Anyone experience this? My VC4 is a few years old and is acting up. I will put in a discharged battery, it’ll charge it for a few minutes - put in about 50-100mAh and stop telling me it’s full. Tested this with multiple batteries. Some times, I have to disconnect and reconnect power and it’ll charge, but it’s refusing to more often than not. It does this with both NiMH and Li Ion.
Well, I think I’d reach out directly to Xtar and see if they might have some input or perhaps a replacement even though it’s old (there’s always hope). If the basics for contacts/connections, supply and cabling, etc. check out good then it sounds like it’s the logic failing and for safety’s sake that makes it trash unless you can identify and replace a simple component on the board. Might bring it to their attention here in a PM or with a link to this thread on one of their various charger threads…may get a faster reply than trying to email directly as if often the case with overseas companies.
I’m experiencing the exact same thing. VC4 that is approx 5 to 6 years old. Putting in batteries and it will go red for a second then back to green to say they are finished.
After taking them out and turning it on and off i can usually get it to work but it will occasionally stop after a couple hundred mah and I have to reset it again.
I was thinking it was almost time for a new charger.
I think if a li-ion charger lasts more than 3 years, you are doing well. My XTAR VP4 Plus DRAGON lasted 4.5 years until it refused to charge anything. Once they start to play up, it is time to get a new one for safety reasons.
