Well, I finally picked up an extended (SNN5788a) battery & larger battery cover off of eBay for $17 - The battery has twice the capacity as the little BR56 battery, and solved the problem. However, it's twice the thickness and weight, so my phone has a "hunchback" now.
A tech told me that I may be ruining my batteries using the car charger (I've tried two of the BR56's with similar results), because the car adapter charges several times faster than my home charger, even though both are genuine Motorola. He recommends never using the car charger except in emergencies.
