Battery Runtime Calculator
Estimate runtime using your battery capacity, pump selection, and timer sequence.
Sequence Instructions & Examples
Enter alternating ON and OFF times in seconds, separated by commas. The first number is ON, the second is OFF, and the pattern continues in that order. One complete sequence must end with an OFF time before the timer repeats.

Sequence Summary
Runtime is an estimate based on the entered battery capacity, manufacturer-listed pump draw, and selected timer sequence. Actual runtime will vary based on actual battery capacity, temperature, pump performance, and operating conditions.
