SLA Batteries
Rechargeable sealed lead-acid batteries
- Operation: -20 to +60 degrees
- Typical battery life: 5 years
12 volt, 7.2 amp-hour
This battery is recommended for the OWL when 12 volts is required by external equipment such as the Irrometer, tensiometer, or Anabat. The OWL itself can operate on either 6 or 12 volts.
- 6 x 2.5 x 4 inches
- 5.4 lbs
- connections via 3/16 inch fast-on tabs, spaced 2 inches apart.
- charging at 25 degrees Celsius:
- float charge at 13.8 volts at 20 degrees Celsius. Temperature compensate (-0.025 volts per deg. C), i.e. 13.3 volts at 40 deg. C, 14.3 volts at 0 deg. C.
- cycle fast charge at 14.6 volts, <0.5 amps. Temperature compensate (-0.025 volts per deg. C), i.e., 14.1 volts at 40 deg. C 15.1 volts at 0 deg. C. Switch to float when I<40 milliamps.
