Its Flaws

    While the bulk of customers who have purchased these batteries report being very happy with their performance and capacity, there are others who were not as satisfied. Some customers reported that they have some concerns that the EBL 3000mAh 3.7V 18650 Li-ion Rechargeable Batteries might not actually hold all of the advertised 3000mAh. These individuals noted that their charging devices only recorded a capacity of somewhere around 2100 to 2400mAh on these batteries — and some consumers reported even lower amounts than this.
    This is more of a general notice when purchasing batteries: be sure that you check carefully to see what is included in your purchase. It is common for batteries and charging units to be sold together, but this is not always the case. Some purchasers of this product were under the mistaken impression that they would be receiving a charger or a battery case with their purchase of batteries. To be fair, the manufacturer is clear about what is included, and the buyer simply needs to carefully review the stated product guidelines. Sometimes, reviewers will confuse the issue and talk about charging units or battery cases in their reviews, even if the product on sale doesn’t include those features. When comparison shopping, a good rule of thumb is to rely on what the manufacturer advertises in the actual listing as opposed what is mentioned in reviews.
