Useless 40

When I got the product, I noticed that the battery had some minor exterior damage. But since you already do not see the built-in state, I did not care. The battery was finally installed and the iBackup program I learned that ultimately the battery had only 4 charging cycles behind. Thus, he was technically new. However, when I joined the iPhone to the charger, the battery will not charge read. I have now tried several times to charge the battery it, but without success. Can only advise to buy this product.
