Safety features and protections
- Built‑in Smart Battery Management System (BMS) with 20+ safety features
- Low‑temperature cut‑off (charge protection)
- Over‑charge and over‑discharge protection
- Over‑current and short‑circuit protection
- High and low temperature disconnects
Installation and maintenance
To properly charge, ensure charging components can be programmed for Bulk/Absorption at 14.2–14.6V, with Float at 13.4–13.8V and Equalization at 14.4V (disabled). Absorption time for two batteries in parallel is approximately 30 minutes. Recommended charge rate is 50% of bank capacity. Battery is maintenance‑free; however, verify compatibility with your charger/controller (converters, inverter chargers, solar controllers, DC‑DC chargers) and follow their manuals for multistage charging capabilities.
Warranty and service
6 Year Manufacturer Warranty. The Epoch Eco Series is designed for long‑term reliability with a maintenance‑free profile and robust protection features to minimize downtime.

Recommended Charge 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)
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.
