Is this a true statement?

This question is for the Triton Charger. Here is the scenerio. I have 5 NiMH Sub-C Cells in a stick/series configuration for charging. If one of the cells in the stick reads 1.27v and the remaining cells read 1.1v the charger will shut down whichever the cell reaches it's full capacity first thus the remaining 4 cell are actually not fully charged. The Triton is a one channel charger right?

Hello Dukester,

The Triton is a one channel charger.

When you put 5 cells in series, you end up with a battery pack. The Triton will charge the pack until it reaches 7 volts or slightly higher. 1.4 volts per cell for 5 cells = 7 volts.

To balance the cells in the pack you need to do a reduced current charge for a longer time. The ideal way to balance a pack is to charge it at a 0.1C rate for 14-16 hours.

What Silverfox stated is true but there is more to it than that. The Triton will charge the pack of cells until its peak voltage is reached and the voltage then drops. The peak voltage reached can vary each time the same battery is charged. The Triton tries to sense the number of cells in a pack by the voltage during charging. It then uses its derived number of cells and multiplies that by the peak voltage drop per cell to determine when to terminate the charge. In your case, with one cell having more of a charge to begin with, that cell will likely be overcharged instead of the other cells being undercharged.
