My pair of chargers for my 901 Riva don't charge my batteries. The batteries themselves will charge on my 901 charger but at 100mah output takes all day or night to charge the Riva. I'm used to the oddities of the larger current eGo charger. All of those require me to unplug the charger, plug it back in and then screw in an eGo and it will charge. To charge a second battery I need to repeat the sequence. So I tried that with the Riva 901 chargers. Didn't help. Tried screwing in the Riva and then plugging in the charger. Didn't work. Tried plugging in the charger then the Riva, nope. This is using my 2000mah AC to USB adapter which rules out the AC adapter as the problem. That adapter works great for me with every other charger I own. Also tried it with 2 of my laptops. No go. If I screw the Riva into the standard 100mah 901 charger it immediately turns red and starts to charge. Seems to prove the Rivas themselves aren't at issue. Just the charger.
Luckily I order more from this 2nd batch of kits. The first charger I tried from them works great. So I'm not looking for a replacement. More like the sequence I describe with the eGo charger. I'm hoping other folks have had similar problems and have a solution.
