Lithium battery charge and discharge only 400-600 periods, specially altered items, but 800 periods. The nickel-metal hydride rechargeable battery can reach more than seven-hundred periods, some fantastic superior items as many as 1200 periods charge and discharge, these kinds of a comparison, the nickel-metal hydride batteries are living for a longer time than lithium batteries. On top of that, the value of nickel-metal hydride batteries is much reduced compared to lithium batteries. Additionally, strictly talking, lithium batteries have the exact memory effect, but its memory effect is rather low, essentially negligible.
