I don't consider this an advantage. Most Lester chargers I've seen have 
too high a finish rate (8 amps typical), causing excessive water use and 
shortening service life.  I've heard that they can be ordered with a 
lower finish rate (4 or 5 amps, I think) but dealers seem to seldom stock 
them that way.  

Also, their DV/DT charge controllers are a good idea, but they often 
don't shut off soon enough.  They are supposed to shut down the charger 
when the voltage increase levels off, but sometimes don't do so until the 
battery has heated up enough for the voltage to actually drop.
