How high can a 1 kilogram battery lift itself???

Below is a graph that shows an analysis of how high different types of batteries could lift themselves based on a 1 kilogram basis of weight of the battery. The y-axis displays the height the battery can lift itself in kilometers.

These heights were determined using the energy densities that were found in the following table:

Type Voltage Energy density Energy density Power Internal Resistance Efficiency Energy/$ Discharge Cycles Life (V) (Wh/kg) (Wh/L) (W/kg) (Milliohms) (%) (Wh/$) (%/mo) (#) (years) Lead Acid 1.8 - 2.1 30-40 60-75 180 50 70%-92% 5-8 3%-4% 500-1500 5-20 Nickel Cadmium 1.0 - 1.35 40-60 50-150 150 75 70%-90% 5%-20% 500-5000 5-10 Nickel Metal Hydride 1.2 - 1.4 30-80 140-300 250-1000 75-650(1000 charges) 66% 1.37 25%-30% 800-1200 5-10 Lithium Ion 2.0 - 3.6 150-280 250-450 1800 320 90+% 2.8-5 5%-10% 570-1200 2-3
