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.

Energy storage
With two 120ah with cold cranking in perilell, Three days of trolling motor and still Starts my big outboard every time.
Too Early to Tell
Installed them but won’t use for a month or two so I can’t review performance yet.
Great battery
final piece to my lithium transfer
