Haier M2000 Battery and Longevity

Battery and Longevity

Energy efficiency was reasonable for its time, with two battery options: a removable Li-Ion 600 mAh battery, or an extended 800 mAh battery. These allowed up to 300 hours of standby and talk times of up to 4 or nearly 7 hours depending on the battery. The removable nature of the battery was a distinct benefit, allowing users to carry a spare for extended use.
