DUSLAN 12-Pack 7/5 AA 3.7V Li-Ion 14650 920mAh standard battery

12-pack 7/5 AA lithium-ion cells

These 14650 batteries deliver 3.7 V and 920 mAh each, supplying higher voltage than standard alkaline AA cells. They suit devices built for the 7/5 AA form factor such as specialised torches, medical instruments or industrial sensors. The flat-top terminals ensure a solid connection in spring-loaded holders. Buyers needing common 1.5 V AA replacements cannot use these cells.

Flat terminals and 14 mm diameter

Each cell measures 65 mm long by 14 mm wide and weighs 24 g, matching the 7/5 AA envelope so existing battery compartments accept them without modification. The lithium-ion chemistry removes memory effect and supports long storage life. Maximum charge current is 0.9 A and maximum discharge current is 1.8 A, so the pack works with chargers and loads rated for those limits. Devices requiring button-top contacts or a different diameter will not fit.

Replaces single-use 7/5 AA primaries

The rechargeable pack replaces disposable lithium or alkaline 7/5 AA batteries, cutting waste and recurring cost for high-drain equipment. The jump is worth it when the device draws enough current to exhaust primaries quickly and the host can handle 3.7 V per cell. Applications locked to 1.5 V chemistry or lacking a compatible charger gain no benefit.
