What is the difference between the battery packs?

The difference between battery packs is run time. They all weigh the same (about 2.8 lbs.). The B600E 4.0 Ah Battery Pack offers 50% longer run time than the B425E 2.6 Ah Battery Pack. The B650E 6.0 Ah Battery Pack offers 50% longer run time than the B600E and 130% longer run time than the B425E.

What is the difference between lithium ion batteries and others?

Batteries with lithium ion chemistry have four advantages over other power tool batteries:
  • High power density – lithium ion battery cells have both high power and light weight
  • No fade – lithium ion batteries deliver constant power throughout the pack discharge
  • No memory effect – charge maintenance and full discharge are not necessary to retain consistent capacity throughout battery pack lifetime
  • PowerNow Lithium Ion Batteries stay charged for months when left off the charger

How should I store my battery?

It is best to store the battery in a cool, dry location. It is perfectly safe to leave the battery on the charger to ensure your battery is always 100% charged and ready for work.
