If your clock isn't keeping time, here are some things to consider:

When choosing the proper batteries for your clock, please consider the following information: There are many brands of alkaline batteries available on the market today, but there are several brands out there that just don’t perform well in clocks. In the past few years battery manufacturers have added an extra plastic coating on the negative end of the battery, which can cause clocks to malfunction or not work properly at all. Alkaline batteries are the only type of battery that should be used in clocks. Lithium powered or re-chargeable batteries will cause your clock to malfunction, or not function at all. Lithium and rechargeable batteries are meant for “high-drain” devices, such as digital cameras, etc. Alkaline batteries are best used in “low-drain” devices, which includes clock movements. There are now batteries that are made for low drain items. Here are links to some we have found:

Note, that both of the links above specifically designate their batteries for “Low Drain” items.

We have also found others that work well in battery operated clocks and this is one we recommend:

There are other AA alkaline batteries that work well. Usually a less expensive AA Alkaline battery works better than some of the expensive name brand batteries when it comes to low drain items such as clocks.

Other things to consider if you clock isn’t working:

1. Is there any corrosion on the metal contact points inside the battery well? If so, clean the contacts thoroughly.

2. Is the clock movement that you are trying to use fully charged? A new battery will be charged to 1.5 volts or higher when it is new. If you have a battery test, you could use that to check the voltage reading.
