The first Electric Timex watches were produced in 1962, and the line ran until 1981. These vintage watches have gained popularity among collectors, but finding the right battery for them can be challenging. The battery type often isn't indicated on the case or battery hatch, and cross-reference charts may not always include these older models. Some sources suggest that modern batteries like the LR44, SR44, or AG13 can work, but with potential performance issues due to voltage differences. Finding the correct battery for a vintage ladies' Timex Electric watch requires careful research and consideration to ensure compatibility and avoid damage.

What You'll Learn
- The 357 (SR44W) battery is a suitable replacement for vintage Timex Electric watches
- The AG13 battery is the right height but may not have the power to start the watch
- The LR44 battery is 1.5v and may cause performance issues
- The AG5 battery is the right size according to a cross-reference chart
- A battery slightly larger than the original may work if it has the same voltage

The 357 (SR44W) battery is a suitable replacement for vintage Timex Electric watches
The 357 battery is also known as the SR44W, LR44, SR44, or AG13. While the LR44 is a 1.5V battery and may be underpowered for the watch, the 357 battery is a 1.55V battery, which is closer to the original and should provide smoother running.
The 357 battery is a suitable replacement for vintage Timex Electric watches, which were produced from 1962 to 1981. These watches featured a unique back-set movement, with the mechanism managed by a recessed crown on the back of the case, rather than a traditional side-mounted crown.
When replacing the battery in a vintage Timex Electric watch, it is important to consider the age and condition of the watch. The movement may be stiff with dry oils, so it is recommended to make snappy swinging motions to get the watch running and keep it running. Additionally, the electrical connection may need cleaning if there is soot from sparking.

The AG13 battery is the right height but may not have the power to start the watch
The AG13 battery is the right height for a vintage ladies' Timex Electric watch, but it may not have the power to start the watch. The AG13 is an alkaline battery, and these are known to lack sufficient power to drive some watches. The voltage of the AG13 battery had dropped to 1.15V, which was not enough to get the watch moving. A battery with more power may be required to start the watch.
A battery with a higher voltage may be needed to get the watch ticking. A 357 (SR44W) battery is a possible alternative. While this battery is larger, it has been known to fit, and it has the power to start the watch. The LR44 battery is another option, but at 1.5V, it may be slightly underpowered and cause performance issues.
If you are set on using the AG13 battery, it may be worth trying a fully charged one. The AG13 battery that was tested had a voltage of 1.15V, which is lower than a new battery of the same type. A new AG13 battery may have a higher voltage, which could be enough to start the watch.
It is important to note that vintage Timex Electric watches are sensitive, and incorrect batteries can cause damage. It may be worth consulting a professional or a watch forum for advice before proceeding.

The LR44 battery is 1.5v and may cause performance issues
The LR44 battery is a suitable replacement for the original Timex Type 1 battery, which is no longer easily available. However, due to its lower voltage, the LR44 battery may not provide sufficient power to drive the watch mechanism effectively. This can result in slower timekeeping, inaccurate time display, or even complete stoppage of the watch.
It is worth noting that some users have reported success with the LR44 battery, while others have experienced performance issues. The variation in outcomes could be attributed to factors such as the specific model of the watch, the condition of its internal components, or variations in battery quality.
To mitigate the potential performance issues associated with the LR44 battery, vintage watch enthusiasts recommend using a 357 (SR44W) battery as a replacement. This battery option operates at a higher voltage, providing sufficient power to drive the watch mechanism reliably. However, it is important to ensure that the battery is in good condition and free from leakage to avoid damaging the watch.
Additionally, proper maintenance and care of the watch are crucial. Regular cleaning and servicing can help optimize performance and prolong the life of the watch. It is advisable to consult a professional watchmaker or a vintage watch specialist for guidance on battery selection and maintenance practices to ensure the optimal functioning of your vintage ladies' Timex Electric watch.

The AG5 battery is the right size according to a cross-reference chart
If you're looking for a battery for your vintage ladies' Timex Electric watch, you may need to do some research and possibly some trial and error. It seems that Timex didn't indicate the correct battery anywhere on the case or battery hatch, and these days it's almost impossible to obtain old NOS TIMEX cells. However, there are some options you can try.
Firstly, according to one forum user, the AG5 battery is the right size for a vintage Timex quartz watch, according to a cross-reference chart. It's worth noting that this user had a 1972 Timex watch, which may differ from your vintage ladies' Timex Electric watch.
Another option to try is the 357 (SR44W) battery. This has been suggested by multiple forum users as the correct battery for the Timex Electric watch. However, one user reported that the LR44 battery, which is a similar size, only ticked for a minute and then stopped. This could be because the LR44 is a little underpowered at 1.5V, while the 357 is 1.55V.
If you're unsure, it might be worth taking your watch to a jeweller or watch specialist who can advise on the correct battery and fit it for you. It's also important to note that electric watches are very different from conventional mechanical watches, so it's crucial to get the right battery to avoid damaging the watch.

A battery slightly larger than the original may work if it has the same voltage
If you are looking for a replacement battery for a vintage ladies' Timex Electric watch, you may need to do some research and experimentation. While the original battery for these watches was a Timex Type 1, these are now almost impossible to find.
One option is to try a battery that is slightly larger than the original but has the same voltage. In one case, a user reported that they took their old battery to Radio Shack, and were shown a battery that was just a fraction of a millimeter larger but had the same voltage. This battery worked for their watch, but it is important to note that this may not be the case for all watches, and there is a risk involved in trying a larger battery.
Another option is to cross-reference the battery size with a chart, as some batteries, such as the AG5, are known to be the proper size for certain vintage Timex watches. Additionally, you can try measuring the dimensions of the original battery and finding a modern battery that matches those dimensions as closely as possible.
It is worth noting that some batteries, such as the LR44, may be close enough in size to fit the watch, but may not provide sufficient power, leading to performance issues. Therefore, it is important to consider both the size and voltage requirements when choosing a replacement battery for a vintage ladies' Timex Electric watch.
