I am looking to replace the battery on my CB350F and I would like to fit an AGM unit but I have had a bad experience with one in the past.
My Moto Guzzi California III managed to overheat an Odessy battery causing the plates to buckle, the acid to boil and the casing to split. I suspect that it was caused by poor regulation of the alternator output. The bike had a Saprisa permanent magnet alternator so the regulator was basically a Zener type and it seemed to produce 14v or more under almost all conditions.
I have fitted an Electrex World RR24 Rectifier/Regulator to the Honda so it should be a great deal more sophisticated.
Does anyone out there have any experience of AGM or Gel batteries with these modern solid state control units?
