For the best performance of your clock we only recommend you use a standard size battery, and that you replace the battery as required, this will ensure your clock runs on time all the time. If the clock has stopped and or losing time, please check that the battery is not flat before returning your product back to the factory under the "Quality Guarantee" terms and conditions.

Please note: Heavy duty batteries may cause malfunctioning of your clock.

                       Rechargeable Batteries use an incorrect voltage and will not run your clock effectively.
