The $20/month battery habit I needed to break

My tactical flashlight burns through CR123A disposables like there's no tomorrow. Every month, another $15-20 on fresh batteries. When I spotted this rechargeable pack for $5.58, I figured it was too cheap to work properly. Two months later, I have real data.

What you actually get for six bucks

I tested this in my two main LED tactical lights. The pack includes four 3.7V CR123A batteries rated at 2600mAh, plus an intelligent charger that auto-stops when done. Build quality feels surprisingly solid for the price point.

What surprised me: runtime matches disposables closer than expected. In my primary flashlight, I get 4-5 hours continuous at max brightness. Premium disposables gave me 5-6 hours, so we're talking about a 15-20% difference.

The charger is smarter than it looks. LED indicators show charging progress, and it genuinely stops when batteries hit full capacity. Complete charge takes about 3 hours.

The part they don't advertise

Worth noting that inserting and removing batteries from the charger requires actual force. The contacts are extremely tight. Not a defect, but definitely annoying until you get used to it.

After 15-20 charge cycles, I started noticing slight capacity reduction. Nothing dramatic, but it's measurable if you're tracking runtime carefully.

CR123A Rechargeable Batteries: Do They Actually Replace Disposables?

What $5.58 normally buys you

At this price point, you'd typically get 2-3 name-brand disposables. Or generic rechargeables without any charger. This pack delivers four batteries PLUS the intelligent charging system.

Compared to premium options like Energizer rechargeables ($25-30), these obviously won't match the cycle life. But for casual to moderate use, they perform the job without drama.

Buy it if this describes you

Buy it if: you regularly use flashlights, gas detectors, wireless alarms, or other CR123A devices. If you spend more than $10/month on disposables. If you want affordable backup power for emergencies.

Skip it if: you need maximum professional performance 24/7. If your equipment costs thousands and you can't risk compatibility issues. If you only use batteries occasionally.

My honest take: 7/10. A solid alternative that pays for itself within 2-3 months of normal use.
