AccuPower IQ338LX charging unequally on 2 of 4 slots

AccuPower IQ338LX

Received this charger from ebay seller rDana Around the first of the year.
Since them I’ve discovered that the charger has a few problems.

Of the 4 slots, several seem to be substantially off in the capacity readings from the others.

For example, I can put a battery in Slot 1 and the capacity comes out at 5330 mAh.
Same battery in slot 2 will show 5100mAh.
Same battery in Slot 3 and 4 comes out 5082mAh. The error is repeatable.

Slot 1 consistently shows about 300mAh too much capacity
Slot 2 consistently shows about 100mAh too much capacity
Slots 3 and 4 seem to be pretty accurate

Anyway to correct this? Resistor change? The warranty probably ended about 2 weeks after I got it.

Thanks

A owner on CPF was having a similar problem, the Germans don't make chargers like they use too, I have had two Tronic charger blow-up and others with faulty slots.

It looks like just Slot #1 is about 175mAh too optomistic.

I have a feeling a resistor change might resolve that.
