Ever popped open a gadget – maybe a laser pointer, camera, or flashlight – and found yourself face-to-face with a tiny, mysterious battery labeled "CR123" or "CR123A"? Don't be fooled by their similar names and size; these little powerhouses have distinct personalities and price tags. Let's delve into the world of CR123 vs. CR123A batteries and help you choose the champion for your device.

Size Matters (But Not That Much)

At first glance, these batteries appear identical. Both boast a cylindrical shape, measuring 34.9mm tall and 17mm in diameter. However, a subtle difference emerges: CR123A batteries are ever so slightly thicker, clocking in at 3.2mm compared to the CR123's 3.0mm. This seemingly minor discrepancy can be crucial for tight spaces. Some gadgets, like specific camera models, might only accommodate the slimmer CR123, while others happily accept both variations.

Capacity Quandary: Who Reigns Supreme in Stamina?

This is where things get interesting. The CR123A packs a punch with a higher mAh (milliampere-hour) rating, typically offering around 225mAh compared to the CR123's 170mAh. This translates to potentially longer runtimes for your devices, making the CR123A the king of endurance for frequently used gadgets like remote controls or laser pointers.

Cost Crusaders: Who Wins the Wallet War?

Here's where the scales might tip. CR123 batteries are often slightly cheaper than their A counterparts, with the price difference varying depending on brand and quantity purchased. So, if you're powering low-drain devices like smoke detectors where runtime isn't a major concern, the CR123 might be a more budget-friendly option.

While CR123 and CR123A are the main contenders, don't forget these niche players:

• CR1616: This even slimmer option (1.6mm) is perfect for ultra-compact devices like some health trackers.
• CR2016: Offering a capacity similar to the CR123 but in a thinner package, it's another space-saving champion.

Choosing Your Champion: The Verdict is Yours!

Ultimately, the perfect battery is a match made in device heaven. Consult your gadget's manual or manufacturer's recommendations to find the ideal power source.

Here's a quick cheat sheet to help you decide:

• Need a slim fit? The CR123 might be your knight in shining armor.
