Charge light cam on

Ok guys my charge light came on, went to go get my battery tested out. Turns out I had a bad cell but the battery was 100% tested. I bought a new battery and put it in but the charge light did not cut off. Should I be concerned? Its been driving fine.

Should you be concerned, well the short answer is "yes" because you will need to verify that the alternator has at least 13.7 to 14.1 volts output with all accessories off and engine at idle. That battery light indicates that the voltage regulator has encountered a problem and the battery may not be getting the entire full charge that it needs. You had a bad cell in that last battery and I suspect that it may have caused some damage to the voltage regulator circuit, thus that is why the charge light is still illuminated. It is either a bad voltage regulator, faulty connector or connector pins not making good contact to flow the current thru the wiring. Some have mentioned leaky e.c.u capacitors, possibly a faulty e.c.u will certainly cause as problem such as this.
