When the battery for my wonderful Samsung 8500 phone started dying after quite some time of use, it was time to buy a new one. Having priced it at the sprintpcs store, I decided to look online for a better price. Whereas the sprint store had a pricing somewhere around $55 or so, I found a great price at batteries4less.com (also known as Cellphone Battery Warehouse), for $29.95. Even though I had to pay shipping of $4.95, it was still considerably cheaper, so I went for it. When it finally arrived, and after charging it the first night, it refused to hold the charge for more than half a day. I called the company, they told me to charge it three nights in succession, letting the battery get down very low before recharging, to "condition" the phone. I thought that's what you only had to do for the older type of cellphone batteries, but decided to try it, anyway, hoping they knew what they were talking about. Well, it still didn't work and then I discovered that I had bought what they call an "aftermarket" or "other supplier" battery. In other words, this was not made by Samsung. Today, after much frustration, I decided to return the battery and then was told by their rep that while they were happy to refund my money for the phone itself, I would have to eat the shipping charge of $4.95 - plus, of course, the shipping charge of returning it! They refused to budge on that issue. Had I known ahead of time that this was not an original Samsung battery, I never would have bought it. I guess the old adage is true, "you get what you pay for." Stay away from this company! Despite their claims to the contrary, the only thing you're getting is a guaranteed low price---and absolutely nothing else.
