High output delivers more amps while staying cool. Also, the 12 ah battery is made up of 21700 cells, not 18650s.
Can someone please tell me what the difference is between the Milwaukie high output vs High Demand batteries?
Should get you started -
The M18™ REDLITHIUM™ HIGH DEMAND™ 9.0 Battery Pack delivers up to 5X more run-time, 35% more power, and runs 60% cooler than standard 18V lithium-ion batteries.
The M18™ REDLITHIUM™ HIGH OUTPUT™ HD12.0 Battery Pack provides 50% more power and runs 50% cooler vs M18™ REDLITHIUM™ HD battery packs.
