It means those particular cells are drawing heavy balance current during the charge. The charger is trying to bring all cells into balance. Watch the charge Amps to determine when the charge is complete.

Another question is the GT500 limits me to 20 amps regenerative discharge for NiMH batteries, but the specs of gt500 call for a 25 amp discharge.

Also the powerlab 8 limits me to 20 amps for NiMH even though it is speced at 40 amps.

Thanks for any input into this.
Hi:

The PL8 supports up to 40A regen discharge when you use the following preset:

A123 2300 mAh High Power

Hi:

Sorry, my bad. I miss-read your post. I thought you were talking about A123 cells. At the time we designed the PL8, the highest capacity Ni cells on the market were 5AH. We chose to limit max. charge and discharge currents to 4C for safety reasons.
