I have a similar question to this original post, but with some more details to provide. My 100AH AGM battery is a Fusion CBC12V100AH and includes the following information printed on it regarding constant voltage charging:
Standby Use (Float Charge): 13.5~13.8 Volts @ 25C
Cyclic Use: 14.4~15.0 Volts @ 25C
Max Charging Current: 30A
Based on that information when the battery has been moderately discharged I would have thought that using Blue Smart IP65 Charger it would be appropriate to use "high" mode rather than "normal". What is the recommended mode for that information?
