Battery Life Tips

  • Keep the pump fully charged and ready to use (you can't "overcharge" it) 
  • Battery indicator bars on the pump are not an exact measurement of time 
  • Battery will drop down quickly during the first 50% of a full charge, and then much slower on the last half
  • It takes a little bit longer to charge from 95% to 100%
  • Periodically deplete the battery through use to help maintain the overall life of the battery
