What is the true technical difference between a '20V Max' battery and an '18V' nominal battery pack?

Next

 Correct IncorrectThey use identical 5-cell lithium arrangements. 20V Max is the maximum initial voltage with no load, while 18V is the nominal voltage during normal use.

What is the true technical difference between a '20V Max' battery and an '18V' nominal battery pack?

• 20V Max uses alkaline chemistry instead of lithium-ion
• They are electrically equivalent: 20V is peak open-circuit voltage, while 18V is nominal working voltage
• 18V batteries cannot be recharged more than ten times
• 20V Max contains six cells instead of five
