Here is a question What make/model converter do you have. a 2003 good chance you have a 3-stage converter/battery charger/ maintainer.. This type of converter has a "Bulk" mode where it puts it major amps to charge the battery. then an Aborsption mode. low current but generally higher voltage to finish charging the battery.. then it switches to "Float" mode where it can sit dang near forever without damage to the battery.
Back in the last century they had single stage converters (Still do but they are better regulated now days) that had poor regulation and they would seriously overcharge your batteries and kill them.. But that's.. as they say..
"So Last Century" Today the single stages (usually the float voltage) or dual (Bulk/Float) or 3-stage. Some are 3-stage + (Progressive Dynamics Wizard models nd IOTA IQ-4 models) They don't get better than that.
It's a Parallax Power Components Model 7455 - Converter/Charger. Manual says it puts out 14V when power is first applied, and then after 12 hours it drops down to 13.2V. That's about all I know about it.
