After replacing the battery I drove the car for about 45 minutes (averaging 65mph) when the battery light came on, followed by my stereo cutting off, airbag light cutting on, security light turning on, and my fuel gauge dropping to empty. I was close to home when this happened and was able to park it before it completely died on me. The engine had a very strange growling sound, and there was a bad aroma coming from the engine.
The guys at Merchant's Tire, who I had just bought the battery from after getting some major engine work done, paid to have it toed back to their shop to see what was wrong. We were thinking they had forgotten to reconnect the alternator or something, but it turns out the battery just had a bad cell in it and wouldn't charge. I am quite glad Merchant's was gracious enough to pay for the toeing out of their pocket and fix any damages they may had caused. I'll be picking it back up today.
