Lithium battery charge and discharge only 400-600 times, specifically changed products, but 800 times. The nickel-metal hydride rechargeable battery can get to a lot more than seven hundred times, some superior high quality products as many as 1200 times charge and discharge, this sort of a comparison, the nickel-metal hydride batteries live longer than lithium batteries. Moreover, the value of nickel-metal hydride batteries is far lower compared to the lithium batteries. Furthermore, strictly talking, lithium batteries hold the same memory outcome, but its memory outcome may be very low, in essence negligible.
