Yes or maybe not.
Search for battery charging to get a week of reading.
Bulk mode b is high inrush current on a less than charged battery.
Absorbion is current on a near charged battery.
Float is current on a fully charged battery.
Anytime current is flowing in a battery magic is happening and chemicals are changing.
If currents exceed certian points then excess gas is created and the source of this gas is the fluid in the battery.
Charge current at float should not exceed 0.1% C so if you had a 100 AH battery the float current should be about 0.1 amps and float voltage 13.5 to 13.6.
No charger should be trusted.
All should be placed on probation until they have proven worthy.
Simply put...monitor the voltage and water levels at a regular scheduled day to insure all is well.
Over time you may determine your charger can be trusted and batteries checked monthly or that it is over charging and needs something else.
Bottom line is you need to verify what you have and how it is designed to work then determine how you will operate it to meet your needs and not cause harm to the batteries.
