There are trouble codes listed for your charging system, anything? I can't go by what somebody else said, your battery and alternator, tested off the vehicle may be fine, I'd have to do testing with everything hooked up on the vehicle. Use a digital multimeter across your battery posts, everything turned off, 12.6 volts is the generic spec for a fully charged battery. Then, start the vehicle, take second reading across battery posts, the second reading should be higher than the first if charging system is working. Have you checked for excessive battery drain, everything turned off? Shouldn't exceed 35 milliamps, .O35 amps.
