How long will a battery powering a repeater last?
It depends on the battery and the amount of data the repeater transmits. If you are using a good quality, fully charged, deep cycle marine battery, you can expect at least 45 days. The software will inform you when the repeater is not working. However, it’s best that you have a small, digital multimeter (about $20 at Radio Shack) at your disposal to test the battery each week so you will know in advance when the charge is getting low.
