Hello everyone,
My intelligent battery chargers (Nitecore D4 and Nitecore New i4) rejects some NiMH rechargables. It charges for a few seconds to minutes, then rejects them by showing an error message (there are no details).
This happens to somewhat used batteries and old ones, all kinds of brands (GP, memorex, ikea, ...).
Other, seemingly similar batteries are no problem.
The weird thing is those rejects charge well in a dumb charger, and thereafter are accepted just fine by the intelligent ones.
What is happening here? Am I doing something wrong?
Thanks in advance
