NiMH 4.8V 2000mAh Hydrimax - charge rate?

Hi, I have two of these NiMH battery packs and am wondering what is allowed for charge rate. Manufacturer states a 200mA 11 hour charge rate is recommended; but can I</span>charge 1.0A with my Triton 2 - do NiMH requires super low 1/10C charge rates?
Thank you for any insight.<br type="_moz" />

No, NIMH do not require low charge rates. But there is a catch with these cells. A low charge rate over longer time they tend to hold the charge better. I have several of their packs and they do last a long time. I just use the 50ma wall wart chargers. They also seem to be a low self discharge cell. They will hold the charge for a long time just sitting there.

RE: NiMH 4.8V 2000mAh Hydrimax - charge rate?
Yes, the first charges on any Nixx (NiMh or NiCad) should be at 0.1C for 15 to 16 hours as this insures that all cells get a full charge and are balanced. Any time that you leave a Nixx battery dormant for a month or more you should always do a slow charge (0.1C for about 16 hours) to fully recondition it and get the most out of it. On a new battery, it may take up to 3 cycles of slow charge (discharging at not greater than 0.33C rate down to 1 volt/cell between charges) to get maximum capacity out of them. Here are some good reliable source of good info on how to care for your Nixx type cells:

My Feedback: (2)
There are high charge rate NiMh and low charge rate NiMh. Receiver packs are typically low charge rate and that sounds like a receiver pack. But some receiver packs are made of the same batteries that the motor packs use.
When not in a rush, charge at 200 mah. When trying to charge faster You can probably take it to 1 amp but I would not do it as the primary charge method for that pack.
If that was a motor pack it would probably tell you you can charge up to about 3 amps.
