RECOMMENDED CHARGING SETTINGS:
To properly charge your Epoch Batteries, you will want to verify that any charging component in your system is capable of being programmed for the following specifications. Charging components can include, but are not limited to converters, inverter chargers, solar charge controllers, DC to DC chargers, etc.
- Bulk/Absorption: 14.2V – 14.6V
- Absorption Time: Two batteries in parallel connections require 30 minutes 200Ah
- Float: 13.4V – 13.8V
- Equalization: 14.4V/ Disabled
- Temperature Compensation: 0/Disabled
- Charge Rate: 50% of the battery or battery bank capacity
- Battery Charge Temperature Range: 32°F (0°C) to 131°F (55°C)
- Battery Discharge Temperature Range: -4°F (-20°C) to 140°F (60°C)
- Cell Charge Temperature: 32°F (0°C) to 131°F (55°C)
- Cell Discharge Temperature: -4°F (-20°C) to 140°F (60°C)
NOTE: Not all chargers are capable of multistage charging. If yours is not, you will want to verify it can be programmed for the Bulk/Absorption voltage and have the other items mentioned disabled if applicable. Consult your charger's manual or the manufacturer.
