This may be unnecessary as I myself probably learned of this device right here but in case helpful, these little $22 Batt-O-Meters are wonderful. I just used my new one for the first time to learn instantly that the battery powering my Reverend Avenger's UGB was down to barely 7 volts. After replacing the battery, the new one tested at 9 and half volts. All in seconds!
