David C Robie wrote about his Chinese Smithy XL:(had her for bout 10 yrs, not a week goes by that I don't do something with her, and still deliriously happy with her). I can echo his comment in reference to the instruments used to read power, current, and voltage on my E-20 to check USA Made CR-225 battery charges, the Model P4400 Kill A Watt 125VAC 15A 1875VA, and EXTECH True RMS Multimeter Radio Shack. My wife interrupted the battery charging to use the E-20 to shred leaved on the lawn. The mower does a good job of reducing the dry leaves into smaller pieces so they meld into the lawn. It is much easier and cleaner than collection with the Goat. There are no fumes and much less dust. Three hours of shredding leaves consumed about 3.87 KWH and brought the batteries down to 37.83 volts. Jim Coate wrote that Trojan recommends the following end voltages for a 36 volt system: daily charge: 44.4 volts, equalization: 46.5, constant float: 39.6. He also wrote that one should add 0.5 volts for every 10 degrees below 80 deg F and subtract 0.5 volts for every 10 degrees above 80 deg F. If one assumes that his formula is OK to equalize the new Crown CR-225 batteries in my E-20, the charger would need to reach 46.7 volts. Yesterday I questioned the old GE charger, but not today. After 17 hours the charging voltage reached 47.7 volts before the timer was turned off by me. The charging current started at 9.05A and moved down to 1.85A at turn off. Power was measured at 859 watts and moved down to 119 watts at turn off. Three hours later the batteries read: 6.56+6.53+6.56+6.52+6.50+6.56=39.23V. Now to figure out what this all means to my E-20. I think like David C Robie said the batteries may not be equal but will improve after some use.
