
