Works out of the box. Only recommendation: clearer documentation on he meaning of the red and orange/green LEDs.

Used as a trickle charger for 6 years with no problems. Handy to have the ability to use either the supplied croc clips or to fix a connector in place on the battery for easy connect/disconnect of the charger.

Good value for money, fast delivery. My battery for Audi A3 was completely flat due to not driving during Covid lockdown. Left the charger overnight and the battery was fully charged by morning.

Ask A QuestionQuestions and Answers

QCan you leave the battery connected to car when using the charger?

AYes, you can safely leave the battery connected to the vehicle as long as it is not running.

QIs this charger suitable for AGM batteries? Our application is a 92AH AGM battery.

AThis is suitable for AGM, but the charge rate is too low for 92Ah batteries. I´d recommend the Ctek MXS 7.0 which has an 8A charging rate.

AYes, the Numax 4A charger is ideal for that purpose.
