What are AG13 batteries and their equivalents?

AG13 button batteries are super common little power sources for all sorts of electronic gadgets. Let’s break it down:

AG13 Battery Equivalent

What are the specs for AG13?

• Standard voltage: 1.5 volts (V)
• Max continuous current: about 20 milliamperes (mA)
• Operating temp range: -20°C to 60°C
• Size: diameter is 11.4 mm, thickness is 5.8 mm

Chemical composition:

AG13 batteries usually have silver oxide (Ag2O) for the positive side and zinc (Zn) for the negative side. The electrolyte mainly includes silver chloride (AgCl) and sodium hydroxide (NaOH) solution. When the battery discharges, the zinc powder slowly dissolves in the electrolyte, while the silver oxide gets reduced to silver, which ends up on the negative electrode.

Service life and storage:

You can typically keep AG13 batteries stored for several years without any drop in performance, depending on how you store them. Their lifespan while in use really depends on the load current and the environment. If you’re not using the battery for a while, it’s a good idea to take it out of the device and stash it in a cool, dry spot.

Alternative models:

If you’re looking for alternatives to AG13 batteries, you can check out LR44, SR44, 357A, and A76. These might have a few small differences in size and chemical makeup, but they usually work interchangeably in most cases.

Manufacturers:

Some popular brands making AG13 batteries include Duracell, Energizer, Panasonic, Rayovac, and Varta. These companies put a lot of effort into making sure their AG13 batteries are reliable and safe with ongoing research and quality checks.

Environmental impact:

AG13 batteries do have heavy metals and chemicals that can be a bit nasty for the environment, so it’s super important to dispose of used batteries properly. Some places have special recycling programs just for batteries to help reduce waste and keep the environment cleaner.

Development trend:

As people become more environmentally aware and tech improves, manufacturers are working on creating greener battery options and rechargeable solutions. The goal is to cut down on waste and make batteries more efficient and sustainable overall.

What batteries can replace AG13?

AG13 coin cell equivalents are other battery models that match AG13 in size, electrical performance, and compatibility. Here are some common options:

LR44 battery:

The LR44 is an alkaline coin cell that works pretty much the same as an AG13 and can often be used as a replacement. Even though the chemicals inside might be different, they’re the same size and fit in the same battery slot.

SR44 battery:

The SR44 battery is another popular replacement for AG13. It uses silver oxide, which means it has better conductivity and lasts longer. SR44 and AG13 are the same size, so they fit perfectly.

357A battery:

The 357A is also an AG13 equivalent, especially in North America. It provides 1.5 volts and works great in the same small electronics.

A76 battery:

The A76 battery is often mentioned as an alternative to the AG13 coin cell. There might be a few differences for specific uses, but they usually work interchangeably.

When picking an equivalent for the AG13, make sure the size, voltage, and current match what your device needs. Different coin cells can vary in chemical makeup, which might affect performance and lifespan, so keep that in mind. It's always best to follow the device manufacturer's advice or ask a pro.

Which manufacturers produce AG13 batteries?

AG13 batteries are small button cells found in all sorts of gadgets like calculators, watches, and remotes. Many manufacturers make them, including big names like:

• Duracell
• Energizer
• Panasonic
• Sony
• Varta
• Maxell
• Rayovac
• GP Batteries

Besides these well-known brands, there are plenty of smaller and generic ones out there too. Since AG13 batteries are super common, you’ll find a lot of options. They might come under different brand names and packaging, but they all meet the same standards.

Summary

AG13 coin cell batteries are popular because they're small, reliable, and easy to find. As gadgets keep evolving, AG13s will still play a big role as small power sources.

Frequently Asked Questions

Is AG13 the same as LR44?

Yes! LR44 replacements include Duracell 76A, Energizer A76, and AG13 batteries. They’re all the same, just different names, and can be swapped out for each other.

Is AG13 the same as 357?

Yes, the Energizer 357/303 battery is equivalent to the AG13. You can use the 357/303 to replace AG13s in watches, medical devices, laser pointers, and more.

What is the equivalent of the AG13 cell battery?

AG13 batteries, also known as Alkaline Zinc Manganese button batteries, are mainly used in watches. They’re also called LR44, 157, A74, or LR 1154, and they’re the same size and voltage as SR44 batteries, which are sometimes called 357.

What is the difference between AG12 and AG13?

AG12 (LR43) is 4.2mm thick, while AG13 (LR44) is 5.4mm thick. The larger AG13 has a higher capacity: AG12 = 55 mAh and AG13 = 60 mAh.

Can I use Energizer 357 instead of LR44?

The 357 is a silver oxide battery at 1.55v, while LR44 is an alkaline battery at 1.5v. Silver oxide usually lasts 30% - 100% longer and gives a steadier voltage until it drops to 1.2v, compared to 1.0v for alkaline. They’re mostly interchangeable for most uses and cameras. Helpful?

What else is LR44 equivalent to?

LR44 batteries are in the alkaline category, with equivalents like A76, AG13, G13, LR1154, L1154, and 154. Silver-oxide options that can replace these alkaline types include SR44, SR44SW, SR44W, SB-B9, 303, and 357.
