irrintxi Posted February 3, 2021 Report Share Posted February 3, 2021 Hi, I have a hammer drill te 2a with a charger that might have an issue. The charger model is C7/36-ACS and when I power it, the green led lights up --> OK. When I place the drill battery, after few seconds the green led blinks. According to the manual, "A malfunction in the charger or battery was detected during the self-test." Si I purchased a new battery thinking the problem was with the battery. I have then tried with the new battery but it happens the same so I suppose the malfunction is in the charger? I have open it and found nothing apparently bad, at first impresion. Does anyone have some experiences with this charger or similar? Any clues will be very wellcome! Quote Link to comment Share on other sites More sharing options...
Eric - TIA Posted February 4, 2021 Report Share Posted February 4, 2021 No idea because I haven't had a battery or charger fail by Hilti. If you reach out to their local service center, i am sure someone can give you more information. Quote Link to comment Share on other sites More sharing options...

Just to confirm, with the charger connected to mains and without the battery plugged to it, between the 2 battery charging connectors should be 24v, or a bit more, right? I have measured and there is only 5v. Quote Link to comment Share on other sites More sharing options...
