I increased the alarm setting to 13.4 and it has stopped the alarm, however the charger is for lead acid flooded batteries and the recommended voltage is 13.2V on the website. Not sure if the Multiplus is over achieving….

What batteries do you have?
Most lead and also lithium batteries need 14.2 to 14.6V absorption voltage.

So a high voltage alarm should be set to maybe 15V
