The Hobbico quick field charger is a good charger. A slow charge is best for a new battery, but you should be able to quick charge the battery at 1.5 to 2.0 amps without any harm to the battery.

If anybody makes a wall wart well suited for trickle charging a 1700 Mah NiCd/NiMH pack, I sure haven't seen it. Wall warts generally can't provide enough current to charge that large of a pack sufficiently. You need 170 Mah or so for the charge rate, and most wall warts typically charge at 50 or 75 Mah.

A more advanced charger might be a good investment. I bought the Super Brain 989 about eighteen months ago, and it's amazingly flexible. It can charge at rates from 100 Mah to 10 Amps, can handle NiCd/NiMH packs from 1 to 25 cells, can discharge and autocycle NiCd/NiMH packs, can handle LiPo packs from 1 to 8 cells, works well with a variety of balancing modules, can charge 6v to 24v lead acid batteries, and comes with its own 10 Amp AC power supply.

The SB 989 has so many features that I couldn't adequately explain them all. It was not inexpensive, but I constantly use it for cycling receiver packs and balance charging LiPos.

The 100Mah charge rate is low enough to be appriopriate for slooooow charging a brand new receiver pack, even if it's only 600Mah or so in capacity. It can be increased 100Mah at a time and be set to exactly how fast I want it to charge.

The $144.99 price tag may seem ridiculous at first glance, but you can knock $25 or $30 off the cost if you hit the right Tower Hobbies discount code. I caught it on sale back in Jan '07 and got one for $110 delivered. I use the charger so often now that I've never regretted a nickel of the money I spent on it. I can't imagine ever using an RC battery of any kind that the 989 won't charge. I just don't have to worry about it.
