Seems odd that you are getting a POR (power on reset) at 4.8V.  Well within the USB low voltage spec.
Do you have a voltage meter?  Maybe you have a bad cell or a cold joint somewhere.  Older NiCd or NiMH can
develop some dendritic micro-shorts.  Various ways of burning these out. Here is one way:

Personally, I just used a generous overvoltage for a second.
