Ken’s Clock Clinic is pleased to offer the Model 1900 Vintage Dry Cell Battery Collection for Self-Winding Clocks and other vintage electrical devices. These products replace obsolete No. 6 batteries such as the EN-6. Long Life and G cells will run most clocks for 2 years. We also offer 24 volt models for special self winding clocks such as the Bell System long distance billing timers and Stromberg vibrating winders.

All 1900 Series products are respected for their high quality and are warranted for 2 years. Stainless steel hardware, heavy knurled nuts, and pleasing vintage aesthetics are what you will experience. On the inside, soldered connections throughout, protection circuitry (on 3 volt and Long Life models), and reliable electronics are what distinguish our products. Hundreds of our products are in the hands of our very satisfied customers.

All No. 6 units come with internal alkaline flashlight D batteries installed and ready to go. You never throw the Model 1900 products away. Internal alkaline flashlight D cells are replaceable. Down the road, your maintenance battery changes will cost less than $4. That is a small fraction of what it would cost to replace a pair of EN6!

Model 1900 Series No. 6 Battery Selector Guide

If you are replacing batteries in a Self Winding Clock Co. of New York or "Western Union" model, look to see if there are synchronizer coils. These are two large black cylinders on the right side of the movement. If there are, we strongly recommend you purchase the Model 1900GS No. 6 Synchronizer Kit. This kit powers the clock, AND provides a replica of the Western Union impulse to your clock's synchronizing coils on the hour. Your clock will retain its vintage appearance while rekindling the nostalgic experience of daily time synchronization once provided by the Western Union service. The 1900GS Kit is calibrated so that your clock will become more accurate than any quartz watch on the market. Click here for a historical overview of Western Union clock synchronization with a tutorial on the 1900S Synchronizer.

If you prefer, you can purchase the Model 1900R/1900S Kit instead of the Model 1900GS Kit above. The Model 1900R is rechargeable! That means you will never have to take the battery out of the clock again! Otherwise it is exactly the same as above.

If your clock does NOT have synchronizing coils, then the Model 1900L Long Life is the preferred choice. The Model 1900L uses two alkaline D batteries in each No. 6 unit. It is great for clocks, vintage telephones, cigar lighters, etc. It is the close equivalent to the EN6. We recommend the 1900L as the replacement for the obsolete EN6 when synchronization is not desired. Available in red Long Life label or traditional label.

If you are replacing the batteries in a Hipp-Toggle, American Clock Co., Imperial, Trinity, or Gregory impulse clock, then you should use the Model 1900G (also a No. 6 unit). This is an alkaline D battery-powered No. 6 National Carbon Co. unit that produces a solid, regulated output of 3.3 volts. That means that the clock will wind as if it has fresh batteries in it, every time. A single 3.3 volt unit takes the place of two traditional 1.5 volt No. 6 units. The 1900G, with its internal regulation and ultracapacitor technology, is very efficient in its use of the battery's energy. That means it provides exceptionally long run time for any clock. Read our technical bulletin here.

Note: These products provide the correct voltages and signals originally intended for these self winding clocks. In addition to restoring the vintage aesthetics, they replace unsightly transformers or circuit board modules, rectifiers, black boxes, or batteries with incorrect voltages. They also untether the clock from power cords so the clock can be located anywhere. Click here for a reference table of Self Winding Clock voltages.
