Default NiMH 4.8V 2000mAh Hydrimax - charge rate?

<span style="color: rgb(51, 51, 51); font-family: Verdana, Arial, Tahoma, Calibri, Geneva, sans-serif; font-size: 13px; background-color: rgb(250, 250, 250); ">Hydrimax ultra 4.8V 2000 mAh NiMH battery
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.

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:

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.
