Hello! I have a question regarding flooded lead acid cell charging. All of this talk of battery charging seems to be focused around charging small capacity sealed batts, so I want to be a little more sure about how to properly charge large capacity flooded lead acids. I want to use either the bq2031 or the UC3909 to charge some 6V 260 AH flooded lead acid cells (4 series connected batteries for 24V). The bq2031 can do pulsed current charging, whereas the UC3909 performs the multi-stage algorithm (bulk, overcharge, float). My questions are as follows:
1. Is pulsed current charging of large flooded lead acid batteries recommended or even used in industry?The bq2031 supports pulsed current charge which iis why I i am asking.
2. Since these batteries are flooded cells that can be re-hydrated with maintenance, how important is providing temperature compensation. Can I get away without temp compensation since these are large flooded industrial cells that I can add water to (provided I charge at a current less than 1/8 of the 20 hr rate).
3. What would be better for flooded cells: pulsed current charging or multistage charging algorithm?
Thank you so much for your time and I look forward to using your product(s).
