Lithium battery charge and discharge only 400-600 situations, specifically altered items, but 800 situations. The nickel-metal hydride rechargeable battery can reach far more than seven hundred situations, some good top quality items about 1200 situations charge and discharge, these kinds of a comparison, the nickel-metal hydride batteries live longer than lithium batteries. Additionally, the worth of nickel-metal hydride batteries is much reduced compared to lithium batteries. Moreover, strictly speaking, lithium batteries have the same memory impact, but its memory impact may be very reduced, basically negligible.
