I have an AGM battery but my car doesn't have a start-stop system. Can I still charge the battery with a START/STOP charger?
Yes, you can.
Is the START/STOP a simpler charger than the MXS 5.0? It has only three lights while the MXS 5.0 has eight.
No. On the MXS 5.0 a light shows for every step, and the voltage and power curve is shown above and below the lights. On the START/STOP we've chosen to reduce the number of lights and instead just show which phase the charger is currently in – Check, Charge or Care. START/STOP has no programme selection. Instead, when it is in contact with a battery it starts as soon as it's plugged into a wall socket.
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 the positive charger terminal) and the negative clamp (or eyelet) is connected to the chassis (or the negative charger terminal), and not the other way round.
Can I charge my battery through the cigarette lighter socket?
2. To exclude the possibility of a problem with the charger, test it on another battery.
3. The charger may have discovered a problem inside the battery. The charger will try repeatedly to continue, but if it cannot, it will switch over to error mode.
Depending on where in the programme the charger has stopped, it is possible to identify a number of causes. If the Check light and Error indicator (!) are both lit at the same time, try restarting the charging cycle by unplugging the charger from the outlet and plugging it in again. If it stops again at the same point, the battery is sulphated and probably needs to be replaced. There can be other problems with the battery that mean that the charger can't go beyond Check mode.
If the charger enters error mode when "Charge" is lit, it is due to a problem with the battery's ability to retain charge. This can also happen if the loads on the battery are too great, making the voltage decrease too quickly. Disconnect these loads and try again.
If your cigarette lighter socket is connected to the battery even when the ignition isn't on, you can charge the battery that way. You need a CONNECT Cig plug or a INDICATOR Cig plug for this.
Does START/STOP have temperature compensation?
How do I know the battery is fully charged?
When the green "Care" light shows, the battery is fully charged.
How should I connect the charger? My car has BMS (Battery Management System)
Connect the red clamp (or eyelet) to the battery's positive (+) pole. You can connect the black negative (-) clamp (or eyelet) to the chassis or a recommended earthing point.
What's new about the START/STOP charger?
START/STOP has been developed for modern cars with a start-stop system. It's simple to use as it doesn't have a programme button (mode button) – it starts working as soon as it's connected to a battery and is plugged into a wall socket. It's also easy to understand, as it only has three LEDs which show which phase it's currently in: Check, Charge or Care.
Can I use the charger during the winter? It doesn't have a winter setting.
Yes, you can use the charger during the winter, as it has an inbuilt temperature sensor which regulates the output voltage depending on the ambient temperature.
Can I charge a standard car battery that is not installed in a start-stop car?
Yes. START/STOP is optimized for use with 12 V EFB (Enhanced Flooded Battery) and AGM batteries, but it can charge ordinary 12 V lead-acid batteries as well.
What do the three stages on the charger mean?
Check mode means that the charger is checking the battery’s state of health and preparing to charge. If the battery is in good condition, the Check stage doesn't take more than a few moments.
How many amps does START/STOP provide?
The Charge mode LED shows while the charger is filling the battery, and Care shows when the battery is fully charged and the charger has automatically switched over to maintenance charging.
It provides a maximum of 3.8 A and varies according to the needs of the battery.
