DUSLAN 6-Pack AAA 3.7V Li-Ion 10440 350mAh standard battery

High-Voltage AAA Replacements

These DUSLAN 10440 cells deliver a nominal 3.7 V in the familiar AAA form factor, providing three times the voltage of standard alkaline or NiMH AAA batteries. The lithium-ion chemistry gives each cell a 350 mAh capacity and a flat-top terminal design. They are intended for devices specifically engineered for the higher 3.7 V input and are sold as a six-piece pack.

Upgrade from Alkaline or NiMH AAA

The jump is worthwhile only when the target equipment explicitly requires or supports 3.7 V lithium-ion cells in the 10440 size. Standard 1.5 V alkaline or 1.2 V NiMH AAA batteries cannot be substituted directly because the voltage difference can damage sensitive electronics. These cells replace older lithium-ion 10440 packs with similar voltage and capacity ratings, offering a fresh set with no memory effect and long storage life.

Suits Experienced Electronics Builders

The pack suits hobbyists and technicians assembling or repairing custom battery packs, high-performance flashlights, or specialised instruments that demand 3.7 V AAA-size power. Buyers must understand lithium-ion charging and discharging limits, including the 0.35 A maximum current ratings, to avoid safety hazards. Casual consumers looking for drop-in replacements for ordinary household remotes, toys, or clocks should look at standard 1.5 V alkaline or 1.2 V rechargeable AAA batteries instead.
