I can't guarantee that I will be at home when the
charger says it's finished. Should I disconnect it and
continue charging when I come home?
No, you don't have to monitor on the charger. It will automatically switch to maintenance
mode and keep the battery fully charged until you return. If you want to leave the battery in
maintenance mode long term, you should make sure that the charger has successfully
charged the battery and that the "Care" light is showing.
The charger has switched to error mode. What could the
problem be?
1. First check that the charger is connected correctly. Check that the positive clamp (or eyelet)
is connected to the battery's positive pole (or emergency start point) and the negative clamp
(or eyelet) is connected to the chassis (or suitable body earth or ground), and not the other
way round.
2. The charger has discovered a problem inside the battery. The charger will try repeatedly to
continue, but if it can't, it will switch over to error mode. Causes can include cell faults,
sulphation, or the battery's capacity to retain charge.
Try first to restart the programme by pressing the Mode button.
Error mode can also be shown if the loads on the battery are too great, making the voltage
decrease too quickly. Disconnect these loads and try again.
3. Test the charger on another battery to exclude the possibility of a charger fault.
Can I use the charger for long term maintenance?
Yes, you can. The charger switches automatically to maintenance charging when the battery is fully
charged.
No LED or display is lit when the charger is connected
only to the battery.
The plug has to be connected to the mains output for the LED & and the displays to be lit.
No LED or display is lit when the charger is connected only to the power outlet.
No LED or display is lit when the charger is connected
only to the power outlet.
The displays and LED should light up when the charger is connected to the power outlet.
Please test to make sure that there is power from the power outlet.
What is ripple and how does it affect batteries?
Ripple is a measurement of the AC power leaking through to the DC side of the charger. High
current ripple results in the heating up and drying out of a battery and in a shortened
lifetime. High voltage ripple results in imprecise charging and can damage a vehicle
