Status: offline 		I have a Peak Electronics Sirius Charge Pro Series field charger. It has 250, 500, and 1000 mah settings. I want to charge my Sanyo 1650 mah NiMh batteries with it. Will this fast charger damage my NiMh batteries ? It charges my NiCds just fine, but I am told that NiMh shouldn't be fast charged ? ? ?

Thank's for your help. - Ed

In my opionion any battery can be charged at 0.8C so even your fastest setting should be okay. That said you may get more cycles if you charge at 500mah when you are not in a hurry. Anyhone else?!......

I would charge it  at the  0.5 amp setting  for about 3.5 hours max .

Status: offline 		The Sirius charger that I am using doesn't have a timed option, it's a "peak" charger. It stops charging when it estimates the batteries are fully charged. So is there a chance that it will not fully charge my NiMh's ? I'm also concerned about them over heating if charged too fast. Is there anyone out there who is using this charger to successfully charge 1650 mah NiMh's ?
