Lithium battery charge and discharge only 400-600 periods, specifically changed products and solutions, but 800 periods. The nickel-metal hydride rechargeable battery can attain more than seven-hundred periods, some superior superior products and solutions approximately 1200 periods charge and discharge, these types of a comparison, the nickel-metal hydride batteries reside for a longer period than lithium batteries. Additionally, the value of nickel-metal hydride batteries is far reduce compared to the lithium batteries. Furthermore, strictly speaking, lithium batteries have the very same memory result, but its memory result is incredibly decreased, fundamentally negligible.
