This is our NEW 3 volt Renewable Power Source, based on an internal Lithium Iron Phosphate (LiFePO4). It will power any 3 volt self winding clock. Traditional Label. If you used one of our previous 1900R units first produced in 2006, it is time to upgrade to this wonderful new technology. By now, your original Lead-Acid 1900R is nearing the end of its pro-rated life and will need to be replaced.
The Model 1900R3 is our third generation renewable No. 6 utilizing Lithium-Iron Phosphate cell technology. This new technology is a by-product of today's trend towards electric and hybrid vehicle development. Lithium-Iron Phosphate technology is considered by battery manufacturers to be the lowest self-discharge and safer lithium technology available. Its energy density far surpasses the performance of other battery technologies. The charging method - constant current with overcharge termination--results in the fastest charging unit we've ever produced; fully recharging in under 12 hours.
One of the biggest advantages of the 1900R3 is that no cell conditioning is needed for the output. The internal cell voltage is 3.3 volts! This improves run time and reliability, and even timekeeping in most applications. The capacity of the 1900R3 is 10 Amp-hours, double that of the original 1900R. We’ve found that a single 1900R3 will run a typical Style F Self Winding Clock Co. model in good condition for well over 1 year before requiring recharge. Clocks with damaged platinum contacts, dirty winding components in need of oil, or misadjusted winding mechanisms cause laborious or lengthy winding, wearing the internal cell much quicker. Five-minute wind Broadcast Studio clocks will require more frequent charging. Nothing is better for powering impulse-style or Hipp-Toggle self winding clocks (such as American Clock Co., New York Standard, Imperial, Gregory models) than the Model 1900R3.
The 1900R3 includes the plug-in wall adapter to charge the unit. Our new adapter is NOT compatible with our old. So if you have used our previous models, please do not use the old charger with the 1900R3 LiFePO4. It simply won't work.
NOTES: We also have a very nice 24 volt version of the 1900R3 for powering Telco SWCC clocks. Contact us at firstname.lastname@example.org for more details if interested.
If you are an international customer, please contact us about our improved 1900R2 Cyclon lead-acid unit which can be economically shipped overseas.
NOTE: This product can be shipped in the continental US ONLY. International orders are not accepted on this product.
Unless otherwise noted at Checkout, a handling fee of $3.00 is included in each order (also covers packaging material) in the continental United States. Therefore the total shipping number shown in Checkout is the sum of the actual fee (from the carrier) plus this handling fee. The Model 1900R, because it is Lithium technology, must be shipped by ground service. We cannot ship the Model 1900R3 to PO Box addresses!
Ken's Clock Clinic reserves the right to adjust shipping fees or carriers to accommodate order size. If an adjustment is necessary you will be notified prior to shipment.
Important Note: Please allow standard 1-2 week delivery ARO unless otherwise noted in product description. Many products are built to order; all are handcrafted to assure impeccable quality. Timing products (such as the Model 1900S and 1900W series) require pre-shipment calibration and verification which requires time to validate quality performance.
Important Information and Warranty Terms
Prices are shown in U.S. Dollars (USD).
We make every attempt to provide information needed to choose the right product. We encourage you to contact us if in doubt. Restocking charge is 20% of product purchase price on most models.

We strive to learn from any defective product. If a unit is modified or disassembled, this destroys the root cause traceability and an opportunity to improve product is lost.
There are some products (for example, the Model 1900-24V) which are non-returnable due to their low sales volume or custom nature. These are noted in the product description. Please contact us to verify application before purchase.
On-line purchases are processed securely. Credit card purchasing is available through this system. Please contact us if you wish to purchase via some other means.
Sales tax of 8.25% will be applied to residents of Texas.
What is covered by our 5 year warranty on Renewable Units:
- Internal battery holder
- Internal wiring and electronics, connectors (all products)
- Rechargeable Cell on 1900R units, subject to pro-rating.
The only products subject to pro-rating are the 1900R family rechargeables. With these, for every year from manufacture you will need to pay $10.00 plus return shipping to have it refurbished. The 1900R products are serialized for tracking purposes.
What is NOT covered by our 5 year warranty on Renewable Units:
- We do NOT cover the internal alkaline cells which are user replaceable.
- Any unit which has been tampered with or altered voids warranty.
- Return shipping is users responsibility.
- Products over 5 years old and any 1900R with a 1000 series serial number. If your 1900R with 1000 series serial number fails, we will happily refurbish it for $50.00 plus shipping.
