Load Banking 101 | How A Load Bank Test Works with a Generator
How often should load bank testing be performed? For non-mission critical generators, it is recommended to perform load bank testing at 80% of maximum load for 60 minutes at least once per year. Critical generators, such as those in healthcare or data centers, may require more frequent testing based on industry regulations and specific requirements.
What should battery voltage be reading under load?
Re: What should battery voltage be reading under load? More or less around 12.7 VDC is "resting voltage"... Battery below this voltage is discharging (if under load) or less than full charge (if resting). ~13.6 volts is "float charging" (keeping the battery full, but not really actively charging). Around 14.0 to 14.5 volts is actively charging.
