All batteries are voltage and IR tested before sale, and usually test at 90% state of health or above on average. Unless specified in the product or requested, full capacity tests on indivdual cells are not always done, samples from each batch are capacity tested before being stocked. It is expected that customers will capacity test cells on arrival for their own assurance. This allows the cost to remain very low. If your cells dont perform as expected, just let us know and we'll happily arrange a free replacement.
