Capacity – batteries with different technologies

So what do you need to remember when selecting battery types for different applications? Here are a few important parameters:

  • Energy density – i.e. how much energy the battery cell actually contains
  • Available physical dimensions
  • How many charging cycles the battery can handle before it needs to be replaced
  • How long it takes to discharge the battery
  • How quickly the battery can be charged to full capacity
  • Degree of self-discharge

What is the capacity of lithium-ion batteries compared with traditional lead acid batteries? This diagram will tell you.
