Zapp Star discharge curves

Each curve above show the total amount of power drawn at a constant amount of power (amps). For all batteries, the higher the power (amps) drawn, the sooner the battery is discharged--to 9 volts, in the case above. Also true for all batteries, the higher higher-demand (higher power) test will always product LESS total energy drawn (in Watt-hours).

Why show discharge curves?

  • These are the actual test results for the first row under the "Watts: 58-hour output" in the pricing table. All other 58-hour cells in the pricing table are a multiple of these test results.
  • You can count on consistent performance, as documented, charge after charge.
  • Unlike other battery types, fully discharging is a realistic scenario, so it helps you understand how our batteries will perform.
