The CR123A battery is trendy in various devices, including cameras, flashlights, toys, security systems, dog collars, and similar devices.

When you label a lithium battery, you have to mark it with a lot of information. The information you must put on the label is called the part number. The part number has to be written in a certain way. For example, the part number for a CR123A battery is CR123A.

It can, however, confuse and even cause issues with devices powered by such batteries if similar labels are used to identify different battery chemistries.

Batteries 34.5 x 17.0 mm, non-rechargeable

These are ‘standard’ lithium 3.0V CR123A batteries, which are not rechargeable, measuring 34.5 x 17.0 mm.

CR-123A, CR17345, CR123, DL123A, and similar products are additional non-rechargeable lithium 3.0V batteries.

However, many manufacturers also use the standard CR123A label to avoid confusion to the greatest extent possible.

Rechargeable Batteries with a dimension of 34.5 x 17.0 mm

The RCR123A, 17345, 17340, 17335, and 16340 are commonly used labels depending on the exact dimensions of the battery, which may differ by just a fraction of a millimeter and still fit into the standard CR123A battery compartments.

There are 650-700 mAh and 3.2 – 3.7 volt RCR123A batteries, but they can still be recharged hundreds of times (chemistry dependent).

Since they do not self-discharge as fast as CR123A batteries, you need to recharge them periodically, even if you are not using them.

The RCR123A and CR123A batteries differ in voltage, so they aren’t always compatible – most devices can accept both types of batteries, but before replacing CR123A batteries with RCR123A batteries, check your device’s Owner’s Guide.

Unlike unprotected RCR123A batteries, protected RCR123A batteries have electronic boards that monitor battery parameters and prevent undesirable events such as over-discharge, over-charge, overload, and short-circuit.

The best RCR123A batteries should always be protected over unprotected RCR123A batteries. Therefore, only charge them with chargers designed for such storms.

RCR123A vs. LiR17335 Battery

  • A CR123A battery measures 34.5 mm by 17.0 mm,
  • An A-size battery measures 50.0 x 17.0 mm.
  • Two-thirds of 50 millimeters equals 33.333 millimeters.

Because of this, 2/3 A batteries such as CR123A are sometimes listed as 34.5 x 17.0 mm batteries.

As BR batteries, they are non-rechargeable carbon-monofluoride lithium batteries, and they have nominal voltages between 2.8-3.0 volts, cutoff voltages between 2.0-2.25 volts, and 1200 mAh.

However, carbon-monofluoride lithium batteries have an extensive temperature range and have meager self-discharge rates, often below 1% annually.

BR-2/3A and BR17335 lithium batteries are often carbon-monofluoride lithium batteries, denoting their chemistry and physical size.

How to Choose Replacement Batteries?

You must be careful when replacing batteries. Even though finding a new one with the same dimensions may seem straightforward, the stakes are high.

You can damage the device if you choose the wrong output or chemistry. Replacing a lithium battery with another lithium-chemistry battery is usually only possible.

Secondly, if the machine drains the battery beyond its capacity, there is a risk of damage to the battery. Finally, the manufacturer’s specifications may also prevent compatibility between some brands.

You could lose money if your batteries do not work, which would be the best-case scenario. 

Be sure to think about some essential factors before taking the plunge, such as:

Non-rechargeable versus rechargeable

However, it’s not always the best idea to be able to avoid buying replacement batteries. 

Most rechargeable batteries cannot handle the higher voltage of some devices. If you are looking for a replacement, stick with Duracell 123 batteries.
