What is the primary difference between primary and secondary cell batteries?

Primary-cell batteries can be recharged and used many times, whereas secondary-cell batteries cannot be properly recharged
None of these
Secondary-cell batteries can be recharged and used many times, whereas primary-cell batteries cannot be properly recharged
Primary-cell batteries use chemical cells, whereas secondary-cell batteries use an alternative energy source, such as thermal or magnetic energy, to supplement their outputs
Primary-cell batteries must be recharged at a much slower rate that secondary-cell batteries
