Low Battery Light stays on even with new battery and good charging voltage from alternator. Any suggestions? I believe this has been discussed in the past.

From the Manual:
When battery (or PCM) is disconnected and connected, some abnormal drive symptoms may occur while vehicle relearns its adaptive strategy. Charging system set point may also vary. Vehicle may need to be driven to relearn its strategy.
