- Editor's Notes
- I wish to say a few words to you about the Edison-Lalande battery which we are just commencing to market.##First, as to the cell. The following data will interest you: Internal resistance 025 Voltage on heavy work .75 Local action less than one-half of one per cent. Zinces never require cleaning. 200 of these cells in series have a combined internal resistance of only five ohms, which means that practically all the current is delivered on the line, regardless of the conditions of weather.##The voltage is not high, but that is more than compensated for by the exceedingly low resistance.##We run ten, twenty or thirty wires from a battery of these cells, which facilitates concentration of main batteries at central points and will effect great saving in both investment and maintenance.##For local sounder work we made a test and ran fifteen sounders from two of our cells--there is economy here also.##Isn't this just the cell you want for your quad work? in fact, for all your work. It will enable you to obtain a regular dynamo current at points where it is impracticable for you to use dynamos. We make cells 600, 300 and 150 ampere. I don't want to annoy you with too many details. I hope I have said enough to interest you to the extent of your requesting us to furnish further information to some one of your assistants. We invite the fullest investigation.
