I have the KX-TG5632CM cordless Panasonic phone. There is a charge light (red LED) that when you put the handset back on the base turns on indicating that the handset is being charged. But it never goes off. I am afraid it keeps the batteries in charge and will damage the batteries. prescription drugs without a prescription Does yours go off? (Even if you have a similar model, cordless with answering machine, it would help)
