As we rapidly approach the 10-year anniversary of the Model 1900G regulated battery, it seems a good idea to take a closer look at this old friend.
The economical Model 1900G will SAFELY power any 3 volt self winding clock. It combines state of the art voltage regulator technology with ultra-capacitor technology, emulating exactly the series combination of two original, vintage No. 6 batteries.
Alkaline battery technology has greatly advanced. Today’s alkaline D cells are incredible given their size and cost. They fall short when you need high impulse energy to wind impulse clocks like American Clock Co., Keyless Clock, Imperial, or Hipp-Toggle. Until now, we could only offer a rechargeable (the Model 1900R series) for these demanding clocks.
Some alkaline D batteries perform better than others with impulse loads. Some have longer amp-hour lives than others. We need some way of leveling the playing field with these various alkaline technologies. The Model 1900G answers the call.
When you use alkaline batteries alone to power impulse-wound clocks such as American Clock Co., Keyless Clock, Imperial, or any other impulse-wound clock, the batteries never seem to last. When alkaline D batteries have been depleted of only 1/3 their capacity, their available impulse energy drops off substantially. At that point, they cannot reliably wind the clock. You replace the batteries and the cycle starts all over. You end up throwing away good batteries with energy left in them, which is expensive and environmentally unfriendly.
Historic electric clocks were designed to be powered from a pair of No. 6 batteries. Because of its extremely large physical size, the historic, original No. 6 delivered high impulse energy and low cell resistance for a substantial part of its life. Newer battery technologies alone cannot offer this without help. Internally, the Model 1900G “conditions” the alkaline battery output so that the total cell resistance is kept very low. The terminal voltage is also “regulated” to a constant level. These attributes together are the key to powering impulse-wound clocks.
The Model 1900G is unquestionably the best product to use for impulse-wound clocks. It is a 3.3 volt cell and therefore only one unit is needed. However if for aesthetic purposes you desire two No. 6 cells, we offer the Model 1900-BL companion cell which can be wired in series with the Model 1900G to provide the original nostalgic look. The 1900-BL is not needed when batteries are not visible (eg, mounted on top of the clock, out of view).
