Understanding Battery Equivalents: A Guide To CR1620, SR44, And CR1225 Batteries

Today we live in an advanced world, where devices are very essential that will run batteries, so it is more important to have an idea about what are the batteries that will keep our devices going. If you need clarification about which battery to use, then this guide is your ladder to the disarray of CR1620, SR44, and CR1225 batteries and also their equivalents. Read further.

Understanding CR1620 battery

CR1620 battery equivalent is commonly found in small electronic devices such as watches, calculators, and car keys. This is a lithium CR1620 (most popular in use due to its long life and reliability). For replacements, you have probably found some in the market with the name, like batteries CR 1620. So, make sure that any replacement substance fits the requirements of the device so that it will not be confused.

SR44 Battery and Equivalents

Another common style of battery is the SR44, which actually sees some use in digital cameras, medical devices, and even select old calculator models. Using silver oxide chemistry, it offers a stable voltage and longer life than an alkaline alternative. It may also be called by different names like SR 44, SR-44 battery, or even SR44 batteries.

If you are looking for some other options, then you should know that the SR44 battery equivalents are LR44 and AG13. While it does not have the best longevity, it is also not the worst, but only the battery that the chemistry is much better at holding power in high-drain devices.

CR1225 Equivalents

For smaller devices, the CR1225 battery is a popular choice. This 3-volt lithium battery is renowned for its durability and efficiency. Variations, like CR1225 batteries, 3 volt battery CR1225, and CR1225 3v battery all point to the same power source. If you’re in a pinch and need an alternative, the CR1225 battery equivalent might be listed under different brand names but should offer similar performance. Always double-check the compatibility to ensure it fits and functions correctly in your device.

Choosing the Right Battery

When choosing a battery, consider the device’s requirements, expected battery life, and the conditions where it will be used. Here are some quick tips:

  • Check the Device Manual: Always refer to the device’s manual for the recommended battery type. This ensures optimal performance and longevity.
  • Consider Usage: For high-drain devices, opt for silver oxide batteries like the SR44 due to their consistent output and longer lifespan.
  • Equivalents and Compatibility: Verify the compatibility of battery equivalents to ensure they fit and function properly in your device.


Q: Are there rechargeable equivalents for these batteries?

A: Yes, it is right to say that rechargeable equivalents exist but may not be applicable for all devices. Always check the device specifications before using rechargeable batteries to ensure compatibility and safety.

Q: How do I dispose of these batteries safely?

A: Proper battery disposal is crucial. Most communities have designated recycling centers. As the batteries contain toxic materials it is advisable to not throw it into the regular trash.
