They work best for high voltage torches, cameras and LED lights. However, they might not be suitable for replacing 123A’s in lighter devices like alarms that might get damaged by the higher output.
They typically have a capacity of between 700 and 1000 mAh depending on the specific brand. This means they will give you a lower run time than with a primary Duracell 123A battery.
18650 Cylindrical Lithium Batteries
The 18650 battery is a rechargeable lithium-ion battery with dimensions of 35 x 18 mm. Their physical size is within the same range as 123s which means they make a suitable replacement.
Their output is between 3.6 and 3.7 volts. 18650 batteries are a good match to 123s for replacement in high drain devices like your camera, torch or LED lights.
The battery capacity ranges from 2000mAh to 3500mAh, so you’ll get a longer cycle time with these cells.
What to Consider When Choosing Replacement Batteries
Replacing your batteries with new ones is a delicate process. While it may look as easy as finding a different one with the same dimensions, there is a lot at stake.
For starters, if you don’t get it right, you can damage the device, especially if you choose one with the wrong output or wrong chemistry. For instance, lithium batteries can usually only be replaced by another one with lithium chemistry.
Second, you risk causing damage to the battery itself if the machine drains it beyond its capacity. Some brands may also not be compatible, depending on the manufacturer’s specifications.
The best-case scenario is that the batteries will simply not work, which would sadly mean money down the drain for you.
So before you take the plunge, take time to think about some important factors like:
Rechargeable vs Non-Rechargeable
While the promise of not having to buy replacement batteries may seem appealing, it's not always the best-case scenario.
Some devices cannot handle the higher voltages of most rechargeable batteries. In which case, it's best to stick to primary Duracell 123 batteries for your replacements.
The Device's Output
The rechargeable equivalents of 123 batteries are lithium cells best suited for high output devices like your camera.
However, for low output devices, the long-lasting power of 123 batteries like the Duracell 123 can go for over 10 years. Because you will only replace them a few times during the life of the device, you won't need a rechargeable replacement.
If you aren't too sure which way to go when choosing your replacement, ask the experts for some guidance.
Frequently Asked Questions
What’s the Best Way to Dispose of Your Old Batteries?
The chemicals in the batteries can be harmful to the environment. That’s why you shouldn’t throw them out with the rest of your garbage.
Instead, separate your batteries and take them for recycling to your nearest waste management centre or recycling drop off facility.
Remember not to tamper with the cell’s casing and avoid puncturing or exposing the cell’s contents.
Also, ensure that you discard all the used ones when you replace your batteries. Never mix old and new batteries in the same device or else your devices may not work properly.
Does It Matter Which Battery Charger I Use If the Batteries Are of the Same Size?
Batteries may have the same size but different chemistries, which means they will charge differently. For instance, you can’t charge lithium batteries in a nickel-cadmium battery charger.
It’s best to buy batteries together with a charger and stick to the same type and brand of batteries every time you buy new ones.
