It's a 3300 mAh side by side NiMH battery with a Hitec connector. Not sure how hard I loaded it...I just hooked it into my Axon II microcontroller for the basic upload of the hardware programs. It was never on for more than 5 minutes at a time. I hadnt even gotten a chance to run the servos (2) for the robot.
But anyway, my professor got his doctorate in wireless and telecommunications...he seemed to be confident that I wasnt going to hurt the battery by using the lab power supply at a low ampere setting (.5-.8 amperes). It worked pretty good actually.
800mA is way to high a current for charging this way!
You won't hurt the battery provided you do the following...
You set the PSU to max. 1.45V/cell.
If the battery is really flat, you set the current limiter to max. C100 for starters (that's 33mA in your case) and charge until all cells are at minimum 1.1V/cell (1.2V/cell is better).
When the battery have reached this minimum, you can set the current limiter to C10 (i.e. 330mAh) and charge until the current tapers off to around C100 (33mA) - that should take around 14..16 hours for a completely flat battery.
Remove the charge current within the next couple of days.
This will safely charge the battery, as long as you keep to the exact voltage setting and don't try charging very flat batteries at a high current.
If you get different voltage readings for the cells in a battery, you need an equalizing charge, where you charge with C100 max (C200 is even better, if you can wait that long) and charge them untill they all show exactly the same voltage +/- 1mV.
The shorter the wires from the PSU to the battery and the firmer the terminals are gripped, the better charge.
But it get boring real soon. Getting a good quality charger with fast charge and multiple charge termination techniques, you could charge the same in 2..3 hours without having to remember to disconnect.
And the best of them checks if there's a need for equalization and applies it automatically.
