DUSLAN
DUSLAN 6-Pack AAA 3.7V Li-Ion 10440 350mAh standard battery
Six 3.7 V lithium-ion AAA cells, each 350 mAh, 10 mm × 43 mm, 17 g, flat-top terminals
- Battery TypeAAA
- 6-pack delivers 3.7 V lithium-ion power per cell
- 350 mAh capacity supports extended device runtime
- Flat terminals on both ends simplify installation
- 10 mm diameter by 43 mm length matches AAA form factor
- 17 g lightweight cells with no memory effect
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.

Questions about this item
Will the 10 mm diameter and 43 mm length of these 10440 cells fit my AAA device?
Each cell measures 10 mm in diameter and 43 mm long, matching the physical size of a standard AAA battery, so it fits the same compartment.
How do I install the flat-top terminals correctly and what mistake should I avoid?
Insert each battery with the flat positive end toward the device's positive contact; the common error is reversing polarity because both ends look flat.
When should I replace the 350 mAh cells and how do I store them safely?
Replace when runtime drops noticeably; store at room temperature, partially charged, and keep away from metal objects to prevent short circuits.
