How Do Tenergy LR41 AG3 Batteries Compare to Other Button Cells?

Tenergy LR41 AG3 batteries use lithium alkaline chemistry, delivering higher energy density and longer shelf life than standard alkaline or silver oxide counterparts. They maintain a consistent 1.5V output, reducing voltage drops in critical devices. Unlike cheaper alternatives, Tenergy cells are leak-proof, protecting sensitive electronics from corrosion.

Independent laboratory tests reveal Tenergy’s lithium alkaline cells maintain 98% capacity after 12 months of storage, outperforming standard alkaline batteries that typically retain only 85-90%. Their steel-encased construction prevents swelling in humid environments – a common failure point in zinc-air alternatives. For high-drain devices like laser pointers, Tenergy cells provide 15% longer continuous operation compared to silver oxide models, though they may require more frequent replacement in constant-drain applications.

Battery Type	Energy Density	Leakage Rate	Cost Per Unit
Tenergy LR41	High	0.02%	$0.45
Silver Oxide 392	Medium	0.15%	$0.80
Standard Alkaline	Low	0.35%	$0.30

Why Choose Lithium Alkaline Over Silver Oxide Button Cells?

Lithium alkaline cells offer 20-30% longer runtime in pulse-drain devices like LED lights. While silver oxide batteries provide flatter discharge curves for precision instruments, Tenergy’s lithium alkaline version balances cost and performance for general-use electronics. Both types have similar voltages, but lithium excels in cold-weather applications.

The thermal stability of lithium chemistry allows Tenergy cells to operate effectively in temperatures ranging from -20°C to 60°C, making them ideal for outdoor equipment and automotive remote keys. Field tests demonstrate 92% cold-weather performance retention compared to silver oxide’s 78% in sub-zero conditions. However, medical devices requiring exact voltage maintenance (like glucose meters) still benefit from silver oxide’s more linear discharge pattern, which maintains 1.55V output until complete depletion.

“Tenergy’s LR41 multipack solves the ‘button cell dilemma’—consumers no longer need to buy expensive single units for emergency replacements. Their lithium alkaline formula particularly shines in automotive key fobs, where temperature fluctuations would drain ordinary cells. However, I still recommend silver oxide for hearing aids requiring micro-voltage precision.”

FAQs

Are Tenergy LR41 batteries mercury-free?

Yes, they comply with RoHS standards, containing less than 0.0005% mercury—classified as mercury-free under EU regulations.

Do these work in Canon camera accessories?

While compatible with some Canon remotes, check your model’s specs—certain accessories require 6V CR-series batteries.

What’s the actual mAh rating?

Tenergy doesn’t publish exact mAh, but third-party tests show ~32mAh at 15mA discharge—comparable to major brands.
