Appendix B: Battery Life

While battery life depends on several factors such as charge, condition and temperature; it

can generally be assumed that the sampler can deployed in the field for more than 3

months waiting to be triggered, while still retaining enough charge to run a single pump for

one hour (about 10 gallons) or both pumps for ½ hour (5 gallons). To prevent large current

surges which occur when the pumps first turn on, the WS750 is designed so that only one

pump will turn on or off at a time. A ½ second time delay is inserted between these events,

extending the life of the charge and the life of the battery.
