## Discrepancy

HAD A BURNING SMELL IN THE AIRPLANE AND FOUND SMOKE COMING FROM THE BATTERY AND BATTERY CHARGER.  REMOVED AND REPLACED BATTERY AND CHARGER.  THE 737-291  AIRCRAFT HAVE A PROJECT TO INSTALL NEW CELLS.  THE OLD CELLS HAVE BEEN FOUND TO OCCASIONALLY OVERHEAT BECAUSE OF POOR SEPARATOR MATERIAL BETWEEN CELLS.  OPS CHECK GOOD.
