The issue is likely that NiMH batteries are 1.2 volts per cell fully charged, while standard non rechargeable AA alkaline batteries are close to 1.6V per cell, so the flash, which was designed for 1.5-1.6v batteries, “thinks” the NiMHs, are almost completely discharged even when actually completely charged (an alkaline battery at 1.2 volts is almost completely discharged). If the flash will fire and recycle adequately, just ignore the warning.
Agree. My local retailer (WEX) also advised me of this. I also bought a charger with discharging and refreshing modes which I use ocassionally.
