First Thoughts on the Energizer 357 Zero-Merc 1Pk
The Energizer 357 Zero-Merc 1Pk, a seemingly unassuming button cell battery, promises to be the lifeblood of our often-overlooked but crucial gadgets. Energizer, a name synonymous with long-lasting power, aims to keep our devices humming with this mercury-free offering. I was intrigued to see if this tiny power source could truly live up to the brand’s reputation in a market flooded with generic alternatives.
My need for this battery arose from a frustratingly common situation. The rangefinder I use for competitive shooting died mid-practice, leaving me scrambling for a replacement. I was specifically looking for a reliable, readily available battery to ensure I wouldn’t be caught off guard again.
Upon unboxing—or rather, peeling open the blister pack—the Energizer 357 Zero-Merc 1Pk appears simple, yet well-constructed. The small size is deceptive, hiding the potential power within. It felt solid and properly sealed, giving a sense of quality despite its diminutive stature.
Compared to generic, off-brand button cell batteries, the Energizer 357 Zero-Merc 1Pk felt noticeably more robust. I chose Energizer over cheaper options due to their proven track record and the “Zero-Merc” claim, which addresses environmental concerns. Initial impressions were cautiously optimistic; I was eager to put it through its paces.
Real-World Testing: Putting Energizer 357 Zero-Merc 1Pk to the Test
First Use Experience
My initial testing ground was the shooting range, replacing the dead battery in my Leupold RX-1600i rangefinder. The temperature was a brisk 45 degrees Fahrenheit, a typical late fall day. The battery slotted in perfectly, and the rangefinder sprang back to life instantly.
The rangefinder performed flawlessly for several hours, providing accurate readings even in the slightly overcast conditions. There were no noticeable power fluctuations or signs of weakness. This immediate success was a welcome change from the frustrating experience with the previous battery.
Extended Use & Reliability
After several weeks of consistent use in my rangefinder, the Energizer 357 Zero-Merc 1Pk continues to perform admirably. I’ve used the rangefinder during multiple range sessions, hunting trips (though without a shot fired), and even for estimating distances during a recent cross-country hike. There are no signs of diminished performance.
There are no physical signs of wear and tear on the battery itself, as it remains tucked away inside the rangefinder. The battery is still going strong, so I have yet to need to perform any maintenance or care. Compared to the generic batteries I’ve used in the past, the Energizer 357 Zero-Merc 1Pk is demonstrating superior longevity and consistent power output.
