A NEW ACCUMULATOR

A new type of accumulator battery, likely to prove a serious rival to the latest wireless receivers operated entirely from the electric light mains, has been produced in Europe, and, it is understood, will be placed on the market shortly. I No details of the construction of the new battery have yet been made available, but it is claimed for it that it possesses many times the electrical capacity of an ordinary lead accumulator of equal weight. This means that one of the new batteries weighing as much as an ordinary lead accumulator would operate a receiver many times longer without recharging than a lead battery. to obtain a given capacity, say, 20 ampere hours, one of the new batteries would be only a fraction the size and weight of a corresponding lead battery. The advantages of these features will be obvious to all those who have had to carry lead batteries to and from charging stations. It is stated that a battery operating on the new principle can be made so light and compact that it can be carried in a large pocket, but at the same time it will operate a receiver of average size for a month or more. Receivers worked from the electric light mains have been developed mainly to overcome the trouble of charging . heavy and cumbersome batteries. Unfortunately, complicated and costly apparatus is needed entirely to replace batteries, and any form of battery that will overcome the disabilities of pres-ent-day accumulators will find wide popularity.
