The care and feeding of batteries
  1. Chemistry of Batteries
  2. Energy Capacity of Batteries
  3. Internal Resistance
  4. Proper Discharging
  5. Recharging
  6. Reincarnation

Procedure

  1. Determine the type of Battery and list its chemistry
  2. Describe how you could non-destructively measure the energy capacity. Describe the voltage vs. time curve of a battery.
  3. Use Thevenin's theorem to find the internal resistance
  4. Recharge you battery for a few minutes and recalculate the internal resistance. Discuss the 3 methods of recharging a battery and the limitations of each method. Use the best method to recharge the battery!
  5. Can dead batteries be revived? Explain what makes them die.
