We obviously need a third opinion here. If you don't already have one, buy or borrow a good Digital Volt Meter and check the voltage on each cell. This should tell you which is off, the TM06S or the charger. Let us know what all the readings are from all three sources and we can go from there.Hi everyone, my indicator light consistently ready a full 2 volts less than what my smart charger indicates. And it claims to be accurate to plus or minus .01 volts.. Is there any way to fix this ? And is it normal?
It says 4.4 dcv on my multimeter. Fresh off the charger. It's a d4 nitecore charger
That's about right when not under load. Most 9v batteries are really six AAAA cells inside. The no-load voltage for a fresh AAAA, like AAA & AA, is around 1.6v-1.7v.
You neglected to tell us what the TM06S and the charger said the voltage was.
