How long will the battery last in my battery operated or solar fence controller?
For battery operated fence controllers Zareba Systems suggests using a marine deep cycle battery rated for at least 85 amp hours. In normal operation, the battery could be expected to last several weeks before having to recharge. For solar operated fence controllers, the internal battery should last 3 to 4 years. This is dependant on how the controller is installed and or stored. If the controller is out of sunlight for 3 months or more, the battery starts to lose voltage. A battery that loses over 3 volts without being recharged may not take a charge or even hold the charge thus limiting its life cycle.
