Today's ultra-lightweight cell phones owe a debt of gratitude to Lithium Ion (Li-Ion) batteries which help to greatly lighten their loads. The latest and lightest in battery technology, Li-Ion batteries provide superior talk and standby times, but weigh up to 30% less than comparable Nickel Metal Hydride batteries. Li-Ion batteries can also be recharged at any time without suffering memory effect, a condition that can sap a battery's performance over time. |
