Does" 7.2v 3600 mah Ni-MH" fit"output=DC 15.0 v 0.8A charger"?
 

do they fit each other??
it should fit,at least theoretically,i think?
am i right??

Need more info, brand and type of charger?

its " GFP 121U-1508"
with the input of AC 100-240v 50/60 Hz 0.3A and the output of DC 15.0v 0.8A.

actually its typical G&G AEG charger,and packed with the 9.6v 1400 mAh Ni-Mh.they fit each other well.
so i derive that it should fit the 7.3v 3600 mAh...

if it's for the same battery type; lipo, nimh, nicad, etc. It should still work however, a good smart charger is 1000x better than any basic wall charger.

Isnt it unsafe to charge a 7.2v battery with a 9.6v charger? Wouldnt overcharging occure? Geta Pirhana Digital Peak Charger. They're sexy.

As long as the connectors mate up, it'll charge it, just slowly. 3600/800 is ~4.5 hours charging.

More voltage puts more current in faster. What's really important is the delta peak.
Anyway your battery is what drives your gun. If your battery dies, your gun won't run on wishful thoughts or hope. The life of your battery depends entirely on how much money you spent on your charger.
So you can have a crap charger, and you battery can be at 60% performance all the time, which means your gun is at 60% performance all the time. Or you can get a good smart charger and have your batteries at 100% all the time.

another interesting thing:when i plugged the charger into a socket,why it didnt give me any voltage as it reads "output=DC 15.0v 0.8A"? the current is also close to zero...
but the charger still works for that kind of condition.
instead,for some other chargers,which should output a constant DC,but when i measured the output,it also stayed around a pretty low DC,then the charging died,it couldnt charge any NiMhs,even the one had been charged by that charger before.

can anyone explain this to me??

I'd say throw it in the garbage and get a decent charger.
