7. here is a fault Possible causes The battery is probably worn out and should be replaced Some large antimony batteries may behave differently and can allow the US 800 to charge the battery for too long which can lead to overcharging See caution If power consumers like fitted alarms and navigation computers are connected to the battery the charging process takes longer and this can also overcharge the battery A sulphated battery will only accept current with difficulty and consequently the charging process takes a particularly long time A worn out battery cannot be fully charged Therefore you should always check whether the charger has been switched to maintenance charge before you leave it turned on or unobserved for any length of time Caution If the US 800 does not switch to maintenance mode after three days it has to be manually disconnected If the set has been switched to maintenance charge then everything is in order Note A battery that hasn t changed to maintenance charge after three days is most likely worn out and needs to be replaced All other batteries can be maintained for a very long time BATTERY TYPES The following recommendations should only be considered as guidelines In the event of uncertainty always refer to the battery manufacturer s recommendations US 800 is suitable for charging all types of 12V lead acid batteries open batteries MF Wet AGM and most GEL batteries Battery sizes from 2 to
