Li-Ion has quickly become the standard for portable power in consumer devices. Li-Ion batteries produce the same energy as NiMH batteries but weigh approximately 35% less. Li-Ion batteries do not suffer from the memory effect AT ALL. They are also better for the environment. What does the mAh mean and how does it relate to how long my battery will last? mAh stands for "Milliamp Hour" and it is the unit used to measure battery capacity. The higher the mAh rating of a battery, the longer it will operate at the device"s power consumption rate before needing to be recharged. Should I Recycle My Old Battery? How? NiCad, NiMH and Li-Ion batteries should be recycled. Be environmentally conscious - do NOT throw these batteries in the trash.
