It will be better for the batt if you don't use charge/discharge rates more than 1amp. It takes some time, but I cycle mine at 0.5a/0.5a.
It could be worth considering the crystals as the culprit. I had the same issues, but when I changed the crystals, it disappeared. Try with another set of crystals, and see if it works then. If the rcvr is not properly secured and left to move about while your're driving, it can get banged around, and that may have damaged the rcvr or crystal. Good luck mate.
