BATTERY CAPACITY (Gives you more charge, less weight)
In short, battery capacity refers to how much charge is in the battery (how long the current that is drawn from the battery can continue while the battery can supply a load). Let’s compare the capacity and size of lead acid, nickel metal hydride and Li-ion batteries:
If all three are the same CAPACITY (producing the same charge):
The weight of Lead - NiMH - Li-ion will be around 6:3:1
(Meaning: Li-ion is considerably lighter)
If all three are the same SIZE:
The capacity of Lead - NiMH - Li-ion, will be around 1:2:4 respectively
(Meaning: Li-ion can produce far more charge)
In summary: Lithium is far lighter and produces more charge than its counterparts.
Example: Say you had two machines that had the same size battery pack. If you use a Li-ion battery pack, you’ll get eight hours of running time and the device will be lighter. With a lead acid battery pack you’ll only have two hours of running time and the machine will be much heavier.
EFFICIENCY (Get more out of your battery)
Lithium batteries are more efficient than other battery types. For example, most lead batteries are only 80-85% efficient, depending on the condition and model. Alternatively, lithium batteries are more than 95% efficient. This means you’ll keep your batteries for longer.
CYCLE LIFE (You can charge your battery many more times)
Battery cycle life is the amount of time you can charge and discharge your battery before it gives up and needs to be replaced.
Lead acid battery: approximately 300 to 400 cycles
Lithium-ion battery: approximately 500 to 600 cycles (With the improved technology of the Torphan Li-ion batteries however, you still have 50% capacity after 1400 cycles)
ENERGY DENSITY (More energy in less space)
Lithium batteries can fit much more energy into less space than lead batteries. Consequently, they take up less space in your device, allowing for lighter, better design and improved manoeuvrability.
