 OEM converters are notoriously cheap and dumb (lacking [[electrical:12v:charging|smart charging]] functions).  Since they are stuck at one voltage the manufacturer picks a compromise setpoint.  If this is set too high or too low //for your usage patterns// it can damage lead-acid batteries ([[electrical:batterycide|batterycide]]). OEM converters are notoriously cheap and dumb (lacking [[electrical:12v:charging|smart charging]] functions).  Since they are stuck at one voltage the manufacturer picks a compromise setpoint.  If this is set too high or too low //for your usage patterns// it can damage lead-acid batteries ([[electrical:batterycide|batterycide]]).
  
-This compromise setpoint should coincide with standard float voltages for your battery bank.  Typically this would be 13.2v - 13.4v for converters that are always on the grid, and 13.8v for batteries that are cycled but get put back on grid charging regularly.+This compromise setpoint should coincide with standard float voltage (Vfloat) for your battery bank.  Typically this would be 13.2v - 13.4v for converters that are always on the grid, and 13.8v for batteries that are cycled but get put back on grid charging regularly.((Solar charging at a single setpoint, as with a [[electrical:solar:charge_controller&#shunt|shunt controller]], is done at [[electrical:solar:shunt_tweaking|Vabs rather than Vfloat]].))

-Aftermarket converters tend to be higher quality than OEM, but some are still "dumb" single-stage chargers.  Higher-end aftermarket converters often have multistage charging built in, or available as an upgrade.((See the PD w/Charge Wizard below))+Aftermarket converters tend to be higher quality than OEM, but some are still "dumb" single-stage chargers.  Higher-end aftermarket converters often have multistage charging built in, or available as an upgrade.((See the PD w/Charge Wizard below))  Note that a "dumb" charger might be fine if you have solar power on the vehicle, as the [[electrical:solar:charge_controller|solar charge controller]] is likely a "smart" charger.
