  • •"Replace battery soon" warnings
  • •Battery age 2-3 years with heavy use
  • •Requires charging more than twice per week

Action: Order replacement proactively → View all batteries

Operational Issues

  • •Inconsistent runtime (varies by 30%+ between charges)
  • •Takes 50% longer to charge than when new
  • •Battery gauge shows inaccurate readings
  • •Pump occasionally switches to AC power unexpectedly

Action: Plan replacement during next maintenance cycle

Battery Still Serviceable
Signs your battery has remaining useful life
  • Runtime is 70%+ of original specification

  • No physical damage or swelling
  • Battery age under 2 years with normal use
  • Passes monthly diagnostic tests

Action: Continue monitoring, test monthly
