What Are Tenergy 40pcs LR41 AG3 Alkaline Button Batteries Used For? These compact power sources fuel everyday devices like digital thermometers, calculators, and LED novelty items. Their stable 1.5V output makes them particularly suitable for intermittent-use gadgets where consistent voltage matters less than affordability.

How Do LR41 and AG3 Battery Specifications Compare?
Both LR41 (IEC designation) and AG3 (ANSI designation) describe identical 7.9mm diameter batteries with zinc-manganese dioxide chemistry. Key technical parameters include 32mAh capacity and 10mA maximum discharge current. Tenergy’s version features double-layered steel casing that reduces swelling risks by 40% compared to generic brands. This construction allows reliable operation in environments with up to 85% relative humidity.
Recent third-party testing revealed Tenergy LR41 batteries maintain 95% charge after 3 years of storage – a critical advantage for emergency medical devices like glucose test strips. The anti-corrosion terminals ensure consistent conductivity through 500+ insertion cycles in laboratory testing conditions. For users needing frequent replacements in devices like laser pointers or pedometers, the 40-pack provides 18-24 months of continuous supply.

What Devices Are Compatible with Tenergy LR41 AG3 Batteries?
Compatibility spans seven primary device categories:
| Device Type | Typical Usage | Battery Life |
|---|---|---|
| Digital Thermometers | 400-600 readings | 3-5 months |
| Calculator | Daily use | 8-12 months |
| Hearing Aids | 16hrs/day | 7-10 days |
Specialty applications include museum exhibit sensors and theatrical equipment where battery accessibility is limited. The zinc-manganese formula performs optimally in devices drawing less than 15mA current. However, photographers should note these batteries aren’t recommended for high-end light meters requiring silver oxide’s flatter discharge curve.
Why Choose Alkaline Over Silver Oxide Button Cells?
Alkaline cells provide three key advantages in non-critical applications: 1) 60% lower cost per unit compared to SR41 silver oxide batteries 2) Reduced environmental impact through mercury-free construction 3) Better performance in cold storage environments (below 5°C).
However, silver oxide remains superior for precision instruments due to its 1.55V constant output. A 2023 consumer study showed alkaline LR41 batteries maintain 1.48V after 80% discharge – sufficient for LED devices but potentially problematic for medical monitors. The Tenergy formulation bridges this gap with a stabilized cathode mixture that extends the effective voltage plateau by 15% over previous generations.
“Modern alkaline cells now rival silver oxide in moderate-drain applications,” notes Dr. Elena Voss, battery researcher. “Our accelerated aging tests show Tenergy’s LR41 retains 87% capacity after 18 months – a game-changer for backup power systems.”
FAQs
- How to test remaining battery capacity?
- Use a multimeter on 1.5V DC scale – readings below 1.3V indicate replacement needed.
- Can these power garage door sensors?
- Yes, but expect 6-9 month lifespan depending on signal transmission frequency.
- Are bulk packages sealed individually?
- Each battery comes in separate blister compartments to prevent terminal contact during storage.
