Battery Weak Due to Inadiquate Alternator Output on Kia Optima

After the vehicle has been operated with electrical loads (lights, air conditioning), a weak alternator can cause starting difficulties. In some cases, the original alternator could not sufficiently charge the battery; Kia released a new alternator which can correct this concern.

Tried to start the car after work and this weird clicking noise started happening. All the lights came on in the car as usual, but the car wouldn't turn over. Eventually I noticed, while putting the windows down, the electricity was slowly being drained from the car. It happened last night and will be repaired today.

Vehile would not start at all. After I jumped car was running but as soon as you turn off and back on nothing. Thought was battery per dealer replaced only to find out alternator not charging and my car was only running on the battery. Needless to say car is still at dealership as they access the issues with my 2013 Kia Optima.
