What's mean High Self-discharge(1)?

What's mean High Self-discharge(1)? Self-discharge is a natural phenomenon of any battery. It is not a manufacturing defect per se, although poor manufacturing practices and improper maintenance and storage by the consumer enhance the problem. The level of self-discharge differs with each chemistry and cell design. High-performance nickel-based batteries with enhanced electrode surface area and super conductive electrolyte are subject to higher self-discharge than the standard version cell with lower energy densities. Self-discharge is non linear and is highest right after charge when the battery holds full capacity. NiCd and NiMH battery chem View the rest of this article
