    Signs of a bad battery?

    The batteries are about 4 years old, 3s 5000mah
    One battery charging slower than the other. The charger will ramp up to 3v then fall to less than 1 amp and will end charging cycle at around 4v per cell. I'm thinking they have high resistance and the charger is thinking they are at capacity.
    I know these batteries are junk, but wanted to make sense of what happening.
