[D8962AAV], Letter from Colorado and Utah Phonograph Co to North American Phonograph Co, July 22nd, 1889

Editor's Notes

We are about discouraged in regard to "Batteries."##We received two of the New No. 1 batteries by express at a cost of $26.00 express charges hoping to get a battery that would do the work as represented.##We set up the first one following the printed instructions, minutely and find as follows:-##It was full 48 hours after setting up before we could turn motor.##We short circuited about ten minutes. The Voltage we were unable to get, but it is evidently very low as it will run motor only to reproduce.##There seems to be a great range current strength in jars probably owing to the depolarizing material. On close circuit one jar registers 10 amperes, one 8, one 7, and one 3. All four connected in series close circuit 7 amperes,- when motor is running one and a half amperes.##We have used battery two and a half hours in one week and that is all we could get out of it. We opened up the second battery and found one of the jars broken and as we cannot get anything to replace it here, it is useless to us at present. It may be possible that we have gotten hold of one that is not just right. We have three more coming and will try them, but if they work no better than the first one they are no good to us.##As things are at present, we cannot lease Motor Power Phonographs. We feel very much disappointed, as we have been promising some of our people to furnish a battery as represented to us, to replace the first battery, and said patrons are disgusted and say that we must take back the machines.##This hurts our reputation as others were waiting to see how this battery would work. Can you enlighten or help us out in any way?##Have you tried the Pumpelly Storage Battery? What would be the cost of recharging, etc., etc."
