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.
