The Adams Express Company has forfour months been operating with this battery four of its deliverywagons, and at the present time the manufacturers claims havebeen equalled. While a much longer experience will be requiredto determine the value of this battery, it is theoretically directed inthe proper line of improvement and, therefore, worthy of mostcareful consideration. It suffers, however, from its higher cost andthe large amount of charging energy which is lost in 2,000-pound wagon which now sells for $2,500 would cost $3,005with this battery, while the saving in weight is only 375 pounds, andthe battery requires 60 per cent, more energy than is required in. FIG. 4.—ELECTRIC TRUCK. charging lead batteries. In the case of the 2,000-pound wagon thismeans $204 per annum, instead of $ with the lead battery. Itwould seem fair to expect more repairs with the Edison analysis of the different items show, however, a net gain perton mile for the Edison battery amounting to quite a considerableamount, being 13 per cent, in the 2,000-pound wagon, 12 per cent,in the 3-ton wagon, and 125/2 per cent, in the S-ton truck. The Plante battery above referred to. which is known as the Manchester type, has a strictly Plante positive plate and whatis called a box negative plate, and is stated to be unquestionablythe longest-lived and most rugged storage battery in existence. Thecost of maintenance of this battery is discussed and the calculationshows a net gain practically identical with that of the Edison instance, in the 2,000-pound wagon it will cost for cents per vehicle mile.
