I recently bought an SRC M933 M4 from a friend with a red dot sight and an extra mag, The battery is an 8.4v battery pack. However, the problem is that whenever I leave the battery plugged in the gun, it loses charge. Also, Even after it was freshly charged, and I dont even put it in the gun, it also loses charge. Is the battery supposed to be like that? Or should I buy a new one?
Batteries will lose charge if they just sit there for a while. At least mine do. For example, if i charge my battery for 6 hours then un plug it and just let it sit, the next day it will have no charge. This is the same with all of my batteries so its probably how they all are. At the same time if the 8.4v was the battery that came with the gun (lile included in the package) i would reccomend buying a new one, as the ones that come with the gun are of lesser quality. Hope this helps!
