Charging a 9.6v RC battery with a wall wart?
« on: October 23, 2003, 06:49:13 PM »
I resently got a 3000mah battery to power my ua-5 (which should arrive saturday!) and it came with a AC adapter with a Tamiya connecter at the end .... how the hell do i use this thing w/o overcharging the battery? Or do i just stop being a cheap ass and buy a "smart" charger down at the local rat shack?

if it helps here is a photo of what i'v got:
ADK A-51s LE's > Oade W-mod UA-5 > Zoom H4n Pro if I bother to drag out a full rig. More often just the H4N Pro. My LMA tapes

The way i understand rechargables is that they get "warm/hot" to the touch when they have fully charged.  This is what i have been doing with mine.  You probably could make a good estimate of the time by seeing if the mAh the AC/DC puts out.  I have an adapter that puts out 2000 mAh, and i have 4000 mAh batteries, so I plug mine in to a wall timer set for about 2 hours and 15mins (assuming it's drained all the way) and let it go.   I haven't tried it as of yet but i bought a cigarette adapter for my car, and I am going to try that too (for on the road use).  If anyone has experience with that please let me know.

i believe this has been discussed in quite a few other threads.

if my memory serves me correctly, you wont overcharge the RC batts.

if you charge them for 15-24hours, you should be good for about 6hrs+ running the UA5 with phantom. i have no clue how long the UA5 will last without phantom, which is how i run it, but i might try and test it one day.

btw, i have the same set as what you have in the pic above in your post.

If your wallwart is the same as the one I got with my 3000mAh, then it's output is 200mAh. If your battery is completely drained it will take 15 hours to fully charge.
Governor Jim McGreevey was equally disturbed about the upcoming population increase. "New Jersey cannot support all of these wookies," he said. "For starters, we don't have nearly enough kindbud. At best, we can muster up a Q.P. of some beasties, but we've not a dime-bag more."
