There's more to it than just capacity, Chuck.  The BLM-01 have + - and T 
connections, the T being a temperature sensor to cut the charging if the 
battery gets too warm (although that may not be the primary measure of 
charging).  The BLM-05 have in addition an S connection. I don't know what it 
does. Paging Tim Hughes!

I think we need Tim's advice but I would bet that the old charger would charge 
the BLM-5 (the contacts and voltage are the same) but it might not get the 
BLM-5 to full capacity.  The BLM-1 is 1500 mAh, the BLM-5 is
1620 mAh.  The charger has to have intelligence to shut itself off when 
charging is complete.  Failure to do so is a potential hazard for the battery, 
possible fire or explosion due to overheating I think.  I don't know how the 
shut-off mechanism works, whether voltage or ???
